[Pharo-dev] Bitmap VS WordArray in System-Hashing

Hi, With Max M., we try to kill the dependency between System-Hashing to Graphics - Display Objects. The dependency is there because SHA1 and SHA256 use the Bitmap class to store raw data. We came to replace the use of Bitmap by a WordArray. Tests are still working. Could someone tell us if this fix is right or if we miss something? Thanks, Max and Christophe
