std.hash, when?

[Adam D. Ruppe]

If std.hash doesn't work out for you - though I think it is going 
to be in the next release since the vote passed - I have a sha 1 
function in my sha.d, and a binding to the mhash C library for 
more complex signatures in my oauth.d

Take a look at oauth.d, at the bottom of the file for a function 
called mhashSign.
