VERSION 2a:
11 Aug 2003
- Only very minor changes. The makefile was tweaked slightly
for increased portability, and a typo in lock_strip was fixed.
VERSION 2:
10 Aug 2003
- Replaced the SHA-1 library with the source code from RFC 1374.
The old code had problems on PowerPC that I was too lazy to hunt
down and fix.
- Replaced the ISC version of Base64 with an implementation
produced by Sweden's Royal Institute of Technology (KTH). The
old functions carried a weird patent disclaimer from IBM, while
the new ones use a nice simple non-scary BSD license.
- The md5_key(), md5_lock() and md5_verify() functions have been
removed. As far as I can tell they weren't being used.
- Added a Makefile instead of the Build thingy.
- Did a bunch of cleanup to get rid of various warnings.
VERSION 1:
24 Sep 1998
- Now trying to be compatible with an updated cancel lock draft.
- We now generate the lock by hashing the Base64 encoding of the
cancel key, instead of the underlying binary digest.
- the xxx_key() and xxx_lock() functions now add the md5: or sha1:
tag to the lock.
- lock_strip_alpha() now discards pesky clue strings and normalizes
the case of type codes.
- the old lock_strip() that returned numeric codes will be going
away.
VERSION 0:
21 Sep 1998
- Endianness is now automatically figured out by build.
19 Sep 1998
- Added MD5 hashes.
- We now accommodate the possibility that strings will be identified
by name instead of number, those darned drafts will get you every
time.
- Make changes to the hmac stuff to account for GCC weirdness; some
check values were not coming out correctly, but they are now.
15 Sep 1998
- Initial, just SHA-1.
