You are using invalid arguments in the functions (your compiler is probably giving various warnings about invalid types) and the second fopen call is clearly wrong. PEM_read_RSAPrivateKey returns RSA * so you need to do: privKey = PEM_read_RSAPrivateKey(file, NULL, NULL, NULL, NULL); similarly you should do: PEM_write_RSA_PUBKEY(file, privKey); Steve. -- Dr Stephen N.
