[IronPython] md5 for IronPython

[Keith J. Farmer]

Which is why I suggested an overload.  Enums protect against spelling mistakes that strings, while flexible, promote.  With an overload you can use either, preferring the enum for the compile-time assist (and as an indication that perhaps the user wants to use the framework implementation of SHA, for example).

The reason we use a string is that it's actually a fully pluggable framework.  For instance, someone in the NSA could have a top-secret hash algorithm that we didn't put into the framework.  They could implement it themselves, register it in machine.config, and then do HashAlgorithm.Create("SuperSecretNSAHash") and it would work.

Unless I'm lacking sleep and miss something (likely), you could make an
overload that took an enum, such as the pre-existing ones in the
framework.

If you wanted to easily extend it to other algorithms, then instead of
using MD5.Create() in your __init__, you could instead do
HashAlgorithm.Create("MD5").

That allows you to swap in any hash algorithm you'd like (and that the
framework supports) just by swapping the string.
