||Use this class to decrypt ciphertext generated by EncryptCBC.
||Use this class to decrypt ciphertext generated by EncryptCFB.
||Use this class to decrypt ciphertext generated by EncryptECB.
||DecryptMode objects are used to decrypt ciphertext generated with
a correpsonding EncryptMode object.
||Use this class to decrypt ciphertext generated by EncryptOFB.
||Cipher Block Chaining mode xors each plain block with the previous
cipher block before encrypting.
||This class implements 8-bit Cipherblock FeedBack mode which encrypts
a whole block for each plaintext character.
||Electronic Codebook Mode simply encrypts each block of plaintext
||Descendants of EncryptMode encrypt arbtrarily large arrays of
||Output Fedback Mode iterates the encryption routine on the IV and xors
the resulting stream with the plaintext to produce the ciphertext.
||This class is used by EncryptOFB and DecryptOFB to precalculate the
