使用说明

1. 原文

   #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。"

2. Base64

   - (void)testBase64 {
   NSString *encodedText = [DYFCryptoUtils base64EncodedStringWithString:PlainText];
   NSLog(@"[Base64] Encoded text: %@", encodedText);
   NSString *decodedText = [DYFCryptoUtils base64DecodedStringWithString:encodedText];
   NSLog(@"[Base64] Decoded text: %@", decodedText);
   }

3. MD5

   - (void)testMD5 {
   NSString *hash = [DYFCryptoUtils MD5EncodedStringWithString:PlainText];
   NSLog(@"[MD5] Hash: %@", hash);
   NSString *hash16Bit = [DYFCryptoUtils MD5EncodedStringFor16BitWithString:PlainText];
   NSLog(@"[MD5] 16 bit hash: %@", hash16Bit);
   }

4. DES

   - (void)testDES {
   NSString *key = @"aT59qMrbqJh3o7F566GpO6BhKgdrHDUsMfIPs27J5CmE6DXGkl9VFYam4gRI5MFVjFTi9oScQALesTaPuQ8hdAH9jEssJnItgYxE6Pl+D8sFTVZJvhMwNQR";
   // iv为nil.
   NSString *encryptedText = [DYFCryptoUtils DESEncrypt:PlainText key:key];
   NSLog(@"[DES] Encrypted text: %@", encryptedText);
   NSString *decryptedText = [DYFCryptoUtils DESDecrypt:encryptedText key:key];
   NSLog(@"[DES] Decrypted text: %@", decryptedText);
   }

5. AES

   - (void)testAES {
   NSString *key = @"aT59qMrbqJh3o7F566GpO6BhKgdrHDUsMfIPs27J5CmE6DXGkl9VFYam4gRI5MFVjFTi9oScQALesTaPuQ8hdAH9jEssJnItgYxE6Pl+D8sFTVZJvhMwNQR";
   // iv为nil.
   NSString *encryptedText = [DYFCryptoUtils AESEncrypt:PlainText key:key];
   NSLog(@"[AES] Encrypted text: %@", encryptedText);
   NSString *decryptedText = [DYFCryptoUtils AESDecrypt:encryptedText key:key];
   NSLog(@"[AES] Decrypted text: %@", decryptedText);
   }

6. RSA

   // RSA公钥
   static NSString *rsaPubKey = @"MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCmPW2SwJFldGVB1SM82VYvSZYRF1H5DREUiDK2SLnksxHAV/roC1uB44a4siUehJ9AKeV/g58pVrjhX3eSiBh9Khom/S2hEWF2n/6+lqqiwQi1W5rjl86v+dI2F6NgbPFpfesrRjWD9uskT2VX/ZJuMRLz8VPIyQOM9TW3PkMYBQIDAQAB";
