-# Encryption
-
-OrbitDB features a modular architecture for database encryption. By passing a  module to an OrbitDB database, different encryption methods can be employed.
-
-OrbitDB project currently maintains a [SimpleEncryption](https://github.com/orbitdb/simple-encryption) module that can be used to get started with encrypted databases.
-
-**WARNING:** SimpleEncryption is an unaudited encryption module. Use at your own risk.
-
-## How it works
-
-OrbitDB encrypts databases in two layers: encrypting the payload and encrypting the log entry.
-
-Log entry encryption encrypts each log entry fully. Payload encryption encrypts just the value.
-
-This makes it possible to separate users of a database and replicators of a database, ie. an orbitdb peer can replicate a database without being able to decrypt the payloads (=data) of the database.
-
-## Configuring encryption
-
-You can configure OrbitDB to encrypt either the payload data being stored or the entire database.
-
-To ***encrypt payload data only***, specify an encryption module and pass it to OtbiDB via the encryption object using the `data` property:
-
-```
-const data = await EncryptionModule()
-const encryption = { data }
-const db = await orbitdb.open(dbNameOrAddress, { encryption })
-```
-
-To ***encrypt the database log entries***, specify an encryption module and pass it to OrbitDB via the encryption object using the `replication` property:
-
-```
-const replication = await EncryptionModule()
-const encryption = { replication }
-const db = await orbitdb.open(dbNameOrAddress, { encryption })
-```
-
-To ***encrypt the whole database***, payload data and oplog entries separately, specify an encryption module and pass it to OrbitDB via the encryption object using both the `replication` and `data` properties:
-
-```
-const replication = await EncryptionModule()
-const data = await EncryptionModule()
-const encryption = { replication, data }
-const db = await orbitdb.open(dbNameOrAddress, { encryption })
-```
-
-## Encrypting Databases
-
-OrbitDB provides simple password-based encryption via an external module called [SimpleEncryption](https://github.com/orbitdb/simple-encryption).
-
-**WARNING:** This is an unaudited encryption module. Use at your own risk.
-
-To install SimpleEncryption:
-
-```
-npm i @orbitdb/simple-encryption
-```
-
-To use encryption, initiate SimpleEncryption with a password and pass it to OrbitDB when opening your database:
-
-```js
-import { SimpleEncryption } from '@orbitdb/simple-encryption'
-
-const replication = await SimpleEncryption({ password: 'hello' })
-const data = await SimpleEncryption({ password: 'world' })
-
-const encryption = { data, replication }
-
-const db = await orbitdb.open(dbNameOrAddress, { encryption })
-```
-
-If you wish to use another encryption type, simply replace SimpleEncryption with the module of your choice.
-
-## Custom Encryption
-
-To implement a custom encryption module for OrbitDB, expose encrypt and decrypt functions:
-
-```
-const CustomEncryption = async () => {
-  const encrypt = (value) => {
-    // return encrypted value
-  }
-
-  const decrypt = (value) => {
-    // return decrypted value
-  }
-
-  return {
-    encrypt,
-    decrypt
-  }
-}
-
-export default CustomEncryption

 OrbitDB is a serverless, distributed, peer-to-peer database. OrbitDB uses IPFS
 as its data storage and Libp2p Pubsub to automatically sync databases with peers. It's an eventually consistent database that uses Merkle-CRDTs for conflict-free database writes and merges making OrbitDB an excellent choice for p2p and decentralized apps, blockchain applications and local first web applications.
