Pack CRL to Ethereum

This repo provides example implementation of an approach to place CRL (as Certificate Revocation List) to Ethereum as a set of smart contracts.

Prerequisites

To run this code you'll need:

1. Go
2. Truffle Suite
3. abigen
4. solidity

Steps

• Clone and build repo

$: git clone github.com/kalambet/ethcrl
$: cd ethcrl && go mod download

• Obtain supported solidity compiler

$: cd sol/src && truffle obtain && cd -

• Generate binding contracts with abigen

$: cd sol && ./gen.sh && cd -

• On a separate console run Truffle Develop from <repo_path>/sol/src folder and leave it as is

$: cd sol/src && truffle develop

• Copy the first private key from the provided output
• Build an example code

$: go build cmd/ethcrl.go

• Run binary with previously copied private key

$: ./ethcrl -key <PRIVATE_KEY>

Alternative CRL data

It is possible to test arbitrary CRL certificates, for that --der key can be provided. For example, it is possible to download external CRL file, ex:

wget "http://testca2012.cryptopro.ru/cdp/064b632533662a24381872437a3bb7cbb2cafc73.crl"

And provide it as an input to ethcrl:

./bashcrl -key <PRIVATE_KEY> -der "./064b632533662a24381872437a3bb7cbb2cafc73.crl"

Usage

Usage of ./ethcrl:
  -backend string
    	address to eth node listening on port (default "http://localhost:9545")
  -der string
    	path to DER CRL file
  -key string
    	private key data (default "7b90ee8f413863ae7d1dea2886f3bec462f56ebb22a9bf379a9a76f5de7ba335")
