Well, this true when I use gpg in both ends.
But my problem is that the opposite end only uses symmetric ciphers and
I have to inform them about my 3DES key for this session (encrypted with
another 3DES key).
So therefore I need to generate 3DES keys, encrypt it with a given 3DES
key, at send it to the receiver.
(I haven't 'invented' this system, the receiver did.)
So is there any way I can generate/get 3DES key?
Perhaps using some library?
