ABSTRACT:
A method of compressing a cryptographic value. The method comprising the steps of: (a) selecting a secret value; (b) performing a cryptographic operation on the secret value to generate the cryptographic value; (c) determining whether the cryptographic value satisfies the pre-determined criteria; and (d) repeating the sequence of steps starting at step (a) until the cryptographic value satisfies the pre-determined criteria.
