WebThe key Expansion of blowfish algorithm begins with the P-array and S-boxes with the utilization of many sub-keys, which requires pre-computation before data encryption or decryption. The P-array consists of eighteen 4 byte sub-keys: P1, P2…P17, P18. Blowfish with keys up to 448 bits length is transformed into several sub-key arrays. WebSymmetric encryption is the process of converting plaintext into ciphertext and vice versa using the same key. An encryption key is a random string of bits used to encrypt or decrypt data. It is, therefore, important that key is transferred between the sender and recipient using secure methods. RC4, RC5, RC6, IDEA, Blowfish, AES, DES and 3DES ...
