I was juz discussing with my pals the other day on the appropriate initial
input bit size to seed a PRNG of the structure below for it to be used to
generate the random bits for RSA key material of modulus 1024 bits or 2048
bits. Anyone know what would be the ideal length/size of A so that there
is sufficient entropy to generate the key material for RSA 1024/2048 bits
keys?
that'll depend on how you use the output of the PRNG to generate an RSA key.
As a general rule I'd say A should have one bit of entropy for every bit
of O that you use. You didn't tell us anything about how A is constructed,
so we can't say how long it should be.
Bye,
