Hi Ian, > I agree with all the rest, but can we also deprecate some old stuff as > well? > > Can we construct a plan e.g., that no existing S2K be used with new > keys and the new form not be used with old keys? I have made salt-based methods mandatory in my patch: > +Implementations MUST generate S2K specifiers that include salts > +(either type 2, 3 or 4), as simple S2K specifiers are more vulnerable to (type 2 should actually be "type 1") > +dictionary attacks. Use of Argon2i is RECOMMENDED as it offers > +protection against massive-parallel and side-channel attacks. When > +reading S2K specifiers that do not include salts, implementations SHOULD > +issue a warning about potentially insecure methods being used. When > +reading S2K specifiers other than Argon2i, implementations SHOULD issue > +a warning about outdated methods being used. We can of course raise the bar by excluding types 1 & 3 entirely.
