Yes, if a common package for both Squeak and Pharo is possible, that'd be great. Otherwise, the Squeak and Pharo versions should reside in separate repositories. Squeak users are still using squeaksource.com, Pharo moved to smalltalkhub and beyond..

hey Ron, It was actually the Pharo Cryptography team I was thinking of. Perhaps we can get the same package to work in both squeak and Pharo, with use of installable entropy sources or the like. In order to get SqueakElib running in Pharo I need crypto and we may as well do it right.
