Spare parachute for encrypted data

Create encrypted file vaults with support of multiple keys

– Strong encryption algorithms ensure security of stored information.
– Variable number of file vaults inside single encrypted unit with different key for each vault.
– No possibility of finding the number of file vaults or evidence of their existence.

How does it work?

To encrypt and hide files and folders you should add them to Space (vault) that will be encrypted with a password or a key file.

The key feature is that you can create any number of Spaces inside single encrypted container. Sakhar processor then combines all data from all Spaces, encrypts it, adds disposable data and eventually scrambles resulting container in such a way that it becomes indistinguishable from random data.

After encryption there is no way to find out the number of Spaces or the fact of their existence. You can safely disclose security credentials for multiple Spaces, while keeping the most valuable of them in secret.

The only way to get all the encrypted data is to have all the security credentials used to create the container.

Options & Hints

Noise level

Sets the amount of decoy data that will be injected into resulting container. In general higher levels are more secure, however the size of resulting container may increase significantly.

When encrypting small files it is strongly recommended to set this value at least to 7. If you encrypt multiple Spaces with huge number of files you can set this value to 0 relatively safely.

Number of Cores

Defines the number of simultaneous execution threads used for data encryption or decoding. Defaults to the half of available processor cores.

If you plan to encrypt large files and your system is not under heavy load higher values are recommended.
