Storing password in keyring

2010-01-22 Thread Mohan Radhakrishnan 
Hi,
 
Question 1 :
 
  Is there any way to store a password in a keyring ? I don't
have a database for this. I was just thinking that I can hash a password
and use a keyring to store it to avoid the need for a database.
 
Question 2 :
 
 Can I split a private(decrypting) key and rejoin it using GPG ?
The split keys are given by two different people and rejoined.
 
I want to use the bouncy castle GPG API.
 
Thanks,
Mohan

Not within GPG.  GPG stores keys within keyrings.  Passphrases are  
stored outside the system (but see the gpg-agent for a local  
passphrase cache).

Not using GPG, but there are several tools available for split keys on  
the net.  For example: http://point-at-infinity.org//

That is not GPG.  That is a completely different implementation of the  
OpenPGP standard.  You should ask on the Bouncy Castle forums.
