+ (NSString*)md5HexDigest:(NSString*)input {
    const char* str = [input UTF8String];
    unsigned char result[CC_MD5_DIGEST_LENGTH];
    CC_MD5(str, strlen(str), result);

    NSMutableString *ret = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH*2];
    for(int i = 0; i<CC_MD5_DIGEST_LENGTH; i++) {
        [ret appendFormat:@"%02x",result[i]];
    }
    return ret;
}

Sometime your NSURL does not make properly by using URLWithString, Why have you created two nsstring NSString *username, *password; .If you are not modifying them then you can use them directly like:-

Try this:-

   NSString *str = @"https://www.example.org/login.php";
   NSURL *url = [NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
   ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
  [request setPostValue:usernameField.text forKey:@"vb_login_username"];
  [request setPostValue:passwordField.text forKey:@"vb_login_password"];
  [request setTimeOutSeconds:120];
  [request setDelegate:self];
  [request startAsynchronous];
  NSLog(@"%@",[request responseString]);
  NSLog(@"%d",[request responseStatusCode]);
