Percentage of IRC SSL/TLS servers with key exchange Elliptic Curve Diffie-Hellman (ECDH) using X25519.Showing percentages for Ergo servers only.
About this test result: Elliptic Curve Diffie-Hellman (ECDH) using X25519 curve.
This ECDH with classic cryptography is widely used today. However, it is not a PQC algorithm, so is vulnerable to Harvest now, decrypt later.
