iOS开发中加密方式——MD5加密

1、 导入头文件

import <CommonCrypto/CommonDigest.h>


2、加密的方法：

- (NSString *) md5:(NSString *) input {

const char *cStr = [input UTF8String];

unsigned char digest[CC_MD5_DIGEST_LENGTH];

CC_MD5( cStr, strlen(cStr), digest ); // This is the md5 call

NSMutableString *output = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH * 2];

for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++)

[output appendFormat:@"%02x", digest[i]];

return output;

}

3、调用加密方法：

NSString *str = @"123456";

NSString *result = [self md5:str];

NSLog(@"%@",result);
