I don't use PGP at the moment, but isn't it one of the points? I mean, you have to exchange public keys (or download them from the keyservers) in order to be able to decrypt and check the signature. Also, if somebody pastes their key into a message body and then clearsigns the message, TB! will not import the key to your keyring if the key is not already there to check the signature? I believe you need to issue a command to tell TB! to import the key. M Can anybody duplicate this? M Alternatively, does anybody observe different behaviour? I cannot test it, but what you describe is what I would expect. -- Cheers, Thomas. http://thomas.fernandez.hat-gar-keine-homepage.de/ Message reply created with The Bat! 4.2.10.6 under Windows XP 5.1 Build 2600 Service Pack 3 Current version is 4.2.10.0 | 'Using TBUDL' information: http://www.silverstones.com/thebat/TBUDLInfo.html

The behaviour I am questioning seems peculiar to The Bat!. It is usually possible with PGP (or GPG) to decrypt a message that is encrypted to your key, whether or not it happens to also be signed and whether or not you have a key to check the signature. TB! will not do this. You need your secret key to sign a message. Anybody needs your public key to check a signature that you made with your secret key. You need somebody's public key to encrypt to them. You need your secret key to decrypt a message that somebody has encrypted to your public key. You do not need their key to decrypt the message. -- Best regards MFPA Reality is nothing but a collective hunch.

PGP encrypted and signed message cannot be decrypted in TB! if you don't have sender's public key to check signature
Hi Can anybody confirm that a PGP encrypted and signed message cannot be decrypted in TB! if you don't have the sender's public key to check the signature? Also, if somebody pastes their key into a message body and then clearsigns the message, TB! will not import the key to your keyring if the key is not already there to check the signature? -- Best regards MFPA I'll tell you what's the matter!
