md5 is not patented. des and 3des the patent expired. Blowfish was originally published not patented. That's all I know. With Cisco IPSec work just about all configs use md5, sha, des and 3des and Cisco isn't known for liking to pay royalties to anyone.

Hello,







Thanks,

We are using OpenSSL in an embedded device. I have been told that some of the cipher suites include patented algorithms that must be licensed. The OpenSSL FAQ is intentionally vague about what algorithms are protected, although it recommends a specific configuration to remove RC5, IDEA and MDC2. Are these the only three that are protected? Is there anywhere I can find out definitively what algorithms are protected?
