A central encryption and storage manager is provided for securely storing sensitive data values for requestors such as clients. A requester sends an actual data value to the central encryption and storage manager via a secure network connection for storage. After authenticating the requester, the central encryption and storage manager obtains a replacement value associated with the actual data value and encrypts the actual data value. The replacement value and the encrypted actual data value are then stored by the central encryption and storage manager, and the replacement value is transmitted back to the requestor for storage by the requestor. When the requestor needs an actual data value, the requester retrieves the replacement value associated with the actual data value and securely transmits the replacement value to the central encryption and storage manager. After authenticating the requestor, the central encryption and storage manager retrieves the encrypted actual data value using the replacement value, decrypts the actual value, and securely transmits the actual data value back to the requestor.
