[openssl-users] [openssl-dev] Failed TLSv1.2 handshake with error 67702888--bad signature

[Nounou Dadoun]

That's a useful thing to try - given the earlier mismatch, I suspect that it may be something in the hash calculation that's not quite lining up and causing the signature match to fail.  thanks for the suggestion .. N

Given that your server is on ARM, which is not yet a widely used platform for OpenSSL 1.0.2, most
likely the issue is there.  So disabling ASM on the server side is worth a try.

Also test your client against non-ARM 1.0.2d servers...
