PEM_read_PrivateKey
call
PEM_read_bio_PrivateKey(BIO *bp, EVP_PKEY **x, pem_password_cb *cb, void
*u)
{
if (!PEM_bytes_read_bio(&data, &len, &nm, PEM_STRING_EVP_PKEY, bp, cb, u))
return NULL;
p = data;
if (strcmp(nm,PEM_STRING_RSA) == 0)
ret=d2i_PrivateKey(EVP_PKEY_RSA,x,&p,len);
else if (strcmp(nm,PEM_STRING_DSA) == 0)
ret=d2i_PrivateKey(EVP_PKEY_DSA,x,&p,len);
else if (strcmp(nm,PEM_STRING_ECPRIVATEKEY) == 0)
ret=d2i_PrivateKey(EVP_PKEY_EC,x,&p,len);
}
the cert nm find -----BEGIN EC PRIVATE KEY-----
then call
ret=d2i_PrivateKey(EVP_PKEY_EC,x,&p,len);
id d2i_PrivateKey()
#ifndef OPENSSL_NO_EC
case EVP_PKEY_EC:
if ((ret->pkey.ec = d2i_ECPrivateKey(NULL,
(const unsigned char **)pp, length)) == NULL)
{
//ASN1err(ASN1_F_D2I_PRIVATEKEY, ERR_R_ASN1_LIB);
goto err;
}
break;
#endif
so last it's call
d2i_ECPrivateKey
but my ec curve is not in openssl curve list so it's error to read private
key

Hi Girish,
Can u explain how d2i is indeed getting resolve to
d2i_RSAPrivateKey() ?

Sorry I was wrong. d2i indeed resolves to
d2i_RSAPrivateKey() which takes 3 parameters and
passes the first type parameter to d2i_PrivateKey()
which takes 4 parameters.
But it beats me why I cannot find the definition of
d2i_RSAPrivateKey() anywhere.
