gnupg: gpg-preset-passphrase

 
 9.6 Put a passphrase into the cache
 ===================================
 
 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.
 
    This program works with GnuPG 2 and later.  GnuPG 1.x is not
 supported.
 
    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).  Note that
 the maximum cache time as set with '--max-cache-ttl' is still honored.
 It is necessary to allow this passphrase presetting by starting
 'gpg-agent' with the '--allow-preset-passphrase'.
