mzcrypto

mzcrypto is a crypto library for PLT scheme (aka mzscheme), based on libcrypto.
It provides a fairly complete interface to libcrypto primitives: digests, ciphers, public key cryptography, and Diffie-Hellman key exchange.
The library is available under the GNU LGPL.

Workaround for ffi/provide bug in 4.1.5

2009-04-27
Fix plt-4.1.5.x unsafe! breakage.
Documentation fixes.

Update for plt-4.x
API changes:

• hash has been renamed to digest.
• Low level incremental functions (digest-update! digest-final! cipher-update! cipher-update!) no longer return two values. They either return a fresh byte-string or the number of bytes written in the target byte string.
• Incremental hmac ops
• Engine support.
• More random ops: random-bytes! pseudo-random-bytes! random-rnd-* for entropy pool control.
• New utility functions: bytes-xor bytes-xor!
