You may have sensitive files stored in your computer that you don't want anyone else to access. The Vault is a good way to protect them from prying eyes.
The Vault creates a virtual safe for your files in your hard drive. You can have as many vaults as you need, each one of them with their own folder structure – just like Windows Explorer. The program supports four encryption algorithms (Blowfish, AES, Serpent and Twofish) and four types of hash functions (MD5 128, Sha 256, Sha 384 and Sha 512).
The Vault doesn't require installation. When you run it for the first time you'll be asked to set a master password – which you should never forget. Then you're ready to start creating vaults, adding folders to them and dragging and dropping any files you want to protect into the program's interface. You also have the option to check the encryption performance of each algorithm and hash combination with a built-in test.
Generally speaking The Vault is a handy application but it may not be easy to understand for those who are not familiar with computer security. The fact that the program doesn't include any documentation doesn't help either.
The Vault lets you create encrypted virtual safes in your hard drive to store and protect sensitive data, though it may not be very intuitive for beginners.
