Is it possible that pEvpkey or rsa is NULL? (You need to create a EVP_PKEY with EVP_PKEY_new() before putting a specific key into it.) Otherwise, have you checked whether there is anything in the openssl error stack (using ERR_get_error(), ERR_print_errors_fp(), or similar)? > I did google searching, but have not figured out why the about functions > failed (one posting mentions “export version” vs. domestic version??). There used to be different versions because of US export laws but I don't think that has been the case for many years. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
