TLS Key exchange group: P-256
Percentage of IRC SSL/TLS servers with key exchange Elliptic Curve Diffie-Hellman (ECDH) using P-256 (prime256v1, secp256r1).Showing percentages for ngircd servers only.
About this test result: Elliptic Curve Diffie-Hellman (ECDH) using P-256 curve (also called: prime256v1, secp256r1).
This ECDH with classic cryptography is widely used today. However, it is not a PQC algorithm, so is vulnerable to Harvest now, decrypt later.
