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
