It can decreasing the size of the "s-box" and therefore designing and implementing it on a neural network (NN). The Blowfish algorithm is one of the most popular, but it needed essential computational power with some elements that create them prey too many attackers. It is same as in structure to CAST-128, which needs fixed S-boxes. It is a 16-round Feistel cipher and need large key-dependent S-boxes. And in order for the text to be decoded on the other side of transmission, the function should also make a key to unlock the cipher-text.īlowfish is also one of the quickest block ciphers in public use, creating it ideal for a product such as SplashID that functions on a broad variety of processors discovered in cellular phones and in notebook and desktop computers.īlowfish has a 64-bit block size and a key length of anywhere from 32 bits to 448 bits. It implements this routine on chunks of text known as blocks. Blowfish is contained in a huge number of cipher suites and encryption products, such as SplashID.Ī block cipher is generally a computer routine that takes some amount of plain text and transform it into coded text, or cipher-text. The sensitive information and the symmetric encryption key are used within the encryption algorithm to turn the sensitive information into ciphertext. Symmetric encryption uses an individual encryption key to both encrypt and decrypt information. Blowfish is a keyed, symmetric cryptographic block cipher invented by Bruce Schneier in 1993 and located in the public domain. The Blowfish encryption algorithm is a symmetric block cipher designed to achieve in the DES algorithm that was slow and uncertain.
