MD5 in Xcode

import --> #import CommonCrypto/CommonDigest.h
then make a Class Utility


in .h


#import Foundation/Foundation.h

#import CommonCrypto/CommonDigest.h
@interface Utilities : NSObject {

}

//generates md5 hash from a string
+ (NSString *) returnMD5Hash:(NSString*)concat;

@end
##############################################################
in .m





#import "Utilities.h"
@implementation Utilities

//generate md5 hash from string
+ (NSString *) returnMD5Hash:(NSString*)concat {
const char *concat_str = [concat UTF8String];
unsigned char result[CC_MD5_DIGEST_LENGTH];
CC_MD5(concat_str, strlen(concat_str), result);
NSMutableString *hash = [NSMutableString string];
for (int i = 0; i < 16; i++)
[hash appendFormat:@"%02X", result[i]];
return [hash lowercaseString];

}

@end










#######################

in the main Class





NSString *myMD5String = [Utilities returnMD5Hash:@"test"];
NSLog(@" myMD5String ----------------------- %@",myMD5String);




And Its Done , Happy Coding :)
