Work Description: jvz commented on pull request #176:
URL: https://github.com/apache/mina-sshd/pull/176#issuecomment-841696961
Let me clarify the IP provenance then. I have two versions of ChaCha20 and
Poly1305 in my O(1) Cryptography library. There's a Java port that I wrote
based on DJB's papers about ChaCha and Salsa (which are themselves public
domain and patent free) and the corresponding RFC that standardized it. There's
also a C version that is copied from one of the linked implementations from
https://cr.yp.to/chacha.html which is independent (and added much later). O1C
is my library where I'm the only copyright holder other than some C code that's
imported from elsewhere (the Java code is all pure Java, all done by
reimplementing or porting public domain algorithms from other languages).
Suffice to say, I've done due diligence in the library, and I can trivially
relicense any parts right now since nobody else has contributed yet.
