This page features tools and documentation centered around crypto-software. Unless otherwise noted, this is brought to you by OpenFortress digital signatures under a friendly BSD style license.

The most recently added features on OpenFortress sites:

  • Linux-PAM authentication with crypto-hardware -- The CrypToken page now features an authentication solution based on ePass1000 USB-tokens and Linux-PAM. It is based on a novel cryptographic trick that gets the most out of this kind of symmetric token.
  • Bitdiff counts bitflips in hash outcomes -- Secure hashes such as MD5 and SHA1 claim to flip half their bits on any change to the input, because every input bit is influence on every output bit. This simple tool counts the bits that differ between two hashing outputs in hexadecimal.
  • Dutch: OpenFortress trekt Sinterklaaslootjes als demonstratie van hoe simpel en elegant de inmenging van een buitenstaander kan zijn; want die buitenstaande heeft geen interesse in de zaak en kan dus vertrouwd worden om haar taak netjes te vervullen. (added Nov 19)
  • Securing DNS with DNSsec. This Dutch article explains how DNSsec can be used to avoid DNS spoofing, and inhowfar that solves security problems.
  • OpenBSD: extreem in security. This Dutch article compares OpenBSD to Linux from a security viewpoint.
  • Identity checks that leave privacy intact. This demonstration shows that privacy laws need not be loosened to serve all sorts of `black list' or `white list' checks.
