ecdhtest: fix a couple bugs plus some cosmetic tweaks

Rework the ecdhtest

2023-07-15T23:35:02+00:00

Test keyshare for all built-in curves and simplify, especially printing on failure. Incorporate known answer tests from RFC 5114 and RFC 5903. All in all, this is a lot less code and a lot more test coverage and hopefully a little less eyebleed. Very loosely based on OpenSSL b438f0ed by Billy Brumley

Fix return value check for ECDH_compute_key()

2023-07-15T20:11:37+00:00

ECDH_compute_key() usually returns -1 on error (but sometimes 0). This was also the case in OpenSSL when these tests were written. This will soon change. The check for <= 0 will still be correct.

Add test coverage for cofactor ECDH using NIST test vectors

2023-07-15T19:51:13+00:00

Since all non-binary NIST curves have cofactor 1, this is in effect plain ECDH. Current regress coverage of ECDH is quite lacking on architectures where Go isn't available. This fixes that. Actual cofactor ECDH support may be added soon to libcrypto, at which point I will also add testcases with cofactor > 1.
