filter - Joins keys into a keyring applying a filter

Joins keys into a keyring applying a filter

This can be used to filter keys based on given predicates, e.g. whether they have a user id containing an email address with a certain domain. Additionally, the keys can be pruned to only include components matching the predicates.

If no filters are supplied, everything matches.

If multiple predicates are given, they are or'ed, i.e. a key matches if any of the predicates match. To require all predicates to match, chain multiple invocations of this command. See EXAMPLES for inspiration.

Writes to FILE or stdout if omitted
Case-sensitively matches on the user id, requiring an exact match.
Parses user ids into name and email and case-sensitively matches on the name, requiring an exact match.
Parses user ids into name and email address and case-sensitively matches on the email address, requiring an exact match.
Parses user ids into name and email address and case-sensitively matches on the domain of the email address, requiring an exact match.
Matches on both primary keys and subkeys, including those certificates that match the given fingerprint or key id.
Removes certificate components not matching the filter
Emits binary data
Converts any keys in the input to certificates. Converting a key to a certificate removes secret key material from the key thereby turning it into a certificate.

Reads from FILE or stdin if omitted
