README
Create proof-of-ownership attestations via a [commitment scheme](https://en.wikipedia.org/wiki/Commitment_scheme).
As an illustration we'll create the attestation for this repository itself:
```shell
$ ./attest --name="Ryan Joseph" --email="[email protected]" --desc="poo-attest" --domain="https://github.com/rpj/poo-attest" --home="https://github.com/rpj/poo-attest"
SHA256 331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4
Wrote "/home/ryan/repos-native/poo-attest/331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4_SHA256.txt"
```
The resuling hash - `331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4` - is the _revealable_ information.
The generated output file is _the commitment_ and must be kept secret until proof-of-ownership is required.
In this case, as we want to illustrate the end-to-end process, we'll reveal [it immediately](./331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4_SHA256.txt):
```shell
$ cat 331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4_SHA256.txt
This document serves to provide proof that Ryan Joseph is the owner of "poo-attest" at https://github.com/rpj/poo-attest.
This attestation is made 1/15/2022, 8:23:18 PM (America/Los_Angeles), and will be housed in perpetuity at/under https://github.com/rpj/poo-attest.

Generated by poo-attest 1.0.3, source file SHA256: b99d12900f46fd17d5726818e1d00189629454e65647b7db9b05d553d3693d23
```
In order to verify ownership, the hash of the commitment is recalculated with the appropriate algorithm:
```shell
$ cat 331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4_SHA256.txt | shasum -a 256 -
331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4 -
```
Importantly, we produce the matching result: `331823878b420ad85e0240483f5b6c44327a5b14ef6ef0911c326999e6f882d4`.
