ctrl+a is seen as ctrl+home windows

by Tudor Girba

Hi, I am on Windows, using Pharo 3.0, and I am trying to get the keybindings to work in Rubric using Windows convention (so, Ctrl instead of Cmd as a modifier), It worked reasonably well, but the problem is that somehow Ctrl+a is mapped to Ctrl+Home. The problem is not specific to Rubric as I can detect the same behavior in the regular PluggableTextMorph. Does anyone have an idea of where the problem comes from?

Hi Jan, I loaded just the class CFSHA256 and it worked perfectly (I didn't expect anything else). I tried some examples from Wikipedia (http://en.wikipedia.org/wiki/Sha256#Examples_of_SHA-2_variants) (CFSHA256 hashMessage: 'The quick brown fox jumps over the lazy dog') hex. 'd7a8fbb307d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592' (CFSHA256 hashMessage: 'The quick brown fox jumps over the lazy dog.') hex. 'ef537f25c895bfa782526529a9b63d97aa631564d5d789c2b765448c8635fb6c' So I will rename the class to SHA256, moving it to System-Hashing and add SHA256Tests for starters.
