Read MoreMore TagML-KEM Versus ML-DSA
ML-KEM (Module Lattice Key Encapsulation Mechanism) is for secure key exchange. ML-KEM enables two parties to establish a shared secret key over an insecure channel. ML-DSA (Module Lattice Digital Signature Algorithm) is for authentication. ML-DSA allows a signer to generate a digital signature that can be verified by others, ensuring the authenticity and integrity of […]
Read MoreMore TagUsing ECH with curl and wolfSSL
The Server Name Indication (SNI) extension to TLS allows the client to specify the name of the server it is trying to connect to, which allows the server to select between multiple virtual servers and present the appropriate certificate for the connection. The client sends the server name as a part of a Client Hello […]
