Keeping information safe became a vital necessity in everyday life of any computer user. Our modern world is linked, networked and community-oriented. Your computer at home or at work is connected to the global web. Your information can be accessed by intruder, hacker or even accidental visitor. The best practice for keeping your information is encrypting of any valuable data.

Technological background

Nowadays, symmetric cryptographic algorithms proved to be extremely strong. Such algorithms like Rijndael, CAST, 3-DES and other AES candidates demonstrate no vulnerability, when using them with maximum possible length of the cryptographic key.
However, there is a weak link – a user, who needs to provide initial key for encryption. This key cannot be long and strong enough, since the user has to remember it.
Another minor weakness lies in the core of symmetric algorithm. The same key is used for both encryption and decryption.

How it works?

n-Crypt gives an answer and protection for both vulnerabilities. First, user does not need to provide an initial key, it is generated automatically. A user does not need to remember it. Therefore its length and complexity are absolute for the offered algorithm. The second protection solution is provided by two-layered encryption. File is encrypted by symmetric algorithm with a key generated by the n-Crypt. The key in turn is encrypted using asymmetric RSA algorithm with a public key from the RSA-2048 key pair. When decryption is necessary, the key is first decrypted by a private key of the pair and then it is provided to symmetric algorithm for decryption of the file.

This double-layered protection is ultimate and unbreakable. File that is encrypted using this technology cannot be hacked.

The third layer of offered protection is a recursive encryption technology, where every file in the folder is encrypted with its own randomly generated key. Even when user closes and saves encrypted file after editing, it is encrypted with a new key every time.

It is extremely important that these complicated procedures are absolutely transparent for user. All he needs to do is to Right-Click on the file or folder in the Windows Explorer, to select n-Crypt -> Encrypt.
When user needs to work with encrypted file, he even does not need to decrypt it. Double-click on the file will open it with default application, associated with this file type.

Advantages and Benefits

• Absolute transparency and ease of use
• Two-layered protection
• Military-grade encryption
• Absolute portability - Files may be decrypted by owner with the same biometric device on any computer
