Blowfish is an encryption algorithm that can be used as a replacement for the DES or IDEA algorithms. Blowfish was designed in 1993 by Bruce Schneier as an alternative to existing encryption algorithms. Designed with 32-bit instruction processors in mind, it is significantly faster than DES. Since ...

Security considerations on using key derivation to create one-time keys for block ciphers

I'm planning to do some block encryption with AES and Blowfish (both with 256 Bit keys) chained. Master key generation: A 32 byte long persistent (over many years) master key is derived from a ...
