The key is either specified as a +fingerprint or a file listing fingerprints. The fingerprint must be +given or listed in compact format (no colons or spaces in between). +As of now only SHA-1 fingerprints are allowed. This option can be +given multiple times and each fingerprint is checked against the +signing key as well as the corresponding primary key. If +@var{fpr_or_file} specifies a file, empty lines are ignored as well as +all lines starting with a hash sign.
