# This is a pure python implementation of the DES encryption algorithm.

# It's pure python to avoid portability issues, since most DES

|

#
|
||||
# Triple DES class is also implemented, utilising the DES base. Triple DES
|

# is either DES-EDE3 with a 24 byte key, or DES-EDE2 with a 16 byte key.

# * Mario Wolff for pointing out and debugging some triple des CBC errors.

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/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.
|
||||
|
||||
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.
