1MD5
创建MD5类
#import <Foundation/Foundation.h> @interface CJMD5 : NSObject +(NSString *)md5HexDigest:(NSString *)input; @end
#import "CJMD5.h" #import <CommonCrypto/CommonDigest.h> @implementation CJMD5 +(NSString *)md5HexDigest:(NSString *)input{ const char* str = [input UTF8String]; unsigned char result[CC_MD5_DIGEST_LENGTH]; CC_MD5(str, strlen(str), result); NSMutableString *ret = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH]; for(int i = 0; i<CC_MD5_DIGEST_LENGTH; i++) { [ret appendFormat:@"%02X",result]; } return ret; } @end
NSString *userName = @"cerastes"; NSString *password = @"hello Word"; // MD5加密 NSString *md5 = [CJMD5 md5HexDigest:password]; NSLog(@"%@",md5);
AES加密开源代码git下载地址
https://github.com/Gurpartap/AESCrypt-ObjC
使用方法
// AES加密 NSString *encryptedData = [AESCrypt encrypt:userName password:password];//加密 NSString *message = [AESCrypt decrypt:encryptedData password:password]; //解密 NSLog(@"加密结果 = %@",encryptedData); NSLog(@"解密结果 = %@",message);

添加如下方法
.h
+ (NSString*)encodeBase64String:(NSString *)input; + (NSString*)decodeBase64String:(NSString *)input; + (NSString*)encodeBase64Data:(NSData *)data; + (NSString*)decodeBase64Data:(NSData *)data;
