How Many IETF RFCs Actually Become Standards?
The Internet Engineering Task Force (IETF) has 10K+ published Request For Comments (RFCs) documents. The industry hears about RFCs all the time. But, as the name implies (“request for comments”) that isn’t the final step in the process. A very small number of RFCs are promoted to Internet…

Post-Quantum Cryptography (2026): Preparing for the End of RSA and ECC
For decades, modern cybersecurity has relied on a handful of cryptographic foundations. Technologies such as RSA and Elliptic Curve Cryptography (ECC) protect everything from online banking and VPNs to software updates and digital signatures. These algorithms have withstood years of scrutiny and…

WS-Security Integrity (XML Digital Signature)
This 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.

XML Digital Signature (an Example)
In the last post, we looked at the steps involved in generating a digital signature using the XML Digital Signature spec. The algorithm to produce a signature and validate it were explored but no examples were given. In this post, we’ll look at an example that is given in the XML Digital Signature…

XML Digital Signatures
The XML DSig specification is used to provide digital signature functionality to XML Documents. It is is used by numerous other specs such as WS-Security and SAML2. This blog entry will describe how digital signatures work with an X509 private/public key pair.
