Testing Elliptic Curve Cryptography – does your client support it?

Elliptic Curve Cryptography is the new black in the world of TLS. For the elite that works with crypto on a daily basis. it’s already pretty old, but for normal system administrators and developers is a new thing. We’ve added a new CA and three new tests for this cool technology! The race for bigger […]
