+# This is a pure python implementation of the DES encryption algorithm.
+# It's pure python to avoid portability issues, since most DES
+# implementations are programmed in C (for performance reasons).
+#
+# Triple DES class is also implemented, utilizing the DES base. Triple DES
+# is either DES-EDE3 with a 24 byte key, or DES-EDE2 with a 16 byte key.
+#
+# See the README.txt that should come with this python module for the
+# implementation methods used.
+#
+# Thanks to:
+# * David Broadwell for ideas, comments and suggestions.
+# * Mario Wolff for pointing out and debugging some triple des CBC errors.
+# * Santiago Palladino for providing the PKCS5 padding technique.
+# * Shaya for correcting the PAD_PKCS5 triple des CBC errors.

+"""A pure python implementation of the DES and TRIPLE DES encryption algorithms.
+
+Class initialization
+--------------------
+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 bytes
+ for Triple DES
+mode -> Optional argument for encryption type, can be either
+ pyDes.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 during
+ all encrypt/decrypt operations done with this instance.
+padmode -> Optional argument, set the padding mode (PAD_NORMAL or PAD_PKCS5)
+ to use during all encrypt/decrypt operations done with this instance.
+
+I recommend to use PAD_PKCS5 padding, as then you never need to worry about any
+padding issues, as the padding can be removed unambiguously upon decrypting
+data that was encrypted using PAD_PKCS5 padmode.
+
+Common methods
+--------------
+encrypt(data, [pad], [padmode])
+decrypt(data, [pad], [padmode])
+
+data -> Bytes to be encrypted/decrypted
+pad -> Optional argument. Only when using padmode of PAD_NORMAL. For
+ encryption, adds this characters to the end of the data block when
+ data is not a multiple of 8 bytes. For decryption, will remove the
+ trailing characters that match this pad character from the last 8
+ bytes of the unencrypted data block.
+padmode -> Optional argument, set the padding mode, must be one of PAD_NORMAL
+ or PAD_PKCS5). Defaults to PAD_NORMAL.
+
+
+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
+
+
+See the module source (pyDes.py) for more examples of use.
+You can also run the pyDes.py file without and arguments to see a simple test.
+
+Note: This code was not written for high-end systems needing a fast
+ implementation, but rather a handy portable solution with small usage.
