Most people use cryptography every day. They log into websites. They check their bank balances. They send messages. They order things they absolutely do not need from online retailers at 2:00 AM.
Read article: RSA: The Internet’s Favorite Math Trick (Until Quantum Computers Show Up)Disclaimer: I’m not a physicist. This is my attempt to understand quantum computing and the underlying physics, yet keeping it light. I do actually want my traditional audience to read this.
Read article: Introduction To Quantum Computing: Because Regular Computers Apparently Weren’t Complicated EnoughThis is my second article about Zero-Knowledge Proofs (ZKPs). If you haven’t read it, check out Part 1 as a starting point.
Read article: Zero-Knowledge Proofs: The MathModern computing systems are built around a strange tradeoff in that proving identity or trust usually requires revealing information. Passwords, account numbers, private keys, medical records, financial history — all of these are routinely exposed simply to verify a claim.
Read article: Zero-Knowledge Proofs: Proving Something Without Revealing AnythingThe following blog posts are part of a series I wrote on digital signatures.

Read article: DSig Part 1: XML Digital Signature and WS-Security IntegrityThis tutorial describes how to convert a Binary Security Token extracted from a SOAP message into a valid PEM format that can be read by openssl or similar tool. If you are ever troubleshooting the use of X509v3 certificates used with WS-Security, this can come in very handy.
Read article: Convert an X509v3 Binary Security Token to PEM FormatThis post continues exploring the use of XML Digital Signature; this time we look at WS-Security Integrity (use of XML Digital Signatures with WS-Security). Our examples show a digital signature and a timestamp in a WS-Security <Security> SOAP Header.
