- I hope this is not a FAQ, but if so, please direct me accordingly, thanks.

- Would multiple encryptions add to the level of security of, say, a PK system
- like RSA or a knapsack scheme? What I mean is to encrypt the clear text and
- then encrypt the encrypted text, probably with a different key. If encryption
- of binary poses a problem, one could, say, uuencode the encrypted text. This
- could, in theory, provide an arbitrary number of successive encryptions which
- would, as far as I can see (which ain't saying much anymore :)) effectively
- offer the equivalent of encryption with very large keys (say, >10000 digits).
-
- Would this work? Would there be any difficulty in decryption? It seems to
- me you could mutate the clear text with basically no limit, beyond, perhaps
- eventually winding up with the clear text again. Anyone have any thoughts on
- this?
