Maybe we could use just "SHA-1" if a single algorithm is used for everything, and both "SHA-1 for crypto" and "SHA-1 for non-crypto" otherwise. Related to this I wonder if we should warn in some ways if a non collision detection algorithm is used for crypto. For example we could print "SHA-1: OpenSSL (No collision detection!!!)" instead of just "SHA-1: OpenSSL". And yeah that should be documented. Thanks!
