Hi,<br />
<br />
we are in the process of re-designing our website in such a way where the user is required to enter a CVV2 value. &nbsp;For the PAN (Primary Account Number) there is this algorithm that allows us to check the validity of that number prior to posting that page back to the server and/or to the authorization service. &nbsp;I was wondering if there is algorithm or checksum for the CVV2 values.<br />
<br />
thanks

CVV2 algorithm

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
