> the shaX functions do that perfectly. The SHA-2 family (namely SHA-224, SHA-256, SHA-384, SHA-512) are good candidates, and probably SHA-3 too. Let's stop recommending and start phasing out SHA-1 (and definitely never use SHA-0); nobody's demonstrated a collision yet, but it could well be coming. SHA-1 has been deprecated by NIST since 2010; new applications shouldn't use it.
