[Pharo-dev] [ANN] sha256 checksum for Pharo6 downloads

Hi Marcus,

Are you using SHA256 inside Pharo to generate the checksum files? If so were you planning to use the OpenPGP by hmmosner, in the Cryptography repository for PGP signatures?

I am curious as to integration of the newest Cryptography package there into Pharo. There are two Undeclared: SoundRecorder and FillInTheBlank, though I do not know if such would be a part of a Pharo-Squeak compatibility layer.

More pertinent would be what to do with the HashFunctions that already reside in the Pharo image. If the decision was to include the entire Cryptography into base, then making the HashFunctions not go Obselete would be the objective.

Currently, SHA1, SHA256 and MD5 all get redefined by Cryptography-zzz.111.mcz loading.

What do you think about bringing Cryptography up to date for Pharo and what would be needed. It would help to seek common ground between Squeak and Pharo, yes?
