Comment (by karsten):

 Somewhat related to the `sha1Hex()` example, depending on the descriptor
 we might need more than just one method for returning a descriptor digest:
 sha-1, sha-256, etc.  Of course, we could pick one name per digest
 algorithm.  But maybe we'll also need different encodings, hex vs. base64.
 This can get messy.
