将字符串进行MD5加密,返回加密后的字符串。
#import <CommonCrypto/CommonDigest.h> // Need to import for CC_MD5 access(引入头文件)
- (NSString *)md5:(NSString *)str
{
const char *cStr = [str UTF8String];
unsigned char result[16];
CC_MD5(cStr, strlen(cStr), result); // This is the md5 call
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]
];
}
