iOS加密之MD5加密

话不多说，上代码！

MyMD5.h里面

#import <Foundation/Foundation.h> @interface MyMD5 : NSObject { } +(NSString *) md5: (NSString *) inPutText ; @end

MyMD5.m里面

#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); 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] ] lowercaseString]; } @end
