(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
