Signatures over any other digest are considered acceptable. Despite SHA-1 being a mandatory-to-implement digest algorithm in RFC 4880, the collision-resistance of SHA-1 is weaker than anyone would like it to be. Some operators of high-value targets that depend on OpenPGP signatures may wish to require their signers to use a stronger digest algorithm than SHA1, even if the OpenPGP ecosystem at large cannot deprecate SHA1 entirely today. This changeset adds a new "--weak-digest DIGEST" option for both gpg and gpgv, which makes it straightforward for anyone to treat any signature or certification made over the specified digest as unreliable. This option can be supplied multiple times if the operator wishes to deprecate multiple digest algorithms, and will be ignored completely if the operator supplies --allow-weak-digests (as before).
