sixteen / tlsnutils

Solidity Library for parsing and verifying TLS-N proofs.

TLS-N Utility Library

Overview

This library allows the verification and parsing of TLS-N proofs. This version supports proofs with chunk-level granularity signed by a TLS certificate using secp256r1. The TLS-N Utility Library makes use of solidity-bytesutils to parse the proofs.

Examples

Verifying a proof

	bytes memory proof = '\x20\x00\x10....
	bool res = tlsnutils.verifyProof(proof);

Getting the generator's response

    bytes memory proof = '\x20\x00\x10....
	bytes memory response = tlsnutils.getResponse(proof);

Getting the requested URL in case of HTTP

    bytes memory proof = '\x20\x00\x10....
	bytes memory url = tlsnutils.getHTTPRequestURL(proof);

Getting the generator's HTTP body (the HTTP response) in case of HTTP

    bytes memory proof = '\x20\x00\x10....
    bytes memory body = tlsnutils.getHTTPBody(proof);
