NAME

       sq-verify - 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".

SYNOPSIS

       sq verify [FLAGS] [OPTIONS] [--] [FILE]

FLAGS

       -h, --help
              Prints help information

OPTIONS

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

       --detached SIG
              Verifies a detached signature

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

       --signer-cert CERT
              Verifies signatures with CERT

ARGS

       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
