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
