# @oslojs/crypto documentation

**Documentation: https://crypto.oslojs.dev**

A basic JavaScript crypto library by [Oslo](https://oslojs.dev). Includes APIs for SHA-1, SHA-2, SHA-3, HMAC, ECDSA, RSA, and cryptographically secure random generator.

- Runtime-agnostic
- No third-party dependencies
- Fully typed

Algorithms such as SHA and ECDSA are tested against NIST test vectors.

## Installation

```
npm i @oslojs/crypto
```

What are git dependencies?

Git dependency

Contains a dependency which resolves to a GitHub URL. Dependencies fetched from GitHub specifiers are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are GitHub dependencies?
