## API
|
||||
|
||||
### `generateKeyPair(type, bits)`
|
||||
### `hmac`
|
||||
|
||||
Exposes an interface to the Keyed-Hash Message Authentication Code (HMAC) as defined in U.S. Federal Information Processing Standards Publication 198. An HMAC is a cryptographic hash that uses a key to sign a message. The receiver verifies the hash by recomputing it using the same key.
|
||||
|
||||
#### `create(hash, secret, callback)`
|
||||
|
||||
- `hash: String`
|
||||
- `secret: Buffer`
|
||||
- `callback: Function`
|
||||
|
||||
##### `digest(data, callback)`
|
||||
|
||||
- `data: Buffer`
|
||||
- `callback: Function`
|
||||
|
||||
### `aes`
|
||||
Expoes an interface to AES encryption (formerly Rijndael), as defined in U.S. Federal Information Processing Standards Publication 197.
|
||||
|
||||
This uses `CTR` mode.
|
||||
|
||||
#### `create(key, iv, callback)`
|
||||
|
||||
- `key: Buffer` The key, if length `16` then `AES 128` is used. For length `32`, `AES 256` is used.
|
||||
- `iv: Buffer` Must have length `16`.
|
||||
- `callback: Function`
|
||||
|
||||
##### `encrypt(data, callback)`
|
||||
|
||||
- `data: Buffer`
|
||||
- `callback: Function`
|
||||
|
||||
##### `encrypt(data, callback)`
|
||||
|
||||
- `data: Buffer`
|
||||
- `callback: Function`
|
||||
|
||||
|
||||
### `webcrypto`
|
||||
|
||||
Depending on the environment this is either an instance of [node-webcrypto-ossl](https://github.com/PeculiarVentures/node-webcrypto-ossl) or the result of `window.crypto`.
|
||||
|
||||
### `keys`
|
||||
|
||||
### `generateKeyPair(type, bits, callback)`
|
||||
|
||||
- `type: String`, only `'RSA'` is currently supported
|
||||
- `bits: Number`
|
||||
- `bits: Number` Minimum of 1024
|
||||
- `callback: Function`
|
||||
|
||||
Generates a keypair of the given type and bitsize.
|
||||
|
||||
### `generateEphemeralKeyPair(curve)`
|
||||
### `generateEphemeralKeyPair(curve, callback)`
|
||||
|
||||
- `curve: String`, one of `'P-256'`, `'P-384'`, `'P-521'` is currently supported
|
||||
- `callback: Function`
|
||||
|
||||
Generates an ephemeral public key and returns a function that will compute the shared secret key.
|
||||
|
||||
