If your modus operandi includes exchanging secret information outside of normal channels (e.g., "change the case of the nth letter") you would be better off exchanging more secure information than a single change like that. For example - a second set of public keys. Encyrpt your document twice, first with your friend's "private" public key, then with his public-public key. Or exchange the passphrase to a symetrically encrypted file, then encypt the symmetrically encrypted file with his public key.
Hell, try one-time pads. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
