MpNT is a multi-precision number theory library that provides a base for building cryptographic applications. It may also be used in any other domain where efficient large number computations are required. The library supports integer, modular, and floating point arithmetic with practically unlimited precision. It is both speed efficient and highly portable without disregarding code structure and clarity.

GPGlist is a Perl script to implement gpg encrypted alias lists in a mail server such as Sendmail or Postfix. It uses one XML config file to store information about lists. It backs up messages if an error occours, and sends out error messages to the sender of the mail. You can decide whether or not a list only accepts encrypted messages.

OpenSignature is a project for the digital signature of documents. It works with all cards supported by OpenSC, and focuses on adding support for cards from accredited Italian CAs. The goal is to provide the first single product capable of supporting cards from multiple vendors/countries. This contrasts the approach taken by card vendors/providers whose software follows an exclusive single-vendor approach. OpenSignature attempts to make a major contribution to interoperability in the digital signature domain, and aims to greatly facilitate the setup of public access points that are currently the objective of several projects in Italy.

Vit 54.91

FastFlex is a cryptographic function, which uses a new approach to construct a secure cryptographic function which performs quite fast on processors of varying word length and architectures. FastFlex uses only four basic operations, word additions, word XORs, word rotations, and word multiplications, found in instruction sets of almost all processor architectures. FastFlex also has a manageable internal state size of 256 bits. A single 1KB s-box is used. The function accepts 8 words as inputs and as output produces 8 words.
