NAME

       sq sign - Sign messages or data files

SYNOPSIS

       sq sign [OPTIONS] FILE

DESCRIPTION

       Sign messages or data files.

       Creates  signed  messages  or  detached  signatures.  Detached signatures are often used to sign software
       packages.

       The converse operation is `sq verify`.

       `sq sign` respects the reference time set by the top-level `--time` argument.   When  set,  it  uses  the
       specified  time  instead  of  the  current  time,  when  determining what keys are valid, and it sets the
       signature's creation time to the reference time instead of the current time.

OPTIONS

   Subcommand options
       -B, --binary
              Emit binary data

       -a, --append
              Append a signature to existing signature

       --cleartext-signature
              Create a cleartext signature

       --detached
              Create a detached signature

       --merge=SIGNED-MESSAGE
              Merge signatures from the input and SIGNED-MESSAGE

       -n, --notarize
              Sign a message and all existing signatures

       --notation NAME VALUE
              Add a notation to the  certification.   A  user-defined  notation's  name  must  be  of  the  form
              `name@a.domain.you.control.org`.  If  the  notation's name starts with a `!`, then the notation is
              marked as being critical.  If a consumer of a signature doesn't understand  a  critical  notation,
              then it will ignore the signature.  The notation is marked as being human readable.

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

       --private-key-store=KEY_STORE
              Provide parameters for private key store

       --signer-file=KEY_FILE
              Sign the message using the key in KEY_FILE

       --signer-key=KEYID|FINGERPRINT
              Sign the message using the specified key on the key store

        FILE  Read from FILE or stdin if omitted

   Global options
       See sq(1) for a description of the global options.

EXAMPLES

       Create a signed message

              sq sign --signer-file juliet.pgp message.txt

       Create a detached signature

              sq sign --detached --signer-file juliet.pgp message.txt

       Create a signature with the specified creation time

              sq sign --time 20020304 --detached --signer-file juliet.pgp \
                     message.txt
