- Hi, I've been looking at implementing RSA encrpytion and have found that
- generating the initial keys is a somewhat tricky. The only algorithm
- I have found for generation the public key is:
-
- N = x*y
- p*s mod (x-1)(y-1) = 1
-
- and solve for p. :(
-
- Is there an easy way to solve this problem ?
-
- If anyone can give me some clues on how to do this, it would be great
- (or even where to look for some clues :).

- Hans Riesel, _Prime Numbers and Computer Methods of Factorization_,
- 1985. (Or something like that -- my copy is at home so I may have got
- the title slightly wrong.)
-
- Both of these have good introductions to RSA and RSA-like encryption
- methods. Both should be available in a good university library; Knuth
- at least is still in print and I'd argue strongly that every
- programmer should own a copy of all three of his volumes.
