No Labels or Markers

The software doesn't write any markers to the container file without the user's permission.

Markers help to identify the file format based on its contents.

No marker available means no one is able to prove (without the password) that the container is a Cryptic Disk one - that it contains encrypted data. The file contents look like a random set of data.

Expandable File Size

Don't know the exact size for your encrypted container? No problem!

Use the "Expandable file size" option. The software adjusts the container file size as you add data to it.

How It Works

Cryptic Disk has a wizard for creating encrypted containers. You set the path for the new container file, its size and the password. There are a lot of other parameters you can set, such as encryption algorithms and file system.
Cryptic Disk can provide access to an encrypted virtual drive stored in the container file. You will need to set a password for this. The software will create a corresponding virtual drive that can be accessed via Explorer or any other file manager.
The virtual encrypted drive in the container you have just created is empty. You can copy or move files to it, and the Cryptic Disk driver will automatically encrypt them before writing to the drive. They are also automatically decrypted upon reading.
So working with an encrypted container is no different from working with a normal drive. Any other software is unable to detect that it is working with an encrypted drive. The drive looks exactly like any other.
