Crypto provides a simple implementation of the Rijndael (now AES) and DES
encryption algorithms as well as the SHA1 and SHA2 hashing algorithms. The
library is almost a verbatim copy of the code from OpenBSD and PuTTY for use by
the SDL-Hercules-390 emulator.
The sdl-crypto-devel package contains libraries and header files for
developing applications that use sdl-crypto.
