+
+## Usage
+
+Storing your sensitive data in the keychain can take up a lot of time and effort. It should be easy to just drop something in there and retrive it with a few simple lines of code. DDDKeychainWrapper offers this simplicity and here is how we do it: 
+
+```objective-c
+	// Writing to the Keychain
+	[DDDKeychainWrapper setString:@"Secret string" forKey:@"my_key"];
+    
+    // Reading from the Keychain
+    NSString *secretString = [DDDKeychainWrapper stringForKey:@"my_key"];
+```
+
+DDDKeychainWrapper has support for the following types
+
+* NSString
+* NSDate
+* NSData
+* NSArray
+* NSDictionary
+* NSNumber
+* BOOL
+* Objects (Must confirm to NSCoding)
+
+A method for wiping the keychain data inserted via the wrapper exists as well.
+
+## Installation
+
+DDDKeychainWrapper is available through [CocoaPods](http://cocoapods.org). To install
+it, simply add the following line to your Podfile:
+
+    pod "DDDKeychainWrapper"

-Expecta Matchers for FBSnapshotTestCase
-=======================================
-
-[Expecta](https://github.com/specta/expecta) matchers for [ios-snapshot-test-case](https://github.com/facebook/ios-snapshot-test-case).
-
-[![Build Status](https://travis-ci.org/dblock/ios-snapshot-test-case-expecta.png)](https://travis-ci.org/dblock/ios-snapshot-test-case-expecta)
-
-### Usage
-
-Add `Expecta+Snapshots` to your Podfile, the latest `FBSnapshotTestCase` will come in as a dependency.
-
-``` ruby
-pod 'Expecta+Snapshots'
-```
-
-### App setup
-
-Use `expect(view).to.recordSnapshotNamed(@"unique snapshot name")` to record a snapshot and `expect(view).to.haveValidSnapshotNamed(@"unique snapshot name")` to check it.
-
-If you project was compiled with Specta included, you have two extra methods that use the spec hierarchy to generate the snapshot name for you: `recordSnapshot()` and `haveValidSnapshot()`. You should only call these once per `it()` block.
-
-If you need the `usesDrawViewHierarchyInRect` property in order to correctly render UIVisualEffect, UIAppearance and Size Classes, call `[Expecta setUsesDrawViewHierarchyInRect:NO];` inside `beforeAll`.
-
-``` Objective-C
-#define EXP_SHORTHAND
-#include <Specta/Specta.h>
-#include <Expecta/Expecta.h>
-#include <Expecta+Snapshots/EXPMatchers+FBSnapshotTest.h>
-#include "FBExampleView.h"
-
-SpecBegin(FBExampleView)
-
-describe(@"manual matching", ^{
-
-    it(@"matches view", ^{
-        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
-        expect(view).to.recordSnapshotNamed(@"FBExampleView");
-        expect(view).to.haveValidSnapshotNamed(@"FBExampleView");
-    });
-
-    it(@"doesn't match a view", ^{
-        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
-        expect(view).toNot.haveValidSnapshotNamed(@"FBExampleViewDoesNotExist");
-    });
-
-});
-
-describe(@"test name derived matching", ^{
-
-    it(@"matches view", ^{
-        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
-        expect(view).to.recordSnapshot();
-        expect(view).to.haveValidSnapshot();
-    });
-
-    it(@"doesn't match a view", ^{
-        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
-        expect(view).toNot.haveValidSnapshot();
-    });
-
-});
-
-SpecEnd
-```
-
-### Sane defaults
-
-`EXPMatchers+FBSnapshotTest` will automatically figure out the tests folder, and [add a reference image](https://github.com/dblock/ios-snapshot-test-case-expecta/blob/master/EXPMatchers%2BFBSnapshotTest.m#L84-L85) directory, if you'd like to override this, you should include a `beforeAll` block setting the `setGlobalReferenceImageDir` in each file containing tests.
-
-```
-beforeAll(^{
-    setGlobalReferenceImageDir(FB_REFERENCE_IMAGE_DIR);
-});
-```
-
-
-### Example
-
-A complete project can be found in [FBSnapshotTestCaseDemo](FBSnapshotTestCaseDemo).
-
-Notably, take a look at [FBSnapshotTestCaseDemoSpecs.m](FBSnapshotTestCaseDemo/FBSnapshotTestCaseDemoTests/FBSnapshotTestCaseDemoSpecs.m) for a complete example, which is an expanded Specta version version of [FBSnapshotTestCaseDemoTests.m](https://github.com/facebook/ios-snapshot-test-case/blob/master/FBSnapshotTestCaseDemo/FBSnapshotTestCaseDemoTests/FBSnapshotTestCaseDemoTests.m).
-
-Finally you can consult the tests for [ARTiledImageView](https://github.com/dblock/ARTiledImageView/tree/master/IntegrationTests) or [NAMapKit](https://github.com/neilang/NAMapKit/tree/master/Demo/DemoTests).

-FBSnapshotTestCase
-======================
-
-[![Build Status](https://travis-ci.org/facebook/ios-snapshot-test-case.svg)](https://travis-ci.org/facebook/ios-snapshot-test-case) [![Cocoa Pod Version](https://cocoapod-badges.herokuapp.com/v/FBSnapshotTestCase/badge.svg)](http://cocoadocs.org/docsets/FBSnapshotTestCase/)
-
-What it does
-------------
-
-A "snapshot test case" takes a configured `UIView` or `CALayer` and uses the
-`renderInContext:` method to get an image snapshot of its contents. It
-compares this snapshot to a "reference image" stored in your source code
-repository and fails the test if the two images don't match.
-
-Why?
-----
-
-At Facebook we write a lot of UI code. As you might imagine, each type of
-feed story is rendered using a subclass of `UIView`. There are a lot of edge
-cases that we want to handle correctly:
-
-- What if there is more text than can fit in the space available?
-- What if an image doesn't match the size of an image view?
-- What should the highlighted state look like?
-
-It's straightforward to test logic code, but less obvious how you should test
-views. You can do a lot of rectangle asserts, but these are hard to understand
-or visualize. Looking at an image diff shows you exactly what changed and how
-it will look to users.
-
-We developed `FBSnapshotTestCase` to make snapshot tests easy.
-
-Installation with CocoaPods
----------------------------
-
-1. Add the following lines to your Podfile:
-
-     ```
-     target "Tests" do
-       pod 'FBSnapshotTestCase'
-     end
-     ```
-
-   If you support iOS 7 use `FBSnapshotTestCase/Core` instead, which doesn't contain Swift support.
-
-   Replace "Tests" with the name of your test project.
-
-2. There are [three ways](https://github.com/facebook/ios-snapshot-test-case/blob/master/FBSnapshotTestCase/FBSnapshotTestCase.h#L19-L29) of setting reference image directories, the recommended one is to define `FB_REFERENCE_IMAGE_DIR` in your scheme. This should point to the directory where you want reference images to be stored. At Facebook, we normally use this:
-
-|Name|Value|
-|:---|:----|
-|`FB_REFERENCE_IMAGE_DIR`|`$(SOURCE_ROOT)/$(PROJECT_NAME)Tests/ReferenceImages`|
-
-
-![](FBSnapshotTestCaseDemo/Scheme_FB_REFERENCE_IMAGE_DIR.png)
-
-Creating a snapshot test
-------------------------
-
-1. Subclass `FBSnapshotTestCase` instead of `XCTestCase`.
-2. From within your test, use `FBSnapshotVerifyView`.
-3. Run the test once with `self.recordMode = YES;` in the test's `-setUp`
-   method. (This creates the reference images on disk.)
-4. Remove the line enabling record mode and run the test.
-
-Features
---------
-
-- Automatically names reference images on disk according to test class and
-  selector.
-- Prints a descriptive error message to the console on failure. (Bonus:
-  failure message includes a one-line command to see an image diff if
-  you have [Kaleidoscope](http://www.kaleidoscopeapp.com) installed.)
-- Supply an optional "identifier" if you want to perform multiple snapshots
-  in a single test method.
-- Support for `CALayer` via `FBSnapshotVerifyLayer`.
-- `usesDrawViewHierarchyInRect` to handle cases like `UIVisualEffect`, `UIAppearance` and Size Classes.
-- `isDeviceAgnostic` to allow appending the device model (`iPhone`, `iPad`, `iPod Touch`, etc), OS version and screen size to the images (allowing to have multiple tests for the same «snapshot» for different `OS`s and devices).
-
-Notes
------
-
-Your unit test must be an "application test", not a "logic test." (That is, it
-must be run within the Simulator so that it has access to UIKit.) In Xcode 5
-and later new projects only offer application tests, but older projects will
-have separate targets for the two types.

+NAChloride
+===========
+
+This project wraps [libsodium](https://github.com/jedisct1/libsodium) for:
+
+* Secure Memory
+* Random Data
+* Secret-Key 
+  * Authenticated Encryption
+  * Authentication
+  * AEAD
+* Public-Key
+  * Authenticated Encryption
+* One-Time Authentication
+* Password Hashing: *Scrypt*
+* Stream Ciphers: *XSalsa20*
+
+More wrappers are coming soon.
+
+Do you want to work on crypto at Keybase? [We're hiring](https://keybase.io/jobs).
+
+If you are looking for other non-libsodium related crypto (that used to be here), see [NACrypto](https://github.com/gabriel/NACrypto).
+
+# Podfile
+
+```ruby
+pod "NAChloride"
+```
+
+# Init
+
+You should call `NAChlorideInit()` to initialize on app start. It is thread safe and multiple calls are ignored. We automatically call this as well as a safety measure.
+
+```objc
+NAChlorideInit();
+```
+
+# Secure Memory
+
+See [Securing Memory Allocations](https://download.libsodium.org/doc/helpers/memory_management.html).
+
+```objc
+NASecureData *secureData = [NASecureData secureReadOnlyDataWithLength:length completion:^(void *bytes, NSUInteger length) {
+  // Set the bytes here. After this it will be read-only.
+}];
+
+// After the block executes, secureData is read-only. You can set it to no access (or read/write).
+// If you set it to no access and secureData.bytes is accessed, it will SIGABRT. For example,
+// secureData.protection = NASecureDataProtectionNoAccess;
+```
+
+Some classes like NASecretBox, NABox and NAAEAD have an option to enable secureMemory (on decrypt).
+
+NASecureData subclasses NSMutableData for compatibility and usage with other APIs.
+
+# Generating Random Data
+
+See [Generating Random Data](https://download.libsodium.org/doc/generating_random_data/index.html).
+
+```objc
+NSData *data = [NARandom randomData:32]; // 32 bytes of random data
+NSData *data = [NARandom randomSecureReadOnlyData:32]; // 32 bytes of random, secure, read-only data
+```
+
+# Secret-Key Cryptography
+
+## Authenticated Encryption
+
+Encrypts and authenticates a message using a shared key and nonce.
+
+See [Authenticated Encryption](https://download.libsodium.org/doc/secret-key_cryptography/authenticated_encryption.html).
+
+```objc
+NSData *key = [NARandom randomData:NASecretBoxKeySize];
+NSData *nonce = [NARandom randomData:NASecretBoxNonceSize];
+NSData *message = [@"This is a secret message" dataUsingEncoding:NSUTF8StringEncoding];
+
+NASecretBox *secretBox = [[NASecretBox alloc] init];
+NSError *error = nil;
+NSData *encrypted = [secretBox encrypt:message nonce:nonce key:key error:&error];
+// If an error occurred encrypted will be nil and error set
+
+NSData *decrypted = [secretBox decrypt:encrypted nonce:nonce key:key error:&error];
+```
+
+## Authentication
+
+See [Authentication](https://download.libsodium.org/doc/secret-key_cryptography/secret-key_authentication.html).
+
+```objc
+NSData *key = [NARandom randomData:NAAuthKeySize];
+NSData *message = [@"This is a message" dataUsingEncoding:NSUTF8StringEncoding];
+
+NSError *error = nil;
+NAAuth *auth = [[NAAuth alloc] init];
+NSData *authData = [auth auth:message key:key &error];
+BOOL verified = [auth verify:authData data:message key:key error:&error];
+```
+
+## AEAD
+
+See [Authenticated Encryption with Additional Data](https://download.libsodium.org/doc/secret-key_cryptography/aead.html).
+
+```objc
+NSData *key = [NARandom randomData:NAAEADKeySize];
+NSData *nonce = [NARandom randomData:NAAEADNonceSize];
+NSData *message = [@"This is a secret message" dataUsingEncoding:NSUTF8StringEncoding];
+NSData *additionalData = [@"Additional data" dataUsingEncoding:NSUTF8StringEncoding];
+
+NAAEAD *AEAD = [[NAAEAD alloc] init];
+NSError *error = nil;
+NSData *encryptedData = [AEAD encryptChaCha20Poly1305:message nonce:nonce key:key additionalData:additionalData error:&error];
+NSData *decryptedData = [AEAD decryptChaCha20Poly1305:encryptedData nonce:nonce key:key additionalData:additionalData error:&error];
+```
+
+# Public-Key Cryptography
+
+## Authenticated Encryption
+
+See [Authenticated Encryption](https://download.libsodium.org/doc/public-key_cryptography/authenticated_encryption.html).
+
+```objc
+NSError *error = nil;
+NABoxKeypair *keypair = [NABoxKeypair generate:&error];
+
+NSData *nonce = [NARandom randomData:NABoxNonceSize];
+NSData *message = [@"This is a secret message" dataUsingEncoding:NSUTF8StringEncoding];
+
+NABox *box = [[NABox alloc] init];
+NSData *encryptedData = [box encrypt:message nonce:nonce keypair:keypair error:&error];
+NSData *decryptedData = [box decrypt:encryptedData nonce:nonce keypair:keypair error:&error];
+```
+
+# Password Hashing
+
+See [Password Hashing](https://download.libsodium.org/doc/password_hashing/index.html).
+
+```objc
+NSData *key = [@"toomanysecrets" dataUsingEncoding:NSUTF8StringEncoding];
+NSData *salt = [NARandom randomData:NAScryptSaltSize];
+NSError *error = nil;
+NSData *data = [NAScrypt scrypt:key salt:salt error:&error];
+```
+
+# Advanced
+
+## One-Time Authentication
+
+Generates a MAC for a given message and shared key using Poly1305 algorithm.
+Key may NOT be reused across messages.
+
+See [One-Time Authentication](https://download.libsodium.org/doc/advanced/poly1305.html).
+
+```objc
+NSData *key = [NARandom randomData:NAOneTimeAuthKeySize];
+NSData *message = [@"This is a message" dataUsingEncoding:NSUTF8StringEncoding];
+
+NSError *error = nil;
+NAOneTimeAuth *oneTimeAuth = [[NAOneTimeAuth alloc] init];
+NSData *auth = [oneTimeAuth auth:message key:key error:&error];
+BOOL verified = [oneTimeAuth verify:auth data:message key:key error:&error];
+```
+
+## Stream Ciphers
+
+See [XSalsa20](https://download.libsodium.org/doc/advanced/xsalsa20.html).
+
+```objc
+NSData *key = [NARandom randomData:NAStreamKeySize];
+NSData *nonce = [NARandom randomData:NAStreamNonceSize];
+NAStream *stream = [[NAStream alloc] init];
+NSError *error = nil;
+NSData *encrypted = [stream xor:message nonce:nonce key:key error:&error];
+NSData *decrypted = [stream xor:encrypted nonce:nonce key:key error:&error];
+```
+
+## Dispatch
+
+There is a helper to dispatch these operations on a queue:
+
+```objc
+dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
+NADispatch(queue, ^id(NSError **error) {
+  return [NAScrypt scrypt:password salt:salt error:error];
+}, ^(NSError *error, NSData *data) {
+  // This is on the main queue.
+  // Error is set if it failed.
+});
+```
