# WebCrypto Key Utilities
[](https://jsr.io/@maks11060/crypto)
[](https://github.com/MAKS11060/crypto/actions/workflows/ci.yml)
A lightweight library for working with WebCrypto keys: generate, import, export, and convert cryptographic keys and key
pairs in various formats.
## Features
- Generate cryptographic key pairs for modern algorithms
- Import and export keys and key pairs in `hex`, `raw`, and `jwk` formats
- Convert between supported formats
- Supports `Ed25519`, `X25519`, `P-256`, `P-384`, `P-521`, and `RSASSA-PKCS1-v1_5`
## Install
```ts
// deno add jsr:@maks11060/crypto
import {generateKeyPair} from '@maks11060/crypto'
// or
import {generateKeyPair} from 'jsr:@maks11060/crypto'
```
## Usage
```ts
import {exportKey, generateKeyPair, importKey, importKeyPair} from '@maks11060/crypto'
const keys = await generateKeyPair('Ed25519')
keys.privateKey // CryptoKey
keys.publicKey // CryptoKey
// export key pair
const {privateKey, publicKey} = await exportKey('hex', keys)
console.log(privateKey) // e6cc65db53dcdce37d095c5bd792a5114e8ca575190979dfaea1afa6da1daef9
console.log(publicKey) // b504196a380c1dcb0526c88df4f947b8d8e32f3e7a5ac57d852f439fc4fc80bc
// export single key
const privateKey_2 = await exportKey('hex', keys.privateKey)
const publicKey_2 = await exportKey('hex', keys.publicKey)
console.log(privateKey_2) // e6cc65db53dcdce37d095c5bd792a5114e8ca575190979dfaea1afa6da1daef9
console.log(publicKey_2) // b504196a380c1dcb0526c88df4f947b8d8e32f3e7a5ac57d852f439fc4fc80bc
// import private key
await importKey('hex', {alg: 'Ed25519', publicKey, privateKey})
// import public key
await importKey('hex', {alg: 'Ed25519', publicKey})
// import key pair
await importKeyPair('hex', {alg: 'Ed25519', publicKey, privateKey})
```
### Import / Export
| Algorithm | exportKey(format) | importKey(format) |
| :-----------------: | :----------------------: | :----------------------: |
| `Ed25519` | `raw`, `hex`, `jwk` | `raw`, `hex`, `jwk` |
| `X25519` | `raw`, `hex`, `jwk` | `raw`, `hex`, `jwk` |
| `P-256`, `ES256` | `raw`, `hex`, `jwk` | `raw`, `hex`, `jwk` |
| `P-384`, `ES384` | `raw`, `hex`, `jwk` | `raw`, `hex`, `jwk` |
| `P-521`, `ES512` | [^1] `raw`, `hex`, `jwk` | [^1] `raw`, `hex`, `jwk` |
| | | |
| `RSASSA-PKCS1-v1_5` | `jwk` | `jwk` |
| `RSA-PSS` | `jwk` | `jwk` |
