Your new key will be generated from prime numbers produced by a random number generator. In order for your key to be unpredictable we need to collect a large amount of random data from the only source in the system which is unique : you. This data will be used to seed the random number generator. To ensure maximum security, the SecEx Key Generator does not avail itself of previously calculated prime numbers or so called "canned primes." All prime numbers are generated "on the spot".
