Crypt::Blowfish_PP Description

Crypt::Blowfish_PP - blowfish encryption algorithm implemented purely in Perl. Crypt::Blowfish_PP - blowfish encryption algorithm implemented purely in Perl.SYNOPSISuse Crypt::Blowfish_PP;$blowfish=new Crypt::Blowfish_PP($key);$ciphertextBlock=$blowfish->encrypt($plaintextBlock);$plaintextBlock=$blowfish->decrypt($ciphertextBlock);The Crypt::Blowfish_PP module provides for users to use the Blowfish encryption algorithm in perl. The implementation is entirely Object Oriented, as there is quite a lot of context inherent in making blowfish as fast as it is. The key is anywhere between 64 and 448 bits (8 and 56 bytes), and should be passed as a packed string. The transformation itself is a 16-round Feistel Network, and operates on a 64 bit block.Object methods for the Crypt::Blowfish_PP module:new(key)The new() method initialises a blowfish object with the key that is passed. This is the slow part of doing a blowfish encryption or decryption, as it initialises the 18 p-boxes and the 1024 s-boxes that are used for the algorithm. It will return undef if the key is not of a valid length.encrypt(block)The encrypt() method uses the initialised blowfish object to encrypt 8 bytes of data of the string passed to it. It returns the encrypted block.decrypt(block)The decrypt() method uses the initialised blowfish object to decrypt 8 bytes of data of the string passed to it. It returns the decrypted block.
