I want to add build-in function, it depend rust crates, such gluesql、csv, but
the https://github.com/mesalock-linux doesn't include these crates. How to fit
these rust crates to SGX?

I lauch the dacp reference implement teaclave_dcap_ref_as:
# ./teaclave_dcap_ref_as
Configured for development.
=> address: 0.0.0.0

=> tls: enabled
I use a wasm Excutor, the wasm file is 1.2M. I register the wasm function to
the teaclave. Some error have occured:
**_{'result': 'err', 'request_error': 'storage error'}
function_id = client.register_function(

executor(https://github.com/apache/incubator-teaclave/blob/master/docs/executing-wasm.md)
support python?

The teaclave_dcap_ref_as is builded on the steps:
**docker run --rm -v $(pwd):/teaclave -w /teaclave \
-it
I use the dcap client 'teaclave_sgx_tool ' to get attentation with the dcap
service, but some error was occured.
The commend is:
_./teaclave_sgx_tool attestation --url https://localhost:8080 --algorithm
sgx_ecdsa_
The error is：
_root@cc:~/incubator-teaclave# Configured for development.
> For DCAP, `AS_ALGO` is `ecdsa`. `AS_URL` is the URL of your data center
> attestation service. `AS_KEY` and `AS_SPID` are not used for DCAP.
How to get the 'dcap_root_ca_cert.pem'？ And do there have any complete material
introduce how to install DCAP and use it？

请问一下：
1、按照这个项目https://github.com/intel/SGXDataCenterAttestationPrimitives，安装好dcap之后，如何使用这个安装好的dcap认证服务呢？
2、使用dcap认证服务，mesatee是不是需要重新编译？需要修改哪些配置呢？
谢谢

请问一下，mesatee是怎么进行sgx的合法性验证的？
$ export AS_SPID="" # SPID from IAS

$ export AS_KEY="" # Primary key/Secondary

$ export AS_ALGO="sgx_epid" # Attestation algorithm,

比如求交、表join、表过滤之类的数据库操作

请问下：
incubator-teaclave-master\tests\fixtures\functions\private_join_and_compute\three_party_data\*.enc下面的加密文件如何获得的，加密文件在tee里面是怎么解密的？tee传输回来的数据文件如何解密？整个mesatee的加解密机制是如何的，有相关资料吗？

(cd docker && docker-compose -f docker-compose-ubuntu-1804-sgx-sim-mode.yml up
--build)
docker-compose启动的
builtin_face_detection.py
builtin_online_decrypt.py这些都能运行成功。看了以下差异好像是builtin_face_detection.py
使用模拟模式运行gbdt示例，出现报错
运行命令：$SGX_MODE=SW PYTHONPATH=../../sdk/python python3 builtin_gbdt_train.py
出现错误：
'result': {'result': {'Err': {'reason': 'ocall error = 1'
这是什么问题呢？
