Need to protect your private files on your device? Want to prevent personal photos and videos from being accidentally accessed by friends, coworkers or family members? Have too many usernames, passwords, and credit card numbers to remember thus need a single utility to manage all of them? Here is the solution.
The Secret Locker utility allows you to specify one single password to protect all your secrets. The chosen password is cryptographically hashed then salted using the industry class encryption algorithm to generate a non-reversible key for further encrypting your files.
Not simply hiding the files by moving them around to another folder or changing file names as many other applications do, encrypted files managed by this utility have three levels of protection:
1. Non-root users of your Android device cannot access the repository of this utility
2. Files are encrypted using strong encryption algorithms
3. The password is cryptographically hashed and salted to make it almost impossible to be cracked
Please note the encrypted password itself is locally stored in the application's database. Encrypted files are stored in its own repository on the device as well. No private information is transferred across the Internet. The Internet access permission is only used for the Mobile Ads displayed with this free software.
With the new feature of Google In-app Billing integration, you can upgrade to the Pro version within the application. In this way, you don't need to install another "Secret File Locker Pro" application then migrate files and configurations again.
