+# 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.
