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;

+ (NSString*)encodeBase64String:(NSString * )input {
    NSData *data = [input dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    data = [GTMBase64 encodeData:data];
    NSString *base64String = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    return base64String;
}

+ (NSString*)decodeBase64String:(NSString * )input {
    NSData *data = [input dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    data = [GTMBase64 decodeData:data];
    NSString *base64String = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    return base64String;
}

+ (NSString*)encodeBase64Data:(NSData *)data {
    data = [GTMBase64 encodeData:data];
    NSString *base64String = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    return base64String;
}

+ (NSString*)decodeBase64Data:(NSData *)data {
    data = [GTMBase64 decodeData:data];
    NSString *base64String = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    return base64String;
}

//    BASE64加密
    NSString *baseEncodeString = [GTMBase64 encodeBase64String:password];
    NSString *baseDecodeString = [GTMBase64 decodeBase64String:baseEncodeString];
    NSLog(@"baseEncodeString = %@",baseEncodeString);
    NSLog(@"baseDecodeString = %@",baseDecodeString);
