To ensure the highest level of data encryption in IntelliVPN service applies symmetric encryption AES-256 (Advanced Encryption Standard 256-bit.) in CBC mode (Cipher block chaining). Symmetric encryption is used with the temporary private key.
To check the integrity of the data, use HMAC (Hash-Based Message Authentication Code) with the hash algorithm SHA-384 (Secure Hash Algorithm 384-bit.). Checking the data integrity is necessary for their protection against active attacks.
To establish a secure connection between the user device and our VPN servers uses a cryptographic algorithm RSA-2048 public key. Exchange temporary keys take place on protocol DH (Diffie-Hellman) Group 14 2048 bits.
