> | ### D.12.3 crypto_lib Library: crypto.lib Purpose: Procedures for teaching cryptography Author: Gerhard Pfister, pfister@mathematik.uni-kl.de Overview: The library contains procedures to compute the discrete logarithm, primality-tests, factorization included elliptic curves. The library is intended to be used for teaching purposes but not for serious computations. Sufficiently high printlevel allows to control each step, thus illustrating the algorithms at work. Procedures:
