Hello to all,
Below are the setup details I'm using:
- nRF52840 DevKit
- SDK: nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b
- Segger Embedded Studio 4.16
I am working on a project that requires srp to be implemented. I am using the attached code that uses mbed tls library. I am getting following error in the function mbedtls_ecdsa_genkey(). I am not able to debug the same.
// Function to generate a key
int
generate_key(srp_key_t * key)
{
int status;
char errbuf[64];
if (srp_key_setup(key) < 0)
{
return -1;
}
const mbedtls_pk_info_t *key_type = mbedtls_pk_info_from_type(MBEDTLS_PK_ECKEY);
if (key == NULL || key_type == NULL) {
return -1;
}
if ((status = mbedtls_pk_setup(&key->key, key_type)) != 0) {
mbedtls_strerror(status, errbuf, sizeof errbuf);
ERROR("mbedtls_pk_setup failed: %s", errbuf);
} else if ((status = mbedtls_ecdsa_genkey(mbedtls_pk_ec(key->key), MBEDTLS_ECP_DP_SECP256R1,
mbedtls_ctr_drbg_random, &key->ctr)) != 0) {
mbedtls_strerror(status, errbuf, sizeof errbuf);
ERROR("mbedtls_ecdsa_genkey failed: %s", errbuf);
} else {
return 0;
}
srp_keypair_free(key);
return -1;
}
mbedtls_ecdsa_genkey () returns with 1 and is stored in the the status, and also it prints the error string on debug terminal as mbedtls_ecdsa_genkey failed: without the actual error message, please find the attached picture of the error message
I would appreciate any pointers to what I might be missing.
Kind regards,
Shivaprasad
