db5b10fab5 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.

fa5846e58b 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.

4ed9388e5d A new branch for FIPS-related changes has been created with the name 
OpenSSL-fips-0_9_7-stable.

Since the 0.9.7-stable branch is supposed to be in freeze and should
only contain bug corrections, this change removes the FIPS changes
from that branch.

dbcc560717 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.

ff90d659e6 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

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.
