  The IEEE P1363 project has as its goal the issuance of Standard Specifications For Public-Key Cryptography. The main standard document specifies algorithms in 3 families of cryptographic functions: discrete logarithm in the group of remainders modulo a prime (DL), discrete logarithm in the group of points on an elliptic curve over a finite field (EC), integer factorization (IF). The documentation has a number of annexes, describing: mathematical and cryptographic background, number-theoretic algorithms, reasons and security considerations, bibliography.

• Cryptlib Security Software Development Toolkit
  Cryptlib is a powerful security toolkit which allows even inexperienced crypto programmers to easily add encryption and authentication services to their software.
  By Peter Gutmann, New Zealand. Alternate site: cryptlib.orion.co.nz.
  Included are implementations of the most popular encryption and authentication algorithms: AES, Blowfish, CAST, DES, Triple DES, IDEA, RC2/4/5, Safer, and Skipjack conventional encryption; MD2/4/5, RIPEMD-160 and SHA hash algorithms; HMAC with MD5/SHA/RIPEMD-160, and MDC-2 MAC algorithms; and Diffie-Hellman, DSA, Elgamal, and RSA public-key encryption. Cryptlib has full X.509 certificate handling, with additional support for SET, Microsoft AuthentiCode, Identrus, S/MIME, SSL and PKCS #7 certificates. Cryptlib can also make use of the crypto capabilities of external crypto devices such as hardware security modules (HSMs), Fortezza cards, PKCS #11 devices, and smart cards.
  Cryptlib is supplied as source code for Unix (static and shared libraries), DOS, Windows 3.x, Windows 95/98/ME, Windows NT/2000/XP, OS/2, BeOS, Macintosh, and the Tandem environment; and also as 16- and 32-bit Windows DLL's. cryptlib is also available as an ActiveX control for Windows, and adaptations exist for VM/CMS and MVS mainframe environments.
  Cryptlib can be used without charge for evaluation, freeware and shareware applications and for research purposes and non-revenue-generating personal uses. All commercial use of Cryptlib (revenue-generating purpose in a company or in an application product) requires a commercial software license of Cryptlib.

Prime Numbers

• PRIMES is in P
  Prof. Manindra Agarwal and two of his students, Nitin Saxena and Neeraj Kayal (CSE/IITK, India), have discovered a polynomial time deterministic algorithm to test if an input number is prime or not. Lots of people over (literally!) centuries have been looking for a polynomial time test for primality, and this result is a major breakthrough, likened by some to the P-time solution to Linear Programming announced in the 70s.
  One of the main features of this result is that the proof is concise, clever and elegant, and relies on very innovative and insightful use of results from number theory.
