Branch: MAIN
CVS Tags: HEAD

FILE REMOVED
Update/replace the experimental post-quantim hybrid key exchange method based on Streamlined NTRU Prime (coupled with X25519). The previous sntrup4591761x25519-sha512@tinyssh.org method is replaced with sntrup761x25519-sha512@openssh.com. Per the authors, sntrup4591761 was replaced almost two years ago by sntrup761. The sntrup761 implementaion, like sntrup4591761 before it, is public domain code extracted from the SUPERCOP cryptography benchmark suite (https://bench.cr.yp.to/supercop.html). Thanks for Daniel J Bernstein for guidance on algorithm selection. Patch from Tobias Heider; feedback & ok markus@ and myself (note this both the updated method and the one that it replaced are disabled by default)

switch sntrup implementation source from supercop to libpqcrypto; the latter is almost identical but doesn't rely on signed underflow to implement an optimised integer sort; from markus@

Branch: MAIN
Add support for a PQC KEX/KEM: sntrup4591761x25519-sha512@tinyssh.org using the Streamlined NTRU Prime 4591^761 implementation from SUPERCOP coupled with X25519 as a stop-loss. Not enabled by default. introduce KEM API; a simplified framework for DH-ish KEX methods. from markus@ feedback & ok djm@
