I hate to say it, but RTFM applies.
'apropos encryption' gives, among other things (and first), a cite to bdes(1).

'bdes' is a program that comes with the FreeBSD distribution.
You have access to the source code of all of the distribution.

'Use the Souce, Luke" applies, and will bring the mountain to Mohammad. :)
