L0phtCrack is the original commercial password auditor. Now in our 19th year!
Minor revision updates and bug fixes are included with annual maintenance. Major version updates (e.g., moving from LC6 to LC7, or from LC7 to LC8) require the purchase of a new license.LC7 customers who are current on their annual maintenance will be elegible to purchase LC8 at a discounted rate. Microsoft has a history of making changes at the OS level which break security tool functionality. If this happens, we will update LC to add compatibility when possible.
Your LC7 license includes 1 year of support and updates. To continue to receive support and updates after the initial 1-year period, you must pay an annual maintenance fee.
