Drivers Licence Scanning
Data
The barcode on the back of a South African drivers licence contains 720 bytes encoded into a PDF417 barcode format. The first 4 bytes contains a version number that should be used to decide which of the encryption keys to use. All currently valid licences use version 2 for decryption.
| Version bytes | Version |
|---|---|
01 e1 02 45 |
Version 1 |
01 9b 09 45 |
Version 2 |
Following the version number are 2 bytes containing zeros, i.e. 00 00. The remaining 714 bytes contains the encrypted drivers licence data.
Decryption
The data should be divided into 6 blocks. The first 5 blocks should each be 128 bytes, and the remaining block should be 74 bytes. Each of the licence data blocks should be decrypted using RSA ENCRYPT with the specific licence version public key.
The licence holder details are contained within the first block.

Usage
// Byte array contianing raw licence bytes from barcode
var encryptedLicenceBytes = ...;
// Decrypt and decode licence fields
var driversLicenceService = new DriversLicenceService();
var decryptedLicenceBytes = driversLicenceService.DecryptLicence(encryptedLicenceBytes);
var licence = driversLicenceService.DecodeLicence(decryptedLicenceBytes);
// Read fields from licence object
var surname = licence.Surname;
var initials = licence.Initials;
