A Common Lisp interface to OpenSSL.
This library is a fork of SSL-CMUCL. The original SSL-CMUCL source code was written by Eric Marsden and includes contributions by Jochen Schmidt. Development into CL+SSL was done by David Lichteblau. License: MIT-style.
Distinguishing features: CL+SSL is portable code based on CFFI and gray streams. It defines its own libssl BIO method, so that SSL I/O can be written over portable Lisp streams instead of bypassing the streams and sending data over Unix file descriptors directly. (But the traditional approach is still used if possible.)
