IOS MD5加密

MD5加密百度一下一大堆，但我还是想在这记录下来。

MyMD5.h代码：

#import <Foundation/Foundation.h>


@interface MyMD5 : NSObject {
    
}

+(NSString *) md5: (NSString *) inPutText ;
@end

MyMD5.m代码：

#import "MyMD5.h"
#import "CommonCrypto/CommonDigest.h"

@implementation MyMD5

+(NSString *) md5: (NSString *) inPutText 
{
    const char *cStr = [inPutText UTF8String];
    unsigned char result[CC_MD5_DIGEST_LENGTH];
    CC_MD5(cStr, strlen(cStr), result);
    
    NSMutableString *hash = [NSMutableString string];
    for (int i = 0; i < 16; i++)
    {
        [hash appendFormat:@"%02X", result[i]];
    }
    NSString *mdfiveString = [hash lowercaseString];
   
    return mdfiveString;
}
@end
