NetBackups web application uses a combination of Blowfish encryption and SSL secure data transmission to ensure the safety of your data. You connect to our website application using a secure SSL (1024 bit RSA key exchange, 128 bit RCA stream cipher and SHA-1 integrity checking) connection to transfer the data. Signed SSL certificates and Certificate Revocation Lists (CRLs) are used to verify server integrity. Data is stored using 448-bit Blowfish encryption to encode the data on the Server.

This is considerably greater than the encryption used for Internet banking and online credit card transactions.

NetBackups uses a combination of Blowfish encryption and SSL secure data transmission to ensure the safety of your data

Blowfish is an encryption algorithm. It is a symmetric block cipher, which uses a variable-length key from 32 bits to 448 bits. At NetBackups we use the maximum strength 448-bit key

Blowfish is a variable-length key, 64-bit block cipher. The algorithm consists of two parts: a key-expansion part and a data- encryption part. Key expansion converts a key of at most 448 bits into several subkey arrays totalling 4168 bytes.

Data encryption occurs via a 16-round Feistel network. Each round consists of a key-dependent permutation, and a key- and data-dependent substitution. All operations are XORs and additions on 32-bit words. The only additional operations are four indexed array data lookups per round.

Decryption is exactly the same as encryption, except that Parrays are used in the reverse order.

Your data is encrypted the moment it leaves your PC to be stored onto the NetVault. A random encryption key is automatically generated when any account is created and this random key is used to encrypt your files.

Your encryption key is not stored anywhere on the application.

The Secure Sockets Layer (SSL) is a commonly used protocol for managing the security of data transmission. SSL uses the public-and-private key encryption system from RSA, which also includes the use of a digital certificate.

1. Browser checks the certificate to make sure that the site you are connecting to is the real site and not someone intercepting.

2. Determine encryption types that the browser and web site server can both use to understand each other.

3. Browser and Server send each other unique codes to use when scrambling (or encrypting) the information that will be sent.

4. The browser and server start talking using the encryption, the web browser shows the encrypting icon, and web pages are processed securely.
