Abstract
A method and system. A computer iteratively processes a unique condition digest of at least two condition digests in each iteration of a loop for a sufficient number of iterations to process all condition digests of the at least two condition digests. The processing in each iteration includes concatenating a reference digest with the unique condition digest of the iteration to generate a concatenand and hashing the concatenand to generate a hashed concatenand that serves as the reference digest for the next iteration if the next iteration is performed. Each unique condition digest is a different condition digest in each iteration of the loop. The regenerated reference digest of the last iteration of the loop is a last digest.
