// BLOWFISH ENCRYPTION ALGORITHM
|
||||
//
|
||||
// encryption and decryption of Byte Strings using the Blowfish encryption Algorithm.
|
||||
// Blowfish is a block cipher that encrypts data in 8-byte blocks. The algorithm consists
|
||||
// of two parts: a key-expansion part and a data-ancryption part. Key expansion converts a
|
||||
// variable key of at least 1 and at most 56 bytes into several subkey arrays totaling
|
||||
// 4168 bytes. Blowfish has 16 rounds. Each round consists of a key-dependent permutation,
|
||||
// and a key and data-dependent substitution. All operations are XORs and additions on 32-bit words.
|
||||
// The only additional operations are four indexed array data lookups per round.
|
||||
// Blowfish uses a large number of subkeys. These keys must be precomputed before any data
|
||||
// encryption or decryption. The P-array consists of 18 32-bit subkeys: P0, P1,...,P17.
|
||||
// There are also four 32-bit S-boxes with 256 entries each: S0,0, S0,1,...,S0,255;
|
||||
// S1,0, S1,1,...,S1,255; S2,0, S2,1,...,S2,255; S3,0, S3,1,...,S3,255;
|
||||
//
|
||||
// The Electronic Code Book (ECB), Cipher Block Chaining (CBC) and Cipher Feedback modes
|
||||
// are used:
|
||||
//
|
||||
// In ECB mode if the same block is encrypted twice with the same key, the resulting
|
||||
// ciphertext blocks are the same.
|
||||
//
|
||||
// In CBC Mode a ciphertext block is obtained by first xoring the
|
||||
// plaintext block with the previous ciphertext block, and encrypting the resulting value.
|
||||
//
|
||||
// In CFB mode a ciphertext block is obtained by encrypting the previous ciphertext block
|
||||
// and xoring the resulting value with the plaintext
|
||||
//
|
||||
// The previous ciphertext block is usually stored in an Initialization Vector (IV).
|
||||
// An Initialization Vector of zero is commonly used for the first block, though other
|
||||
// arrangements are also in use.
