7. RE: how to disable pinentry (Smith, Cathy)

[Rob Fries]

Hi Cathy,

We use /usr/libexec/gpg-preset-passphrase to set our passphrase. 

 /usr/libexec/gpg-preset-passphrase  -cP "$passphrase" $keygrip

  You would need to add this to your .gpg-agent.conf:

allow-preset-passphrase

you will need to get the KEYGRIP. The easiest way I found is:

gpg2 --fingerprint --fingerprint --list-secret-keys | grep "fingerprint" | cut -d= -f2 | tr -d ' '

make sure you get the correct one for the correct key( note the above command shows double the number of keygrips for what you need.. ).
	
and you may want to adjust your max-cache-ttl gpg-agent.conf too.  If you want to forget a passphrase before the ttl is up, you can use gpg-preset-passphrase to forget it.

Rel6 does provide a pinentry-curses program:

/usr/bin/pinentry-curses


Hope that helps!

Adding this line didn't work:
	pinentry-program /usr/bin/pinentry-tty

The message was invalid option
	gpg: /home/foo/.gunpg/gpg.conf:242:  invalid option

The CentOS6 and RHEL6 distributions don't  provide a /usr/bin/pinentry-tty.   

One of my goals of this is to be able to set a passphrase on a key in batch processing.  Perhaps, there is another way to accomplish that?


Thank you

Cathy
