Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Version history

3.2.0
Add raw-update. Kon Lovett
3.1.0
Add block-length. Kon Lovett
3.0.0
Remove deprecated procedures. Kon Lovett
2.5
Make function declarations static in order to avoid conflicts with those from libc if the OS supplies them. This makes MD5 work on OpenBSD (thanks to Alan Post and Christian Kellermann)
2.4
Change deprecated pointer foreign type specifier to scheme-pointer to make it work under chickens newer than 4.6.0.
2.3
Do not define uint32 as uint32_t but use it directly to avoid conflicts with system-defined types on some OSes.
2.2
a message-digest-primitive has no "state". Kon Lovett
2.1
Fixed typo in setup file that caused the extension to get installed under the name "m5"
2.0
Chicken 4 implementation. Replaced GPL code with common public domain code.
1.1
Added dependency on message-digest egg
1.0
Initial release
