NAME

       sq-keyring-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.

SYNOPSIS

       sq keyring filter [FLAGS] [OPTIONS] [--] [FILE]

FLAGS

       -h, --help
              Prints help information

       -P, --prune-certs
              Removes certificate components not matching the filter

       -B, --binary
              Emits binary data

       --to-cert
              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.

OPTIONS

       -o, --output FILE
              Writes to FILE or stdout if omitted

       --name NAME
              Matches on NAME

       --email ADDRESS
              Matches on email ADDRESS

       --domain FQDN
              Matches on email domain FQDN

ARGS

       FILE   Reads from FILE or stdin if omitted

EXAMPLES

       # Converts a key to a cert (i.e., remove any secret key material)
              $ sq keyring filter --to-cert cat juliet.pgp

       # Gets the keys with a user id on example.org
              $ sq keyring filter --domain example.org keys.pgp

       # Gets the keys with a user id on example.org or example.net
              $ sq keyring filter --domain example.org --domain example.net keys.pgp

       # Gets the keys with a user id with the name Juliet
              $ sq keyring filter --name Juliet keys.pgp

       # Gets the keys with a user id with the name Juliet on example.org
              $ sq keyring filter --domain example.org keys.pgp | keyring filter --name Juliet

       # Gets the keys with a user id on example.org, pruning other userids
              $ sq keyring filter --domain example.org --prune-certs certs.pgp
