Md5加密

app安全很重要，MD5保障

//  Md5.h
#import <Foundation/Foundation.h>

@interface Md5 : NSObject
+ (NSString *)md5:(NSString *)inPutText;
@end

 

//
//  Md5.m


#import "Md5.h"

#import <CommonCrypto/CommonDigest.h>
@implementation Md5
+(NSString *) md5: (NSString *) inPutText
{
    const char *cStr = [inPutText UTF8String];
    unsigned char result[CC_MD5_DIGEST_LENGTH];
    CC_MD5(cStr, strlen(cStr), result);
    
    return [[NSString stringWithFormat:@"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X",
             result[0], result[1], result[2], result[3],
             result[4], result[5], result[6], result[7],
             result[8], result[9], result[10], result[11],
             result[12], result[13], result[14], result[15]
             ] lowercaseString];
}
@end

 

新控制器中调用之前，加入头文件

调用  NSLog(@"_%@",[Md5 md5:@"1381878604212345678ios"]);
