Is there any particular advantage or disadvantage of using symmetrical
rather than the extra RSA pair, or is this simply the way things are
Or is symmetrical less expensive computationally?
And whyle I'm asking such things, is one of the ciphers on livecode's list
If you use a heck-a-long key for the symmetrical stuff, it will be secure

I've been assuming 4k bits for payloads of a few hundred bites.
