Extension Development Doubt

[ramya]

Hi Admin,

   Please help me out in understanding the code below and develop new extension required for me.
This i found it it 2checkout extension controller page.
what is the use of this? can i modify it and use as checksum validation send by a payment gateway?

// hash check
      if (!md5($this->request->post['sale_id'] . $this->config->get('ccavenue_account') . $this->request->post['invoice_id'] . $this->config->get('ccavenue_secret')) == strtolower($this->request->post['md5_hash'])) {
         exit;
      }

as i understood correctly it's a check of request from 3d party API.. they send md5 hash and extension's controller treid to generate it's own md5 hash which based on it's credentials(invoice_id, sale id etc)...
