But if they are to be added to the Crypto module, they should be fixed to follow the same API as the other hash functions though. I think that'd be preferable regardless where in Pike they're added, as well. Besides, the naming convention for functions in Pike is_like_this, and notthisway.
If there is a consensus about adding the module to Crypto I'd happily adapt the module to be more like other hash functions, and follow naming conventions better.
