Blowfish, developed in 1993 by Bruce Schneier, is a symmetric encryption method that is characterized by a fast and very secure algorithm, especially in conjunction with 32-bit computers.

The Blowfish method works with a block length of 64 bits and a variable key length of 32 bits to 448 bits.

Blowfish is very efficient and works with XOR operations and addition 32-bit words. It is considered secure and has significant advantages over other symmetric methods such as the Data Encryption Standard( DES), Triple DES( 3DES) and the International Data Encryption Algorithm( IDEA) and can be used without licenses. Blowfish's successor, introduced in 1998, is Twofish.
