teTLS

"teTLS" started as a project to provide attested HTTPS requests and responses. The "te" stands for "trusted execution [environment]", so "teTLS" is similar to "zkTLS" in that both seek to provide verifiable TLS communication. teTLS currently only provides attestations for HTTPS request and responses and not for generic TLS sessions.

In the spirit of experimentation, the current teTLS implemenation has outgrown its name. The service also can produce attested cryptographically strong random bytes. It can also attestably execute Javascript (as strange as that might sound). This Javascript implemenation is executed by a WASM engine, so it would be easy to execute arbitrary WASM, too. Javascript (and any WASM) has full access to HTTP requests as well as to those random bytes. The goal is a simple facility for doing pure computation as glue code around HTTP requests and random numbers.

The combination of attested HTTP requests, random bytes, and arbitrary Javascript execution (that make those HTTP requests and get those random bytes) is a very capable system for a wide range of tasks that require attestation.

Some documentation is available. See examples/examples.sh, with output at examples/examples-transcript.txt, and examples/adventure.sh, with output at examples/adventure-transcript.txt, for many examples.

Note there is no code (yet) in this repo. Only documentation and examples for now.

Here's a quick example. To run this example yourself, you'd need an API key ($TEO_AUTH), which you probably don't have.

curl -s -H "X-TEO-Authorization: $TEO_AUTH" \
     -X POST https://api.tetls.net/tlsp \
     -d '{
        "url": "https://postman-echo.com/time/now",
        "method": "GET",
        "headers": {
          "Content-Type": "application/json"
        }}' |
    tee test.json |
    jq -r .parsed_response_body.body

cat test.json | jq .
