I believe the culprit is here.
I am wondering whether somebody else had a similar issue.

terminal output

I’m seeing the same thing @nioni. I can’t figure it out :-P. I see how you’re trying to use the enigma-crypto interface in your demonstration code. Pretty cool. I’ll follow-up with the team tomorrow to see if we can resolve this!

@nioni I was able to resolve the build error by making a modification to the enigma-crypto dependency in your Cargo.toml file. I used the example Enigma encryption secret contract as a reference to try to fix your build error: https://github.com/enigmampc/enigma-core/tree/develop/examples/eng_wasm_contracts/encryption

enigma-crypto = { git = "https://github.com/enigmampc/enigma-core.git", default-features = false, features = ["asymmetric", "hash"] }

And in your lib.rs I used eng_wasm::generate_key() instead of KeyPair::new() to generate the random encryption key. Then used KeyPair::from_slice(...) to create the KeyPair.

The modified demonstration secret contract looks like this:

pub struct Contract;
impl ContractInterface for Contract {
  fn construct() -> () {
    write_state!(STATE => State {
      private_key: generate_key(),
      nonce: U256::from(0)
    });
  }

  fn get_public_key() -> String {
    let private_key = Self::get_state().private_key;
    let key_pair = KeyPair::from_slice(&private_key).unwrap();
    let public_key = key_pair.get_pubkey();

    return public_key.to_hex::<String>();
  }

  fn get_nonce() -> U256 {
    return Self::get_state().nonce;
  }
}

I wasn’t able to get it to build using KeyPair::new() like you had because that’s only available for SGX environments.

Thank you for helping out again!, my bad for not following the example.
I got a little bit confused because on the docs.rs for eng_wasm I couldn’t find generate_key, and I thought it was something still in development.

No problem! Glad to help :smiley:

hi @nioni the docs maybe built failed but i can find the source here

hi @ainsley the eng_wasm ver 0.1.4 built failed already. Can you guys take a look?

Just checking in on this-- is this issue still open, or were you able to resolve @nioni ?

Yes! thank you @laura :slight_smile:

I’ve had to make some small changes to cargo.toml.

Versions have to be exactly 0.1.4 hence the = 0.1.4 or else generate_key() is not available.
