## API ## 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 - `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. 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 - `curve: String`, one of `'P-256'`, `'P-384'`, `'P-521'` is currently supported
