2.6.9 Set a passphrase for a keygrip

This command adds a passphrase to the cache for the specified keygrip.

  PRESET_PASSPHRASE [--inquire] <string_or_keygrip> <timeout> [<hexstring>]

The passphrase is a hexadecimal string when specified. When not specified, the passphrase will be retrieved from the pinentry module unless the --inquire option was specified in which case the passphrase will be retrieved from the client.

The timeout parameter keeps the passphrase cached for the specified number of seconds. A value of -1 means infinite while 0 means the default (currently only a timeout of -1 is allowed, which means to never expire it).
