Digest is a collection of popular hashing algorithms that comes standard in Ruby. !. Original documentation: https://code.google.com/archive/p/crypto-js/, JavaScript implementations of standard and secure cryptographic algorithms. SHA-256 is a cryptographic hash function that is commonly used in the blockchain and other security-critical applications. I have not verified yet. You signed in with another tab or window. In general, though, and if you want to do anything more complicated than simply executing commands and capturing their output, you'll need to use channels (Net::SSH::Connection::Channel) to build state machines that are executed while the event loop runs (Net::SSH::Connection::Session#loop). The output of this is always this: (if I put '12345' as parameter or 'HUSYED815X', I do get the same). The iter_count parameter lets the user specify the iteration count, for algorithms that have one. SHA stands for Secure Hashing Algorithm, of which SHA2 is the second generation. For example: There's also encrypt! You can convert a WordArray object to other formats by explicitly calling the toString method and passing an encoder. The longest input line that sha256 can handle is 2048 bytes. One of the key features of a cryptographic hash function is that it is one-way, meaning that it is virtually impossible to reverse the process and recover the original input from the hash. The API is not working because of this Can some one help me with that? when establishing a secure TLS/SSL connection. The standard means of starting a new SSH connection. :user => the user name to log in as; this overrides the user parameter, and is primarily only useful when provided via an SSH configuration file. Outputs this keypair in PEM encoding. Additionally, Ruby compiled with OpenSSL >= v1.0.1 will include AEAD ciphers, ie., aes-256-gcm. The OS is Ubuntu 18.04.3 LTS. when establishing a secure TLS/SSL connection. Asking for help, clarification, or responding to other answers. #!/usr/bin/ruby -w Verifies data using the Probabilistic Signature Scheme (RSA-PSS). | . :paranoid => deprecated alias for :verify_host_key, :passphrase => the passphrase to use when loading a private key (default is nil, for no passphrase), :password => the password to use to login, :port => the port to use when connecting to the remote host, :properties => a hash of key/value pairs to add to the new connections properties (see Net::SSH::Connection::Session#properties), :proxy => a proxy instance (see Proxy) to use when connecting, :rekey_blocks_limit => the max number of blocks to process before rekeying, :rekey_limit => the max number of bytes to process before rekeying, :rekey_packet_limit => the max number of packets to process before rekeying. CryptoJS also supports SHA-224 and SHA-384, which are largely identical but truncated versions of SHA-256 and SHA-512 respectively. $\begingroup$ The auth_data is arbitrary contextual information (for instance, the database primary key of the encrypted message, or a username, or a string scoping the action to a specific "purpose") that must be provided verbatim upon decryption. "L3dmip37+NWEi57rSnFFypTG7ZI25Kdz9tyvpRMrL5E=". Instantly share code, notes, and snippets. Defaults to true. Blocks are hashed in series, which means the output of a block is feeds into the input of its subsequent block. The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: . AES is popular because it is considered very secure and is standardized by the National Institute of Standards and . Returning true accepts the host key, returning false declines it and closes the connection. > key = Digest::SHA256.digest 'SecretPassword' This line turns SecretPassword into a 256 bit hash which we can then use. Step 1: Enter the Plain or Cypher Text. When overridden in a derived class, finalizes the hash computation after the last data is processed by the cryptographic hash algorithm. Otherwise, use_ssh_config may be a file name (or array of file names) of SSH configuration file(s) to read. Adds methods to set and authenticate against a BCrypt password. :global_known_hosts_file => the location of the global known hosts file. SHA-1 is a 160-bit hash. The standard docs cover how to salt and hash a password. As PKCS5 is slow, it is optional behavior, but it does provide more security to use a unique IV and key for every encryption operation. Make sure you remove the hash ( #) at the beginning of the line. Where XXX is the attribute name of your desired password. Each of the SHA-3 functions is based on an instance of the Keccak algorithm, which NIST selected as the winner of the SHA-3 competition, but those SHA-3 functions won't produce hashes identical to Keccak. Include following character sets for creating combinations; Encrypt strings to MD5 hashes or decrypt MD5 hashes to strings by iterating combinations, Encrypt strings to SHA1 hashes or decrypt SHA1 hashes to strings by iterating combinations, Encrypt strings to SHA512 hashes or decrypt SHA512 hashes to strings by iterating combinations, SHA256 Decryption with Successful Result after 1.2 Billion Trial (Brute Force). Deprecated in version 3.0. # Load bcrypt gem only when has_secure_password is used. :logger => the logger instance to use when logging. The following validations are added automatically: Password length should be less than or equal to 72 bytes, Confirmation of password (using a XXX_confirmation attribute). This makes hash values useful in encryption and data verification, since they can be significantly smaller than the input value and changing a single bit in the input value will alter the entire hash. When you pass a string, it's automatically converted to a CipherParams object according to a configurable format strategy. Net::SSH tries to manage this complexity by providing some simpler methods of synchronous communication (see Net::SSH::Connection::Session#exec!). This mechanism requires you to have a XXX_digest attribute. Two special values are reserved: :digest means the digest length, and :auto means automatically determining the length based on the signature. This means that if encryption is taking place the data is base64 encoded after encryption. For example SHA1+DES represents all cipher suites containing the SHA1 and the DES algorithms. In most cases, there is no need to call this method. How to Generate SHA256 Hash? See Hashing's Output for more detail. THIS METHOD IS INSECURE, PRIVATE INFORMATION CAN LEAK OUT!!! A CipherParams object represents a collection of parameters such as the IV, a salt, and the raw ciphertext itself. It is also used in various digital signature schemes. Encrypt. Lists of cipher suites can be combined in a single cipher string using the + character. The length in octets of the salt. Encrypt string with the private key. They are primarily used for authentication, tamper detection, and digital signatures. sha3_512 - 64 bit Digest-Size. S3. I got key must be 24 bytes message at this line: Reference http://ruby-doc.org/stdlib-2.0.0/libdoc/openssl/rdoc/OpenSSL/Cipher.html, Doesn't work for me. Most hashes are also stored with their double hash or treble hash, along with binary versions. The Advanced Encryption Standard (AES) is a U.S. Federal Information Processing Standard (FIPS). In non-deterministic mode, Active Record uses AES-GCM with a 256-bits key and a random initialization vector. However, this behavior has been removed to avoid polluting Ruby's core String class. And just to verify that the hash value was created correctly we can take a look at the stored value in the database. Ruby: How to install a specific version of a ruby gem? So, let's get cracking and discover how SHA256 works, step-by-step. A new option is available in Encryptor 3.0.0 that allows decryption of data encrypted using an AES-*-GCM algorithm from Encryptor v2.0.0. https://tools.ietf.org/html/rfc5084#section-3.2. The Encryptor::String module remains within this gem to allow users of this feature to implement it themselves. SHA-224 and SHA-384 are simply truncated versions of SHA-256 and SHA-512 respectively, computed with different initial values. How Does SHA-256 Work? Connect and share knowledge within a single location that is structured and easy to search. You can define your own formats in order to be compatible with other crypto implementations. DES is a previously dominant algorithm for encryption, and was published as an official Federal Information Processing Standard (FIPS). To know how to Decrypt SHA256, you must . Here is a representation of how SHA256 encoder decoder works; there are two different strings with different character lengths, both produces unique SHA256 hashes with 64 characters long. The variety of SHA-2 hashes can lead to a bit of confusion, as websites and authors express them differently. New external SSD acting up, no eject option. Syntax for Sha256 encryption 1 2 $password=$_POST['password']; $hasedpassword=hash('sha256',$password); A the time of signup encrypt the password with Sha256 then insert in to database . See sign_pss for the signing operation and an example code. Store it somewhere safe, e.g. SHA-2 is actually a "family" of hashes and comes in a variety of lengths, the most popular being 256-bit. Defaults to 300 seconds. This new standard was part of a larger effort to strengthen the security of computer systems and networks, and was designed to replace the older SHA-1 standard, which had been shown to be vulnerable to attack. Decrypting SHA256 can seem like a daunting task, but with the right tools and knowledge, it can actually be quite simple. They can be set individually by set_key, set_factors, and set_crt_params. The given string is first encoded as UTF-8 and then the SHA256 algorithm is applied as defined in RFC 4634. In deterministic mode, it also uses AES-GCM, but the initialization vector is generated as an HMAC-SHA-256 digest of the key and contents to encrypt. It is widely used in a variety of applications, including the encryption of internet traffic, email, and sensitive data. Process of finding limits for multivariable functions. It defines three algorithms: one which works on chunks of 512 bits and returns a 256-bit digest (SHA256), one which works on chunks of 1024 bits and returns a 384-bit digest (SHA384), :config => set to true to load the default OpenSSH config files (~/.ssh/config, /etc/ssh_config), or to false to not load them, or to a file-name (or array of file-names) to load those specific configuration files. :verbose => how verbose to be (Logger verbosity constants, Logger::DEBUG is very verbose, Logger::FATAL is all but silent). It is a part of the SHA-2 family of hash functions, which also includes SHA-224, SHA-384, and SHA-512. The OS is Ubuntu 17.10. Set to an array if you want to specify multiple global known hosts files. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. To implement digest in your ruby code, you need to add require digest to access the hashing functions in digest. Always use slow hashes, never fast hashes. The accepted types are: des, xdes, md5 and bf. RSAError will be raised if an error occurs. This is used as a logical and operation. Although remarkable for its simplicity and speed, the algorithm's history doesn't inspire confidence in its security. cipher must be an OpenSSL::Cipher instance. Can we decrypt it and if yes then how? Hashes have been generated from a large number of sources, including procedural generation using multiple UTF-8 charsets, common dictionary lists and also sets of raw binary data. Ruby V3AWSS3!. Find centralized, trusted content and collaborate around the technologies you use most. To review, open the file in an editor that reveals hidden Unicode characters. In many applications of cryptography, user security is ultimately dependent on a password, and because a password usually can't be used directly as a cryptographic key, some processing is required. Older versions of Encryptor added encrypt and decrypt methods to String objects for your convenience. Creates a shallow copy of the current Object. http://ruby-doc.org/stdlib-2.0.0/libdoc/openssl/rdoc/OpenSSL/Cipher.html#method-i-encrypt. Send me a pull request: bonus points for topic branches. :remote_user => used for substitution into the %r part of a ProxyCommand. When you use a CipherParams object in a string context, it's automatically converted to a string according to a format strategy. # Recomended length for AES-###-GCM algorithm. Thanks for contributing an answer to Stack Overflow! padding defaults to PKCS1_PADDING. They are calculated by d mod (p - 1), d mod (q - 1) and q^(-1) mod p respectively. It was selected after a 5-year process where 15 competing designs were evaluated. It lets you specify an alias, similarly to adding an entry in /etc/hosts but without needing to modify /etc/hosts. The database contains millions of SHA256 hashes and matching sources. TL;DR; SHA1, SHA256, and SHA512 are all fast hashes and are bad for passwords. This option is intended for situations where ssh-agent offers many different identites. SHA256 Encrypt/Decrypt is a free online tool for generating SHA256 hashes from strings and decrypting SHA256 hashes to strings. SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". No need to create a digest instance, just put a string represents the algorithm and it works like a charm OpenSSL::HMAC.hexdigest ('sha256', key, data) since ruby 2.5 ruby-doc.org/stdlib-2.5.1/libdoc/openssl/rdoc/OpenSSL/ - Dat Le Tien Jun 1, 2022 at 11:02 Add a comment 20 Try This: If you see "SHA-2," "SHA-256" or "SHA-256 bit," those names are referring to the same thing. Sign in to comment Stores all parameters of key to the hash. This makes it a popular choice for storing passwords and other sensitive information, as it is nearly impossible for an attacker to retrieve the original password from the hash. :encryption => the encryption cipher (or ciphers) to use, :forward_agent => set to true if you want the SSH agent connection to be forwarded. The return value is true if the signature is valid, false otherwise. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Worked just fine with hexdigest! It was withdrawn shortly after publication due to an . Can we create two different filesystems on a single partition? This dependency means that a single changed bit will produce a different result in the output hash. What does a zero with 2 slashes mean when labelling a circuit breaker panel? Returns a hash of the configuration options for the given host, as read from the SSH configuration file(s). RC4 is a widely-used stream cipher. Encryption FTP FileAccess Firebase GMail REST API GMail SMTP/IMAP/POP Geolocation Google APIs Google Calendar Google Cloud SQL Google Cloud Storage Google Drive Google Photos Google Sheets Google Tasks Gzip HTML-to-XML/Text HTTP: HTTP Misc IMAP JSON JSON Web Encryption (JWE) JSON Web Signatures (JWS) JSON Web Token (JWT) Java KeyStore (JKS) MHT . The default is 512 bits. Short summary: What is AES-256 Encryption? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Content Discovery initiative 4/13 update: Related questions using a Machine generating signature using base64_encode and hash_hmac in ruby on rails, How to use intuit webhook verifier token on a webhook, How to understand nil vs. empty vs. blank in Ruby, How to check if a value exists in an array in Ruby. But I'm trying to get rid of the PHP dependency. The values produced by hash functions are usually compressed and have two primary characteristics irreversibility and uniqueness. If you pass the actual key, you must also pass the actual IV. SHA256 Generator can be called as SHA256 Checksum online or SHA256 Calculator. For the key, when you pass a string, it's treated as a passphrase and used to derive an actual key and IV. sha256 computes the SHA256 hash of a given string and encodes it with hexadecimal digits. When you use a WordArray object in a string context, it's automatically converted to a hex string. From there, a program interacts with the new SSH session via the convenience methods on Net::SSH::Connection::Session, by opening and interacting with new channels (Net::SSH::Connection:Session#open_channel and Net::SSH::Connection::Channel), or by forwarding local and/or remote ports through the connection (Net::SSH::Service::Forward). # Insures that the key is the correct length respective to the algorithm used. A simple, secure and modern encryption tool with small explicit keys, no config options, and UNIX-style composability. It's a CipherParams object. It should be named Keccak[c=2d]. Signs data using the Probabilistic Signature Scheme (RSA-PSS) and returns the calculated signature. However, the following ciphers are typically supported: NOTE: Some ciphers may not be supported by Ruby. Clone with Git or checkout with SVN using the repositorys web address. First, it's important to understand that SHA256 is a cryptographic hash function, meaning that it is a mathematical algorithm that takes a string of any length and produces a fixed-length output. Returns the authentication code an instance represents as a binary string. Modules: Authentication, BufferedIo, Connection, ForwardedBufferedIo, HostKeyEntries, Loggable, Proxy, Service, Test, Transport, Verifiers sha-3sha-2 blake2sha-3 Increase to 0x10000 (65536 bytes) for better performance if your SSH server supports it (most do). Clone with Git or checkout with SVN using the repositorys web address. Salted Challenge Response Authentication Mechanism (SCRAM) is the default authentication mechanism for MongoDB. To learn more, see our tips on writing great answers. If you pass the :salt option, a new unique key will be derived from the key that you passed in using PKCS5 with a default of 2000 iterations. A bug was discovered in Encryptor 2.0.0 wherein the IV was not being used when using an AES-*-GCM algorithm. Swift HMAC SHA256. To do this, we can pass the password entered by the user to the SHA256 hash function, which will return a hash value in a bubble babble format. Mostly wrapping of .NET libraries but useful to see it in powershell's befuddling syntax. In general, though, and if you want to do anything more complicated than simply executing commands and capturing their output, youll need to use channels (Net::SSH::Connection::Channel) to build state machines that are executed while the event loop runs (Net::SSH::Connection::Session#loop). By default, 192 words (768 bytes) are dropped, but you can configure the algorithm to drop any number of words. You are trying to set the "encryption key". cipher = OpenSSL::Cipher.new('DES-EDE3-CBC') encrypter = cipher.encrypt base64-encoded. Posted 7-Sep-12 18:51pm vinod 7929592 Add a Solution 1 solution Solution 1 Refer below link: Link 1 [ ^] Link 2 [ ^] Link 3 [ ^ ] Posted 7-Sep-12 18:55pm prashant patil 4987 This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Encrypt some text. It's been used in a variety of security applications and is also commonly used to check the integrity of files. It will generate 64 characters of SHA256 hash string and it can not be reversible. It's used in popular protocols such as SSL and WEP. If use_ssh_config is nil or false, nothing will be loaded (and an empty hash returned). Public Function EncryptSHA256Managed (ByVal ClearString As String) As String Dim uEncode As New UnicodeEncoding () Dim bytClearString () As Byte = uEncode.GetBytes (ClearString) Dim sha As New _ System.Security.Cryptography.SHA256Managed () Dim hash () As Byte = sha.ComputeHash (bytClearString) Return Convert.ToBase64String (hash) End Function HMAC can be used in combination with any iterated cryptographic hash function. The :v2_gcm_iv option is available to allow Encryptor to set the IV as it was set in Encryptor v2.0.0. It isn't as widely used as SHA-1, though it appears to provide much better security. We will use 4096-bit key lengths and SHA-256 as our digest function. If you have a password or email that is hashed with SHA256, you may decrypt it by using these methods. The hash you get back isn't a string yet. The encrypted string output can be decrypted using private_decrypt. Got this line that works well in the terminal (using the fish shell): RSA is an asymmetric public key algorithm that has been formalized in RFC 3447. In this example, our new user Hash Test User is creating a new account with a new username and password. :keys_only => set to true to use only private keys from keys and key_data parameters, even if ssh-agent offers more identities. I am going to show you how the encryption flow actually works using some Ruby code. The following validations are added automatically: Password must be present on creation Password length should be less than or equal to 72 bytes This method is not ideal since a hashing function is not designed to be reversible, so we cannot decrypt the hash and recover the original value that was entered. Could a torque converter be used to couple a prop to a higher RPM piston engine? Defaults to %w(/etc/ssh/ssh_known_hosts /etc/ssh/ssh_known_hosts2). The standard means of starting a new SSH connection. Keyed-hash message authentication codes (HMAC) is a mechanism for message authentication using cryptographic hash functions. However, to maintain backwards compatibility you can run Encryptor with the :insecure_mode option. If called without arguments, creates a new instance with no key components set. A simple wrapper for the standard Ruby OpenSSL library. If confirmation validation is not needed, simply leave out the value for XXX_confirmation (i.e. If you use a passphrase, then it will generate a 256-bit key. When I try to set encrypter.key I always get this error message: key must be 24 bytes. The SSH protocol is very event-oriented. :verify_host_key => specify how strict host-key verification should be. You can encode or decode your text by following these steps. | let hashHex = hash.toString (CryptoJS.enc.Hex) And then, to log it to our terminal, we'll use a regular console.log. sha256 Function. Encryptor now requires a key and IV of the correct length respective to the algorithm that you use. See code as gist 3 Features Ruby V3AWSS3!. 1. pg_ctl reload -D /postgres/datadir. One thing you can do is a brute-force strategy, where you guess what was hashed, then hash it with the same function and see if it matches. It is used to generate a unique, fixed-size string of text (called a "hash") from a larger input, such as a file or a block of data. The encrypted string output can be decrypted using public_decrypt. During each cycle a data block is compressed before being passed on to the next cycle. I should also mention that this script works fine on an Ubuntu 17 machine with Ruby version ruby 2.3.3p222 (2016-11-21) [x86_64-linux-gnu]. Get ready to decode your security worries with SHA256, and let's dive in! Instantly share code, notes, and snippets. Download ZIP Simply encrypt and decrypt Strings in Ruby. Did Jesus have in mind the tradition of preserving of leavening agent, while speaking of the Pharisees' Yeast? The type parameter specifies the hashing algorithm. # File ext/openssl/lib/openssl/pkey.rb, line 343, export([cipher, pass_phrase]) PEM-format String, private_decrypt(string) String, private_decrypt(string, padding) String, # File ext/openssl/lib/openssl/pkey.rb, line 435, private_encrypt(string) String, private_encrypt(string, padding) String, # File ext/openssl/lib/openssl/pkey.rb, line 372, # File ext/openssl/lib/openssl/pkey.rb, line 394, # File ext/openssl/lib/openssl/pkey.rb, line 415, # File ext/openssl/lib/openssl/pkey.rb, line 327, sign_pss(digest, data, salt_length:, mgf1_hash:) String, to_pem([cipher, pass_phrase]) PEM-format String, to_s([cipher, pass_phrase]) PEM-format String, verify_pss(digest, signature, data, salt_length:, mgf1_hash:) true | false, # File ext/openssl/lib/openssl/pkey.rb, line 452. Asynchronously computes the hash of a stream using the SHA256 algorithm. CryptoJS is a growing collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns. Defaults to true. This gives great flexibility (since clients can have multiple requests pending at a time), but it also adds complexity. :user_known_hosts_file => the location of the user known hosts file. This hash can then be used to verify the integrity of the original input, since any change to the input will produce a different hash. Classes: AuthenticationFailed, Buffer, ChannelOpenFailed, ChannelRequestFailed, Config, ConnectionTimeout, Disconnect, Exception, HostKeyError, HostKeyMismatch, HostKeyUnknown, HostKeys, KeyFactory, KnownHosts, Packet, Prompt, Timeout, Version. In Ruby we can use the SHA-256 hash algorithm using the digest library. Defaults to 3, :kex => the key exchange algorithm (or algorithms) to use, :keys => an array of file names of private keys to use for publickey and hostbased authentication, :keycerts => an array of file names of key certificates to use. Reverse lookup, unhash, decode, or "decrypt" MD5 (128 bit) . The most famous block ciphers are determined by the American standard DES (Data Encryption Standard), for which the block length n is 64 and 256, respectively. # is present, so that this works with both new and existing records. However, # when there is an error, the message is added to the password attribute instead. Raw encrypt_decrypt.rb require 'openssl' class String def encrypt(key) cipher = OpenSSL :: Cipher.new('DES-EDE3-CBC').encrypt cipher.key = Digest :: SHA1.hexdigest key s = cipher.update(self) + cipher.final s.unpack('H*')[0].upcase end def decrypt(key) Learn more about bidirectional Unicode characters. The hashlib gives the following cryptographic hash functions to discover the hash output of a text as follows: sha3_224 - 28 bit Digest-Size. But be careful, if you use character sets and combinations, it may take minutes to hours to decrypt a hash and it uses sources of your computer significantly for computation/iteration. The MD5 message-digest algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed as a 32 digit hexadecimal number. A format is an object with two methods stringify and parsethat converts between CipherParams objects and ciphertext strings. Public Class Methods generate (size) => RSA instance click to toggle source generate (size, exponent) => RSA instance 1. password_encryption = scram-sha-256. dCode uses word databases whose hash has already been calculated (several million potential passwords) and checks if the hash is known. You can disable deterministic encryption by omitting a deterministic_key. It offers a more secure solution and stronger for collusion attacks. For more information about the format of arg see "Pass Phrase Options" in openssl (1). When you pass a string, it's automatically converted to a WordArray encoded as UTF-8. . Commit, do not mess with Rakefile, version, or history: if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull). Triple DES applies DES three times to each block to increase the key size. These four functions were designed to be more secure and efficient than the older SHA-1 standard, and were intended for use in a wide range of applications, including digital signatures, data integrity checks, and password storage. SHA-3. Why hasn't the Attorney General investigated Justice Thomas? Got it working with PHP: php -r 'echo base64_encode (hash ("sha256", "asdasd", false));'. Notes on patches/pull requests :timeout => how long to wait for the initial connection to be made. I made a mistake when I named this implementation SHA-3. PBKDF2 is a password-based key derivation function. The hashing functions included in Rubys digest include: MD5, RIPEMED-160, SHA1, and SHA2. The significance of SHA256 is that SHA-256 stands for Secure Hash Algorithm 256-bit and it's used for cryptographic security. SHA-256 is considered to be very secure and is one of the most widely-used hash functions in the world. Sessions are always initiated via Net::SSH.start. DES is now considered to be insecure due to the small key size. :keepalive_maxcount => the maximun number of keepalive packet miss allowed. :fingerprint_hash => MD5 or SHA256, defaults to SHA256, If user parameter is nil it defaults to USER from ssh_config, or local username. If called with a String, tries to parse as DER or PEM encoding of an RSA key. decrypt a SHA256 hash; given the hash, a list of words it could be, and organized as 4, 5, 4, 5, 4. Consider using your key as cipher password and generate a secure random key. If it is not known or combined with salting the decryption will probably fail. If cipher and pass_phrase are given they will be used to encrypt the key. How can I make inferences about individuals from aggregated data? I have not verified but see this stackOverflow post. key = 'my-secret-key' SHA-256 is one of the four variants in the SHA-2 set.
