Hello,
I compiled it using sun compiler, with some modifications to the source
code.
However :)
openssl s_client -connect google.com:443 -tls1_2
works fine !
But
openssl s_client -connect google.com:443 -tls1_3
fails on CRYPTO_memcmp.
For easy debugging, I have made a copy of CRYPTO_memcmp in gcm128,
called CRYPTO_gcm128_memcmp.
Here is what I get (added some log 😅). As you can see, ctx->Xi.c and tag
don't match.
I have looked for hours to find why, with no luck yet.
Any idea how to debug this ? Some tests to run to check if everything is ok
?
crypto/modes/gcm128.c:1931 ctx->EK0.u[0]=a2e1d0203e9a02ca
