Hi,
I am not getting different functions in OpenSSL 3.0 for accessing
different fields of typedef struct evp_pkey_st EVP_PKEY. For Example -
code is like this -
EVP_PKEY * privKey;

if ( BN_cmp(privKey->pkey.rsa->n, pubKey->pkey.rsa->n) != 0 )
BIGNUM *privn = NULL, *pubn = NULL;
/* Error handling omitted for brevity...*/
EVP_PKEY_get_bn_param(privKey, "n", &privn);
EVP_PKEY_get_bn_param(pubKey, "n", &pubKey);
if ( BN_cmp(privn, pubn) != 0)
...
BN_free(privn);
BN_free(pubn);

else if ((privKey->type == EVP_PKEY_EC) && (pubKey->type == EVP_PKEY_EC))
else if (EVP_PKEY_is_a(privKey, "EC") && (EVP_PKEY_is_a(pubKey, "EC"))
