Nice work!

For the hashes, I think you should follow the interface of the 
Phobos std.digest package, with `start`, `put` and `finish` 
methods:

http://dlang.org/phobos/std_digest_digest.html

Also, in 2.068 there will be an optional enum `blockSize` (in 
bits) for the hash algorithms, for use with the newly added 
std.digest.hmac. Your library has a runtime method for that. 
Isn't the block size always known at compile time? If you could 
change it to an enum, your library would be compatible with 
Phobos.

Maybe a similar interface should be used for the block ciphers?
