The Cryptboard is a new concept in east-tec InvisibleSecrets. While working in Windows Explorer (or any other shell application) you can add files to the Cryptboard. The Cryptboard keeps the files in a list, and therefore at any time you want, you can make operations to the entire list of files.
To add a file to the Cryptboard using any shell application: right click any files or folders and choose InvisibleSecrets / Add to Cryptboard.
So consider the Cryptboard like a shopping basket where you add files, and the security operation like a "check out".
In the Cryptboard all the east-tec InvisibleSecrets security functions are available: Hide, Encrypt, Decrypt, Shred and SFD Package (Self Decrypting Package). After you filled the cryptboard with several files and folders from any location, you can perform a security operation in a single step.
