Hello,

First sorry for opening an Issue, but I did not know where to put the following (no discussion enabled?). I am opening this mostly for tracking, and to maybe help other people find this code in the future.

Long story short: I have been trying to run integritee-cli on mobile(ie an Android app), and it seems to be working! [NOTE: WIP, not prod-ready!].
The results are there.

It was not too much work:

• refactor integritee-cli to return Result everywhere
  • move most Cli code from main.rs to lib.rs
  • add pub enum CliResultOk and pub enum CliError
  • most changes are in perform_trusted_operation/send_request/etc to expose an Error instead returning None

Then on the Android project:

• a [patch."https://github.com/apache/teaclave-sgx-sdk.git"] sgx_crypto_helper
  Which replaces sgx_tcrypto/sgx_ucrypto by an impl that uses rsa+sha2+rand cf the fork[NOTE: REALLY WIP]
• a [patch.crates-io] wasmtime and one-liner fix cf this fork[NOTE: REALLY WIP too]

Note that both of those are definitely PoC-level; as in "make sure it can run an Android" and I will see later to clean it up.

If you are interested, I could find some time to clean up the code and make a proper PR?
Maybe at least for integritee-cli at first?
