Blowfish The Blowfish algorithm is a symmetric encryption and block cipher, making it highly secure. It is a fast encryption algorithm that takes a variable-length key, making it accessible for exportation. Blowfish converts the messages into ciphertext using a specific key. This key takes much ...
For more information on the syntax for configuring the algorithm choices, see thepolicy.conf(4)man page. Example—Using the Blowfish Algorithm for Password Encryption In this example, the identifier for the Blowfish algorithm,2a, is specified as the value for theCRYPT_DEFAULTvariable. Thepolicy.co...
How public key encryption works A cryptographic key is a mathematical algorithm implemented in software or hardware and used to encrypt or decrypt data. It is a string of bits that are combined with the data to createciphertext. The cryptographic key can also be used to unencrypt data back t...
Encryption is the process of converting information or data into a code to prevent unauthorized access. Learn how it works now.
Bcrypt is a cryptographic hash function based on the Blowfish block cipher. It was created mainly for the purpose of hashing static passwords, unlike other known functions for hashing arbitrary binary data. Thanks to the use of salt, it’s resistant to rainbow table attacks. It allows you to...

The MD5 hashing algorithm and how it works in cryptography. Some of the most popular cryptographic hashes include the following: SHA-2. SHA-3. The series of message-digest hash functions: MD2, MD4, MD5 and MD6. Message-digest hash functions such as MD2, MD4 and MD5 hash digital signatu...
IDEA (International Data Encryption Algorithm) Blowfish (Drop-in replacement for DES or IDEA) RC4 (Rivest Cipher 4) RC5 (Rivest Cipher 5) RC6 (Rivest Cipher 6) Asymmetric Encryption is newer and more secure but needs a lot more processing power, making it much slower than Symmetric Encryption...
Symmetric encryption algorithmuses the same key to encrypt plaintext and decrypt ciphertext. Both the sender and receiver must have the same key in order to communicate with each other. Examples of this type of algorithm or cipher includeAdvanced Encryption Standard (AES)andBlowfish. TheNational In...
