NAME

       verify - Verifies signed messages or detached signatures

SYNOPSIS

       verify [-o|--output] [--detached] [-n|--signatures] [--signer-cert] [-h|--help] [FILE]

DESCRIPTION

       Verifies signed messages or detached signatures

       When  verifying  signed  messages,  the  message is written to stdout or the file given to
       --output.

       When a detached message is verified, no output is produced.  Detached signatures are often
       used to sign software packages.

       Verification  is  only  successful  if  there  is  no  bad  signature,  and  the number of
       successfully verified signatures reaches the threshold configured with the  "--signatures"
       parameter.   If  the  verification  fails,  the  program  terminates  with  an exit status
       indicating failure.  In addition to that, the last 25 MiB of  the  message  are  withheld,
       i.e.  if  the  message is smaller than 25 MiB, no output is produced, and if it is larger,
       then the output will be truncated.

       The converse operation is "sq sign".

OPTIONS

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

       --detached=SIG
              Verifies a detached signature

       -n, --signatures=N [default: 1]
              Sets the threshold of valid signatures to N. If this threshold is not reached,  the
              message will not be considered verified.

       --signer-cert=CERT
              Verifies signatures with CERT

       -h, --help
              Print help information

       [FILE] Reads from FILE or stdin if omitted

EXAMPLES

        Verify a signed message

               sq verify --signer-cert juliet.pgp signed-message.pgp

        Verify a detached message

               sq verify --signer-cert juliet.pgp --detached message.sig message.txt
       SEE  ALSO:  If  you  are  looking  for a standalone program to verify detached signatures,
       consider using sequoia-sqv.
