Find correct key id's

[Mohan Radhakrishnan]

Hi,
       I think as a newbie I was confused because --list-packets and BC
API printed two different ID's. Correct me if I am wrong.


It looks like when I use a user id like this and encrypt

gpg --output readme.gpg --recipient test123 at test.co.in --encrypt
CHANGE.txt     

the output from "--list-packets readme.gpg" is 2048-bit RSA key, ID
6540BD43, created 2010-02-11 (main key ID 202AAEDC)


but when I use code like this to get a key for encrption

            while ( rings.hasNext()) {

            	PGPPublicKeyRing ring = (PGPPublicKeyRing) rings.next();

               	key = ring.getPublicKey();

    				if( null == key ){
    					throw new
KeyNotFoundException();
    				}

    	        	for( Iterator userIds = key.getUserIDs() ;
userIds.hasNext() ; ){

    	    			userId = ( String )userIds.next();

    	        	}
	    			//Read from properties file
	    			if( userId.equals( "test123 at test.co.in"
)){
	        			break;
	        		}
            }

The output from --list-packets is 2048-bit RSA key, ID 202AAEDC, created
2010-02-11

So it looks like in the first instance it shows the sub-key but in the
second case it seems to be showing the main key.

Thanks,
Mohan

Is "--try-all-secrets" not helping you?
