# csverifyfiles

A CLI tool to check hashes of files against hashes generated by
[cshashfiles](cshashfiles.md).

## Install

```bash
$ npm install -g chainscript
```

## Usage

```bash
$ csverifyfiles --help

  Usage: csverifyfiles [options] [hashes] [-- chainscript args]

  Options:

    -h, --help         output usage information
    -V, --version      output the version number
    -r, --root <path>  JSON root path
```

## Examples

### Verify files directly against the output of `cshashfiles`

```bash
$ cshashfiles | csverifyfiles
```

Output:

```
Success
```

### Using hashes stored in a Chainscript

Say you had snapshotted hashes from `cshashfiles` like this:

```bash
$ cshashfiles -r content.files -- -s
```

Now you can verify files from that Chainscript. Assuming the Chainscript's
uuid is `chainscript:document:123456789`:

```bash
$ csverifyfiles -r body.content.files -- chainscript:document:123456789
```

Output:

```json
Success
```

Now, if you modify a file:

```bash
$ csverifyfiles -r body.content.files -- chainscript:document:123456789
```

Output:

```json
Mismatch: Chainscript.js
```
