[`ssri2`](https://github.com/cijiugechu/ssri2)(Standard Subresource

Integrity) is a Rust library for parsing, manipulating, serializing,

generating, and verifying [Subresource Integrity](https://w3c.github.io/webappsec/specs/subresourceintegrity/)

hashes.

## Example

Parse a string as [`Integrity`](struct.Integrity.html) to convert it to a struct:

```rust

use ssri2::Integrity;

let source = "sha256-uU0nuZNNPgilLlLX2n2r+sSE7+N6U4DukIj3rOLvzek=";

let parsed: Integrity = source.parse().unwrap();

assert_eq!(parsed.to_string(), source)

```

Generating a new hash from file data:

```rust

use ssri2::Integrity;

// By default, generates Integrity as Sha256.

// Use IntegrityOpts to pick the algorithm yourself.

let sri = Integrity::from(b"hello world");

assert_eq!(sri.to_string(), "sha256-uU0nuZNNPgilLlLX2n2r+sSE7+N6U4DukIj3rOLvzek=");

```

Verifying data against an SRI:

```rust

use ssri2::{Integrity, Algorithm};

let sri = Integrity::from(b"hello world");

assert_eq!(sri.check(b"hello world").unwrap(), Algorithm::Sha256);

```

You can also use [`IntegrityOpts`](struct.IntegrityOpts.html) and [`IntegrityChecker`](struct.IntegrityChecker.html) to generate

and check subresource integrity, respectively. These allow things like multiple algorithms, and

incremental/streamed data input.

## Documentation

- [API Docs](https://docs.rs/ssri2)

## Features

- Parses and stringifies [Subresource Integrity](https://w3c.github.io/webappsec/specs/subresourceintegrity/) strings.

- Generates SRI strings from raw data.

- Strict standard compliance.

- Multiple entries for the same algorithm.
