TLS Key exchange group: P-384

Percentage of IRC SSL/TLS servers with key exchange Elliptic Curve Diffie-Hellman (ECDH) using P-384 (secp384r1).
Showing percentages for Solanum servers only.

About this test result: Elliptic Curve Diffie-Hellman (ECDH) using P-384 curve (also called secp384r1).
This ECDH with classic cryptography is widely used today. However, it is not a PQC algorithm, so is vulnerable to Harvest now, decrypt later.
