crypto-encoder

A simple hypercore-compatible crypto encoder.

Example

const hypercore = require('hypercore')
const Encoder = require('.')

const encryptionKey = Encoder.encryptionKey()
const nonce = Encoder.generateNonce()
const valueEncoding = Encoder(encrytionKey, { nonce, valueEncoding: 'utf-8' })

const feed = hypercore(storage, { valueEncoding })

API

const Encoder = require('.')

const encryptionKey = Encoder.encryptionKey()

Generate a random 32 byte key to be used to encrypt.

const nonce = Encoder.generateNonce()

Generate a random nonce used to encrypt.

const valueEncoding = Encoder(encryptionKey, opts)

Returns a message encoder used for encrypting messages in hypercore.

• encryptionKey must be a buffer of length Encoder.KEYBYTES.
• opts is an optional object which may contain:
  • ops.nonce a buffer containing a 24 byte nonce
  • opts.valueEncoder, an additional encoder to be used before encryption. May be one of:
    • The string 'utf-8' - utf-8 encoded strings will be assumed.
    • The string 'JSON' - JSON encoding will be assumed.
    • A custom encoder of the form { encode: [function] decode: [function] }
