Problems generating keys on OpenPGP SmartCard V2

2009-11-19 Thread Helmut
Hi there, I'm new to the list and actually trying to get my Smartcard working for encryption, using the Shell Token V2 from gemalto. If I try to generate a key or to change the password of the card, I get errors (see debug below). I bought a OpenPGP SmartCard V2 from kernel concepts and

There is no way (yet, ;-) ), to do what you want in gnupg, as a gnupg encrypted file will show that it was encrypted either symmetrically or to a key. But, if you don't mind XOR-ing with a large pad, and you have a secure place to keep the pad, (not on the computer with the encrypted files),

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 November 19th 2009 for gnupg-users@gnupg.org IMO steganography should be mixed with cryptography to be secure. As example: LSB in pictures (Unless you have a professional camera) will be random (High entropy and no predecible). You can replace it
