WebOct 21, 2024 · A general solution to the problem is to limit the CPU cycles spent by the server on connections from the same originating client. However such a solution is not always available. In that case the only other option is to limit the supported Diffie-Hellman groups so the amount of CPU cycles spent on a single TLS handshake is limited. WebConvert Ed25519 signing key pair into Curve25519 key pair suitable for Diffie-Hellman key exchange. This means that by exchanging only 32-byte Ed25519 public keys users can both sign and encrypt with NaCl. Note that there's currently no proof that this is safe to do. It is safer to share both Ed25519 and Curve25519 public keys (their ...
