python的des和3des加解密

1.加密：

pyDes.des(key, [mode], [IV], [pad], [padmode]) pyDes.triple_des(key, [mode], [IV], [pad], [padmode])key -> Bytes containing the encryption key. 8 bytes for DES, 16 or 24 bytesfor Triple DES mode -> Optional argument for encryption type, can be eitherpyDes.ECB (Electronic Code Book) or pyDes.CBC (Cypher Block Chaining) IV -> Optional Initial Value bytes, must be supplied if using CBC mode.Length must be 8 bytes. pad -> Optional argument, set the pad character (PAD_NORMAL) to use duringall encrypt/decrpt operations done with this instance. padmode -> Optional argument, set the padding mode (PAD_NORMAL or PAD_PKCS5)to use during all encrypt/decrpt operations done with this instance.

实例：

Example ------- from pyDes import *data = "Please encrypt my data" k = des("DESCRYPT", CBC, "\0\0\0\0\0\0\0\0", pad=None, padmode=PAD_PKCS5) # For Python3, you'll need to use bytes, i.e.: # data = b"Please encrypt my data" # k = des(b"DESCRYPT", CBC, b"\0\0\0\0\0\0\0\0", pad=None, padmode=PAD_PKCS5) d = k.encrypt(data) print "Encrypted: %r" % d print "Decrypted: %r" % k.decrypt(d) assert k.decrypt(d, padmode=PAD_PKCS5) == data
