MD5 Encryption for Secure Transfer of Password

This blog describes how to encrypt your data using MD5 encryption algorithm.

in .h file

- (NSString *) md5:(NSString *)str;

in your .m file import
#import <CommonCrypto/CommonDigest.h>

Write this method in your .m file:-


- (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]
];
}

Now where ever you want to get an encrypted string do

NSString *md5String=[self md5:@"test"];
NSLog(@"md5String%@",md5String);

On console you will got md5String098f6bcd4621d373cade4e832627b4f6
