Password for keyring

[Mohan Radhakrishnan]

Hi,
        We use passphrases for protecting the secret key. Is there a
passphrase for accessing the keyring itself ?

Thanks,
Mohan

You only need a passphrase when signing or decrypting unless your using
symmetric encryption.

The man page documents the following options:

       --passphrase-fd n
                 Read  the  passphrase from file descriptor n.  Only the
first
                 line will be read from file descriptor n.  If you use
0  for
                 n,  the passphrase will be read from stdin.  This can
only be
                 used if only one passphrase is supplied.

       --passphrase-file file
                 Read the passphrase from file file.  Only the first
line will
                 be  read  from  file file.  This can only be used if
only one
                 passphrase is supplied.  Obviously, a passphrase stored
in  a
                 file is of questionable security if other users can
read this
                 file.  Don't use this option if you can avoid it.

       --passphrase string
                 Use string as the passphrase.  This can only be used if
only
                 one passphrase is supplied.  Obviously, this is of very
ques-
                 tionable security on a multi-user  system.   Don't  use
this
                 option if you can avoid it.
