Hi, I am trying to use a certificate with its public key algorithm is NIST P-384 and its signature algorithm is ED448. I am working on ESP board with IDF framework which supports mbedtls. But when I am trying to use that certificate, I got error message about 'MBEDTLS_ERR_X509_UNKOWN_SIG_ALG'. So, I thought that maybe mbedtls does not support certificates which signed with ED448.
Hello,
No, Mbed TLS does not support EdDSA (Ed25519, Ed448) yet. Given our current workload, we're unlikely to add support until mid- to late 2024. Please watch our roadmap https://mbed-tls.readthedocs.io/en/latest/project/roadmap/ for updates.
Best regards,
