Sorry. My mistake. I actually meant what does EVP_PKEY_id() return.
That just does this:
int EVP_PKEY_id(const EVP_PKEY *pkey)
{
return pkey->type;
}
So if you get EVP_PKEY_RSA_PSS returned from that I don't currently
understand how this:
RSA *EVP_PKEY_get0_RSA(const EVP_PKEY *pkey)
{
if (pkey->type != EVP_PKEY_RSA && pkey->type != EVP_PKEY_RSA_PSS) {
EVPerr(EVP_F_EVP_PKEY_GET0_RSA, EVP_R_EXPECTING_AN_RSA_KEY);
return NULL;
}
return pkey->pkey.rsa;
}
Can return the error you saw!! Something strange going on...
