I've put up the beginnings of a wrapper for OpenSSL on STH:
Metacello new baseline: 'OpenSSL'; smalltalkhubUser: 'PierceNg' project: 'OpenSSL-Pharo'; load.
Verified on Pharo 6 32- and 64-bit.
My near term goal is to wrap enough libcrypto functionality to implement the client-side of Let's Encrypt.
I meant to put it up on GH, for the ease of forking and PRs, but I couldn't get Iceberg to work, and gitfiletree also failed to load, so STH it is for now.
