NAME

       sq decrypt - Decrypt a message

SYNOPSIS

       sq decrypt [OPTIONS] FILE

DESCRIPTION

       Decrypt a message.

       Decrypt  a  message  using either supplied keys, or by prompting for a password.  If message tampering is
       detected, an error is returned.  See below for details.

       If certificates are supplied using the `--signer-cert` option, any signatures that are found are  checked
       using  these  certificates.  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 signature verification fails, or if message tampering is detected, 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 encrypt`.

OPTIONS

   Subcommand options
       --dump-session-key
              Print the session key to stderr

       -n, --signatures=N
              Set  the  threshold of valid signatures to N. The message will only be considered verified if this
              threshold is reached. [default: 1 if at least one signer cert file is given, 0 otherwise]

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

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

       --recipient-file=KEY_FILE
              Decrypt the message using the key in KEY_FILE

       --session-key=SESSION-KEY
              Decrypt an encrypted message using SESSION-KEY

       --signer-file=CERT_FILE
              Verify signatures using the certificates in CERT_FILE

        FILE  Read from FILE or stdin if omitted

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