建立好一個自定義的分類
#import <Foundation/Foundation.h>
#import <CommonCrypto/CommonDigest.h>
@interface NSString (MD5)
- (NSString *)md5:(NSString *)input;
@end
實現方法：
#import "NSString+MD5.h"
@implementation NSString (MD5)
- (NSString *)md5:(NSString *)input
{
constchar *cStr = [input
UTF8String];
unsignedchar digest[CC_MD5_DIGEST_LENGTH];
CC_MD5( cStr, strlen(cStr), digest ); // This is the md5 call
NSMutableString *output = [NSMutableStringstringWithCapacity:CC_MD5_DIGEST_LENGTH * 2];
for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++)
[output appendFormat:@"%02x", digest[i]];
return output;
}
@end
