@ -20,6 +20,7 @@ A signature might be correct, but still disqualify as a valid signature.
Put mathematically, the set of valid signatures is a subset of the set of correct signatures.
The validity of a correct signature is additionally constrained by a number of conditions:
Signatures need to be well-formed, meaning they must contain required signature subpackets in the proper subpacket area and must not contain unknown critical subpackets or notations.
Most signatures have a limited validity period, constrained by the signature creation- and expiration time.
Furthermore, some signatures need to be *qualified* by another valid signature in order to be considered valid.
Lastly, signatures can be invalidated by revocations.
