Re: PRNG State [was: KeyTool internal state]

I wonder if you are confusing the length in bits of a PKC key, e.g. a prime factor of an RSA public key, with the entropy of that private key. The prime factor may be 512 bits long, but it usually does not have anyway near 512 bits of randomness. Usually a secret prime is generated by adding a

PRNG State [was: KeyTool internal state]

2000-04-02 Thread Andrew Cooke
Hi, Can someone please correct the following? I expect a PRNG with an internal state of n bits to produce output that is predictable given n consecutive bits of output. Is that correct? If so, then doesn't a PRNG used to generate a key require at least as large an internal state as the key le
