> Support for secp256k1 keys in js-libp2p-crypto
|
||||
|
||||
This repo contains a [js-libp2p-crypto](https://github.com/libp2p/js-libp2p-crypto)-compatible
|
||||
implementation of cryptographic signature generation and verification using the
|
||||
[secp256k1 elliptic curve](https://en.bitcoin.it/wiki/Secp256k1) popularized by Bitcoin and other
|
||||
crypto currencies.

## Install
|
||||
|
||||
```sh
|
||||
npm install --save libp2p-crypto-secp256k1
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
This module is designed to work with [js-libp2p-crypto](https://github.com/libp2p/js-libp2p-crypto).
|
||||
Installing `libp2p-crypto-secp256k1` will automatically add support for the `'secp256k1'` key type, which
|
||||
can be used as an argument to the [libp2p-crypto API functions](https://github.com/libp2p/js-libp2p-crypto#api)
|
||||
`generateKeyPair`, `unmarshalPublicKey`, and `marshalPrivateKey`. The keys returned from those functions will be
|
||||
instances of the `Secp256k1PublicKey` or `Secp256k1PrivateKey` classes provided by this module.
|
||||
|
||||
### Example
|
||||
|
||||
```js
|
||||
const crypto = require('libp2p-crypto')
|
||||
|
||||
const msg = Buffer.from('Hello World')
|
||||
|
||||
crypto.generateKeyPair('secp256k1', 256, (err, key) => {
|
||||
// assuming no error, key will be an instance of Secp256k1PrivateKey
|
||||
// the public key is available as key.public
|
||||
key.sign(msg, (err, sig) => {
|
||||
key.public.verify(msg, sig, (err, valid) => {
|
||||
assert(valid, 'Something went horribly wrong')
|
||||
})
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
The functions below are the public API of this module.
|
||||
For usage within libp2p-crypto, see the [libp2p-crypto API documentation](https://github.com/libp2p/js-libp2p-crypto#api).
|
||||
|
||||
### `generateKeyPair([bits, ] callback)`
|
||||
- `bits: Number` - Optional, included for compatibility with js-libp2p-crypto. Ignored if present; private keys will always be 256 bits.
|
||||
- `callback: Function`
|
||||
|
||||
### `unmarshalSecp256k1PublicKey(bytes)`
|
||||
- `bytes: Buffer`
|
||||
|
||||
Converts a serialized secp256k1 public key into an instance of `Secp256k1PublicKey` and returns it
|
||||
|
||||
### `unmarshalSecp256k1PrivateKey(bytes, callback)`
|
||||
- `bytes: Buffer`
|
||||
- `callback: Function`
|
||||
|
||||
Converts a serialized secp256k1 private key into an instance of `Secp256k1PrivateKey`, passing it to `callback` on success
|
||||
|
||||
### `Secp256k1PublicKey`
|
||||
|
||||
#### `.verify(data, sig, callback)`
|
||||
- `data: Buffer`
|
||||
- `sig: Buffer`
|
||||
- `callback: Function`
|
||||
|
||||
Calculates the SHA-256 hash of `data`, and verifies the DER-encoded signature in `sig`, passing the result to `callback`
|
||||
|
||||
### `Secp256k1PrivateKey`
|
||||
|
||||
#### `.public`
|
||||
|
||||
Accessor for the `Secp256k1PublicKey` associated with this private key.
|
||||
|
||||
#### `.sign(data, callback)`
|
||||
- `data: Buffer`
|
||||
|
||||
Calculates the SHA-256 hash of `data` and signs it, passing the DER-encoded signature to `callback`
