Thats because it is a "password module" and nobody or a small
percentage of the population uses CRC for password digest.
In turn, that's because CRC is not not a crytographic hash and
not suited for password hashing :)
The basic point is that std.digest/std.hash (whatever people
decide) should probably just have generic digesting algorithm.
Generic digesting algorithm should probably go into std.algorithm.
It could be used like that:
------------
import std.algorithm;
import std.checksum;
import std.crypto.mdc;
ushort num = 1234;
auto hash1 = hash!("(a >>> 20) ^ (a >>> 12) ^ (a >>> 7) ^ (a >>>
4) ^ a")(str); // indexing hash
string str = "abcd";
auto hash3 = hash!(CRC32)(str); // checksum
auto hash2 = hash!(MD5)(str); // crytographic hash
------------
CRC32 and MD5 are ranges and/or classes, derived from
HashAlgorithm interface.
