Hello embhorn,

I am using version 5.8.4. I want to make a TLS Handshake, while using ThreadX and NetXDuo.
Using X25519/ED25519 works fine so far, but I will take a look at this example for the PQC. Thx.

Cheers,
Michael

Hello Mika,

Which version of wolfSSL are you building? Here is an example config used to run the PQC benchmarks on an STM32F439ZI
https://github.com/wolfSSL/wolfssl/blob … tm32f439zi

Could you tell us a bit about your project using wolfSSL?

Kind regards,
Eric - wolfSSL Support

./Middlewares/wolfssl/src/internal.c:29243:16: error: 'WOLFSSL' has no member named 'pkCurveOID'
29243 | ssl->pkCurveOID == CTC_ML_DSA_LEVEL5

for example I get this error, when WOLFSSL_WC_DILITHIUM enabled.

Hello there,

I am struggling to set up the correct defines to activate this algorithms for TLS:

#define WOLFSSL_HAVE_KYBER
//#define HAVE_DILITHIUM
//#define WOLFSSL_DILITHIUM_SMALL
#define HAVE_DILITHIUM_LEVEL5
//#define WOLFSSL_PQC_ONLY
#define NO_ECC
//#define WOLFSSL_MLKEM
//#define WOLFSSL_MLKEM_KYBER
#define WOLFSSL_WC_DILITHIUM
#define WOLFSSL_SHAKE256
#define WOLFSSL_SHAKE128
#define WOLFSSL_SHA3
#define WOLFSSL_WC_MLKEM
//#define HAVE_LIBOQS
//#define WOLFSSL_EXPERIMENTAL_SETTINGS

I get quite many errors, because something is missing.
