=> a package developed in squeak [1] that was I think ported/forked for Pharo. I cannot find the Pharo version

=> a binding to the sodium library (NaCl) [2]

With one would you recommend ?  Maybe another option ?

Concerning hashing (I���d like to hash information content a bit like this is done in ifs with their multihash lib [3])

=> I found a keccak implication with I think would do the [4]. Any feedback ? Other implementations available ?

=> Do you think having something like ifs multihash would be interesting in Pharo ?

Again, thanks in advance for your comments/advices.
