I guess this means that this function will be in later versions of OpenSSL
:-)

Well... actually there is no RSA_dup() either :-)...... but the following
should works as well:
....
EVP_PKEY* pDupKey = EVP_PKEY_new();
RSA* pRSA = EVP_PKEY_get1_RSA(pKey);
EVP_PKEY_set1_RSA(pDupKey, pRSA);
RSA_free(pRSA);
return(pDupKey);
Thanks!
