NAME
gpg-preset-passphrase - Put a passphrase into gpg-agent's
cache
SYNOPSIS
gpg-preset-passphrase [options] [command] cache-id
DESCRIPTION
The gpg-preset-passphrase is a utility to seed the internal
cache of a running gpg-agent with passphrases. It is mainly
useful for unattended machines, where the usual pinentry
tool may not be used and the passphrases for the to be used
keys are given at machine startup.
Passphrases set with this utility don't expire unless the
--forget option is used to explicitly clear them from the
cache --- or gpg-agent is either restarted or reloaded (by
sending a SIGHUP to it). It is necessary to allow this
passphrase presetting by starting gpg-agent with the
--allow-preset-passphrase.
gpg-preset-passphrase is invoked this way:
gpg-preset-passphrase [options] [command] cacheid
cacheid is either a 40 character keygrip of hexadecimal
characters identifying the key for which the passphrase
should be set or cleared. The keygrip is listed along with
the key when running the command: gpgsm --dump-secret-keys.
Alternatively an arbitrary string may be used to identify a
passphrase; it is suggested that such a string is prefixed
with the name of the application (e.g foo:12346).
One of the following command options must be given:
--preset
Preset a passphrase. This is what you usually will use.
gpg-preset-passphrase will then read the passphrase
from stdin.
--forget
Flush the passphrase for the given cache ID from the
cache.

The following additional options may be used:
-v
--verbose
Output additional information while running.
-P string
--passphrase string
Instead of reading the passphrase from stdin, use the
supplied string as passphrase. Note that this makes
the passphrase visible for other users.
