Verifying TPM Endorsement Certificates with wolfTPM

We’re excited to share a new feature added to wolfTPM: a lightweight example for verifying TPM Endorsement Key (EK) Certificates without wolfCrypt. The new example, `verify_ek_cert`, retrieves and verifies the EK certificate stored in the TPM’s non-volatile memory. This supports TPMs like the Infineon SLB9672/SLB9673, STMicro ST33 series, and validates their RSA-signed EK certs using […]

ML-KEM Versus HQC KEM

ML-KEM (Module-Lattice Key Encapsulation Mechanism) and HQC (Hamming Quasi-Cyclic) are both post-quantum cryptographic key encapsulation mechanisms (KEMs) designed to provide secure key exchange in the presence of CRQCs (Cryptographically Relevant Quantum Computers). ML-KEM is based on the (M-LWE) Module Learning With Errors problem, which involves finding a short vector between two points in a high […]

ML-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 […]

Using 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 […]
