• In private correspondence with Chris K. Caldwell on 10 Aug 2003, I announced that ^C5 = 2^(2127-1)-1 has no prime factor < 10⁵¹.
• The algorithm used by the Amdahl 6 is available as part of the calc distribution.

Misc mathematics

Crypto papers

• ``Partial Key Escrow,'' Adi Shamir and Landon Curt Noll; a web page proposal for a more civil liberty friendly key escrow system.

Crypto software / Demos

• LavaRnd - Seeding a pseudo-random number generator with the cryptographic hash of a digitization of a chaotic system
• ``NLC''. The Noll Lighting Cypher that turns SHA-1 (one way hash used by the Digital Standard) into a block cypher.
• ``sha(1), sha1(1) and md5(1)'', optimized cryptographic hash tools with multi-phase, prefix, inode and other enhancements by Landon Curt Noll. A source tarball as well as a directory are available. This code made it into BSDI's BSD/OS source distribution.
