一行代码实现 iOS Base64, 32/16位 MD5, DES, AES, RSA 算法，操作简单好用。(Achieves Base64, 32/16 bit MD5, DES, AES and RSA algorithms for iOS with one line of code, the operation is simple and easy to use.)
Using CocoaPods:
pod 'DYFCryptoUtils', '~> 1.0.2'

#define PlainText @"Objective-C，通常写作ObjC或OC和较少用的Objective C或Obj-C，是扩充C的面向对象编程语言。它主要使用于Mac OS X和GNUstep这两个使用OpenStep标准的系统，而在NeXTSTEP和OpenStep中它更是基本语言。GCC与Clang含Objective-C的编译器，Objective-C可以在GCC以及Clang运作的系统上编译。Swift是苹果于2014年WWDC（苹果开发者大会）发布的一种新的编程语言，用于编写 iOS 和 macOS 应用。Swift 结合了 C 和 Objective-C 的优点并且不受C兼容性的限制。Swift 采用安全的编程模式并添加了很多新特性，这将使编程更简单，更灵活，也更有趣。Swift 是基于成熟而且倍受喜爱的 Cocoa 和 Cocoa Touch 框架，他的降临将重新定义软件开发。"
