blkcipher is obsolete and will be removed soon.  So if you are
going to write this then please document skcipher instead.

Also not mentioned in the documentation is that some algorithms *do*
have different implementations depending on key size.  SHA-2 is the
classic example.

What do you mean by that? SHA has no keying at all.
