+# Hash
+
+Vapor makes hashing strings easy.
+
+## Example
+
+To hash a string, use the `hash` class on `Droplet`.
+
+```swift
+let hashed = drop.hash.make("vapor")
+```
+
+## SHA2Hasher
+
+By default, Vapor uses a SHA2Hasher with 256 bits. You can change this by giving the `Droplet` a different hasher.
+
+```swift
+let sha512 = SHA2Hasher(variant: .sha512)
+
+let drop = Droplet(hash: sha512)
+```
+
+### Protocol
+
+You can also create your own hasher. You just need to conform to the `Hash` protocol.
+
+```swift
+public protocol Hash: class {
+    var key: String { get set }
+    func make(_ string: String) -> String
+}
+```
