MD5加密

参考:http://blog.csdn.net/u011349387/article/details/47318679

1、导入头文件:

#import <CommonCrypto/CommonDigest.h>

 

2、MD5加密处理

/**

 *  对密码进行MD5加密

 */

-(NSString *)passwordMD5HexDigest:(NSString *)password{

    if(password == nil){

        return nil;

    }

    const char* str = [password UTF8String];

    unsigned char result[CC_MD5_DIGEST_LENGTH];

    CC_MD5(str, (CC_LONG)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[i]];

    }

    return key;

}
