In VB6 I require an alogorithm to use in a project to provide licensing feature.
There will be 2 separate projects
The generator will have the following controls
2 Labels = 1) Product Key 2) Activation Key
2 Textboxes = 1) Product Key 2) Activation Key
3 Locked Textboxes = 1) Harddisk Seriak No 2) MAC Address 3) Valid_Days
1 Command Button = Generate
How the generator should work.
- The 3 Locked Textboxes fetches 1)The HardDisk Serial Number 2) The MAC Address 3) Any Number of Days Specified by the [login to view URL] this Test use 2DAYS.
- When the user clicks on the Generate Command Button, 2 different codes of not more than 16 xters should be generated.
The ProductCode is never Stored on the System but the Activation code should be Stored either in an access DB or a binary file. The Activation Code should change at the end of the Valid_Days specified by the Dev.
The Validator will have the following controls
1 Text boxes = 1) ProductCode
1 Listview = 1) List All the Past Activation Keys with their Validity Days
3 Labels = 1) HardDisk S/N 2) MAC Address 3) Valid_Days (Current)
1 Command Button = Decrypt
How the Validator should Work.
The User pastes the ProductCode of any given system generated by the generator from any given system and clicks on the Decrypt command button. The Validator will reveal the 1) Past Activation Codes with their Valid Days on the ListView 2) HardDisk S/N 3) MAC Address 4) Valid_Days (Current Valid_Days Running)
