[CryptoAPI-devel] update: cipher feedback, test_cipher

[David B. <db...@du...>]

I commited cipher feedback mode today.  It allows a block cipher to turn
into a stream cipher, useful for network encryption.  I also modified
test_cipher in the cryptoapi-test module so that it would be easy for me
to test different block modes.
I added the -t flag, which lets you not enter cipher text to the test
parameters.  It then takes the key, plaintext and does
E(k,p)->c->D(k,c)->p.  Then checks to see if the plaintext at the end is
the same as what it was given.  I also updated the docs on it, so that it
prints *slighty* more helpful -h option ;-) with descriptions of what the
optons do.
