## `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` Minimum of 1024
- `callback: Function`
Generates a keypair of the given type and bitsize.
## `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.
Focuses only on ECDH now, but can be made more general in the future.
Calls back with an object of the form
```js
{
key: Buffer,
genSharedKey: Function
}
```
## `keyStretcher(cipherType, hashType, secret, callback)`
- `cipherType: String`, one of `'AES-128'`, `'AES-256'`, `'Blowfish'`
- `hashType: String`, one of `'SHA1'`, `SHA256`, `SHA512`
- `secret: Buffer`
- `callback: Function`
Generates a set of keys for each party by stretching the shared key.
Calls back with an object of the form
```js
{
k1: {
iv: Buffer,
cipherKey: Buffer,
macKey: Buffer
},
k2: {
iv: Buffer,
cipherKey: Buffer,
macKey: Buffer
}
}
```
## `marshalPublicKey(key[, type], callback)`
- `key: crypto.rsa.RsaPublicKey`
- `type: String`, only `'RSA'` is currently supported
Converts a public key object into a protobuf serialized public key.
## `unmarshalPublicKey(buf)`
- `buf: Buffer`
Converts a protobuf serialized public key into its representative object.
## `marshalPrivateKey(key[, type])`
- `key: crypto.rsa.RsaPrivateKey`
- `type: String`, only `'RSA'` is currently supported
Converts a private key object into a protobuf serialized private key.
## `unmarshalPrivateKey(buf, callback)`
- `buf: Buffer`
- `callback: Function`
Converts a protobuf serialized private key into its representative object.
