Re: Liberating Schneier's Code?
Yes, books are hard to update, but hardware is even harder. What is going to happen to all of those Capstone chips that use the "old" unfixed version of MD-5? Imagine what would happen if the Capstone was widely used in the country? It could easily cost many millions to update an algorithm in hardware.

Capstone chips do not use MD5. The algorithm in question was the gubmint's Secure Hash Algorythm, which is not the same as MD5. I don't think capstone uses SHA anyway...

Yes, Capstone uses SHA. I append a chunk from the most recent NIST Capstone release. Do we start calling it SHA-1? Will Capstone chips with SHA-2 interoperate with the ones already burned? Hmm.

In addition, the CAPSTONE chip includes the following functions: 1. The Digital Signature Algorithm (DSA) proposed by NIST as a Federal Information Processing Standard (FIPS); 2. The Secure Hashing Algorithm (SHA) recently approved as FIPS 180; 3. A Key Exchange Algorithm based on a public key exchange; 4. A general purpose exponentiation algorithm; 5. A general purpose, random number generator which uses a pure noise source. _______________________________________________________________________
