[GitHub] [incubator-teaclave] czzmmc opened a new issue #305: Got error when invoking echo function by python!
czzmmc opened a new issue #305:
URL: https://github.com/apache/incubator-teaclave/issues/305
Hi, I use simulation mode and I successfully run the 7 services. When I executed python code builtin_echo.py, I got a openssl error message like below.
Traceback (most recent call last):
File "builtin_echo.py", line 199, in <module>
main()
File "builtin_echo.py", line 191, in main
rt = example.echo(message)
File "builtin_echo.py", line 158, in echo
verify_report(AS_ROOT_CA_CERT_PATH, ENCLAVE_INFO_PATH, cert, "authentication")
File "incubator-teaclave/sdk/python/teaclave.py", line 41, in verify_report
signing_cert = load_certificate(FILETYPE_ASN1, signing_cert)
File ".local/lib/python3.6/site-packages/OpenSSL/crypto.py", line 1794, in load_certificate
_raise_current_error()
File ".local/lib/python3.6/site-packages/OpenSSL/_util.py", line 54, in exception_from_error_queue
raise exception_type(errors)
OpenSSL.crypto.Error: [('asn1 encoding routines', 'ASN1_get_object', 'header too long')]
I know I am using demo certs. Do I need to generate those files by myself? Is it related to my openssl lib version or something like that?

If you are using simulation mode, there is no attestation. Please set the env var `SGX_MODE` before starting the example by `export SGX_MODE=SW`.
See: https://github.com/apache/incubator-teaclave/blob/master/sdk/python/teaclave.py#L202
I'll update the doc later.
