Hash.toString

Encodes the digest, salt and hash into a convenient forward-compatible string format, ready for insertion into a database.

To support additional digests besides the built-in (Phobos's CRC32, MD5, RIPEMD160 and SHA), supply a custom delegate for digestCodeOfObj. Your custom digestCodeOfObj only needs to handle OO-style digests. As long as the OO-style digests were created using Phobos's WrapperDigest template, the template-style version will be handled automatically. You can defer to DAuth's defaultDigestCodeOfObj to handle the built-in digests.
