NAME

       decrypt - Decrypts a message

SYNOPSIS

       decrypt      [-o|--output]     [-n|--signatures]     [--signer-cert]     [--recipient-key]
       [--private-key-store] [--dump-session-key] [--session-key] [--dump] [-x|--hex] [-h|--help]
       [FILE]

DESCRIPTION

       Decrypts a message

       Decrypts 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

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

       -n, --signatures=N
              Sets 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]

       --signer-cert=CERT
              Verifies signatures with CERT

       --recipient-key=KEY
              Decrypts with KEY

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

       --dump-session-key
              Prints the session key to stderr

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

       --dump Prints a packet dump to stderr

       -x, --hex
              Prints a hexdump (implies --dump)

       -h, --help
              Print help information

       [FILE] Reads from FILE or stdin if omitted

EXAMPLES
