var encryption = require('sodium-encryption')
var key = encryption.key()
var nonce = encryption.nonce()

`
#### key = encryption.key()
Generate a secret key. Returns a 32 byte buffer.
#### nonce = encryption.nonce()
Generate a nonce. Returns a 24 byte buffer.
A nonce can be public and you should use a new one everytime you use a key.
#### box = encryption.encrypt(message, nonce, key)
Encrypts a message.
#### message = encryption.decrypt(box, nonce, key)
Decrypt a message. Returns null is the message cannot be decrypted.
#### keys = encryption.scalarMultiplicationKeyPair([secretKey])
Generate a key pair to be used for scalar multiplication. If you don't pass in a secret key, one will be generated for you.
Returns a key pair consisting of a secret key and a public key.
` js`
{
secretKey:
publicKey:
}
#### sharedKey = encryption.scalarMultiplication(secretKey, otherPublicKey)
Generate a shared key based on a remote public scalar multiplication key and your own secret key.
Returns the same shared key if called with corresponding secret and public key
` js
var keys = encryption.scalarMultiplicationKeyPair()
var otherKeys = encryption.scalarMultiplicationKeyPair()
console.log('shared key', encryption.scalarMultiplication(keys.secretKey, otherKeys.publicKey))
console.log('shared key', encryption.scalarMultiplication(otherKeys.secretKey, keys.publicKey))
