des.sage as a patch against Sage 4.4.rc0

comment:2 Changed 11 years ago by mvngu

The patch ​trac_8764-original-des.patch contains essentially the same code as in ​des.sage, but as a patch against the Sage library. The next task is to clean up that patch and organize the cryptography section of the reference manual in light of this implementation of DES.

I have cleaned up the patch a little bit.

There remains one doctest failing, and missing doctests.
