4e952ae4fc Removing those memcpy()s also took away the possibility for in and out to
be the same.  Therefore, the removed memcpy()s need to be restored.

0b6956b474 Correct serious bug in AES-CBC decryption when the message length isn't
a multiple of AES_BLOCK_SIZE.
Optimize decryption of all complete blocks in AES-CBC by removing an
unnecessary memcpy().

The error was notified by James Fernandes <jf210032@exchange.DAYTONOH.NCR.com>.
The unnecessary memcpy() was found as an effect of investigating that error.

61f00386ab The counter is big-endian. Since it comes as an array of char,
there's absolutely no need to special-case it on little-endian
machines.

1729588435 The AES CTR API was buggy, we need to save the encrypted counter as well
between calls, or that will be lost if it returned with *num non-zero.

001ab3abad Use double dashes so makedepend doesn't misunderstand the flags we
give it.
For 0.9.7 and up, that means util/domd needs to remove those double
dashes from the argument list when gcc is used to find the
dependencies.

f6fbd470e3 It looks like I didn't remove everything that has to do with the

72165799a8 There is no aestest currently. The EVP tester is used to check the
AES algorithm.

e4dd79bbc8 - Add the same header stuff to aes_locl.h as is in des_locl.h to avoid
undefined functions (memset, etc).
- Put a .cvsignore in the aes directory too.

6f9079fd50 Because Rijndael is more known as AES, use crypto/aes instead of
crypto/rijndael.  Additionally, I applied the AES integration patch
from Stephen Sprunk <stephen@sprunk.org> and fiddled it to work
properly with the normal EVP constructs (and incidently work the same
way as all other symmetric cipher implementations).

This results in an API that looks a lot like the rest of the OpenSSL
cipher suite.
