[Pharo-dev] Cloudfork HMAC-SHA256 in System-Hashing
Does it make sense from a license point of view and practical point of view to include the CloudFork HMAC-SHA256 implementation (CFSH256 class) in the System-Hashing package (in where there's already SHA1 and MD5) ?

Can Cloudfork HMAC-SHA256 be easily parameterized with, say, an SHA256 base implementation? Or does it require extra stuff? In the former case I probably wouldn’t add it. In the latter case it’s open for discussion. Personally, I think it belongs into a separate package, not into System-Hashing. Cheers, Max

Re: [Pharo-dev] Cloudfork HMAC-SHA256 in System-Hashing
Max, Yes, it's usable as the SHA1 package already there (without HMAC so). I'm no expert in those stuff but I don't get "SHA256 base implementation". Someone with more knowledge can probably tell ;) Sven, The bare minimum to load it is: Gofer it smalltalkhubUser: 'JanVanDeSandt' project: 'Cloudfork'; package: 'Cloudfork-Common'; package: 'Cloudfork-Pharo-Platform'; load. The implementation is in Cloudfork-Pharo-Platform.

Hello, I added the SHA256 class to Cloudfork a few years ago. The class was mostly copied from the Cryptography [1] project. Cheers, Jan.

Re: [Pharo-dev] Cloudfork HMAC-SHA256 in System-Hashing
And I think it's a good idea to make SHA2 hash functions part of the System-Hashing package!

Re: [Pharo-dev] Cloudfork HMAC-SHA256 in System-Hashing
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.

https://pharo.fogbugz.com/f/cases/13395/Add-SHA256-HashFunction cleaned up, documented, properly packaged. Passes some test vectors. I changed the handling of the empty stream.

Re: [Pharo-dev] Cloudfork HMAC-SHA256 in System-Hashing
Wouldn't it be wonderful if we could install packages from a ticket in the image?
