Locked File
Protect Important Files is an easy but advanced solution for protecting any file, including EXE, PDF and DOC files. With just one account you can lock an unlimited number of files. Just add the file to your account and then use our simple locking software on your file. Only users with a proper registration code will be able to access your file.

Easy Trial Setup

If you want to let your customers try your product before they buy it's easy: can turn any file into a product demo. You can configure a demo based on uses, days, session length, or a combination of all three. There are also advertising supported and nag-screen demos available. At any time during the demo, or when the demo expires, your customers can visit your purchase page to access the full version.

Automate Registrations

When integrated with your payment processor allows your customers to:
  • Download your product
  • Try the trial
  • Visit your purchase page
  • Pay for your product
  • Unlock the full version
Payment, registration and download are completely automated: you don't have to worry about it at all!

Free Trial

The SoftLocker ListBuilder is absolutely free to try for 1 month. Just download the software to get started right away. Our support department is happy to help you lock your files and integrate with your payment processor, and we provide simple HTML tutorials so that you can have an eCommerce website up and running today.

Low Price

At $14.95 per month is very inexpensive compared to other locking programs that cost upwards of $300-500 for a development kit and don't offer free trials. There is no limit to the number of products you can lock with, so the more products you lock the less costs per product. The free trial is just that: totally free. After one month you can subscribe via paypal or just let your account expire.

No Risk

If you no longer have use for or find a better solution you can cancel your account any time. Your current customers will not be affected at all: they will continue to be able to use their registered copies of the product.

How exactly does it work?

  • You add your product to your SoftLocker account by filling out a form
  • You use our locking software to lock your existing file.
  • All of your product information is embedded into your locked file.
  • You distribute your locked file to your users.
  • They try the trial version and decide to register.
  • They click the register button and are brought to your purchase page.
  • Once payment is received your customer is directed to a special link.
  • There they receive their registration code.
  • They enter it into the software and can now use the full version.
  • You can track their uses or remotely disable the registration code at any time

How is my software protected? Can it be cracked?

There is no such thing as a product that can't be cracked: when you run computer code it is visible to the operating system and can potentially be cracked.

Our intent is find a perfect balance between ease of use and security. is designed to be easy to use for you and your customers but difficult for people that want to crack your product. That way your customers are happy, they can't casually pass your software around to friends or post it on the internet, and it is very difficult for even an experienced hacker to crack your software. For security reasons we don't detail exactly how works, but here are some of the technologies in use that protect your locked file:
  • Morphing database storage
  • Triple-check product tampering detection
  • Trials immediately disable upon tampering
  • 128 bit encryption
  • Checksum verification
  • Copy prevention
  • Online registration verification

One major advantage to over traditional KeyGen based systems is that registration codes are stored in an online database. It is impossible for hackers to create a key generator for your locked files because registration codes are completely random and must be created by the servers.
