MD5 Hash a String (such as a password string)

See more Encryption Examples

Demonstrates how to MD5 hash a string to get MD5 hash in hex encoded string representation. (The MD5 hash is 16 bytes, and therefore a hex encoded MD5 hash would be 32 chars.) Objective-C

#import <NSString.h>
#import <CkoCrypt2.h>

NSString *password = @"myPassword";

CkoCrypt2 *crypt = [[CkoCrypt2 alloc] init];
crypt.HashAlgorithm = @"md5";
crypt.EncodingMode = @"hex";
NSString *md5Hex = [crypt HashStringENC: password];
NSLog(@"%@%@",@"MD5 hash (as a hex string) = ",md5Hex);

//  The hex string will be uppercase.  Your application
//  can easily convert it to lowercase if desired via non-Chilkat means..
