PROVABLEPRIME Version 1.1.2, Generation of provable primes with Maurer's algorithm, with illustrative coding of RSA encryption (with authentication) and digital signature for sequences of fixed-sized plaintext blocks and RSA pseudo-random bit generation, has been released:
http://s13.zetaboards.com/Crypto/topic/7234475/1/ It is presumably the final polished-up version of PROVABLEPRIME. There is to my knowledge currently no other open-source implementation of Maurer's algorithm in any other popular programming language. The demonstration, that digital signatures can be done with RSA alone, i.e. without additionally employing hashing, appears also to be unique. M. K.
