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

Print the session key to stderr
Write to FILE or stdout if omitted
[default: -]
Decrypt the message using the key in KEY_FILE
Decrypt an encrypted message using SESSION-KEY
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]
Verify signatures using the certificates in CERT_FILE
Read from FILE or stdin if FILE is '-'
[default: -]

Global options

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