What Is Encryption?
Encryption is a fundamental security technology that transforms plaintext data into ciphertext using a mathematical algorithm and an encryption key. Only someone with the correct decryption key can reverse the process.
There are two main types: symmetric (same key for encryption/decryption, like AES and ChaCha20) and asymmetric (different keys, like RSA and Curve25519). VPN protocols typically use asymmetric encryption for key exchange and symmetric for data transfer.
Why Encryption Matters for Online Privacy
Without encryption, all data on the internet can be read by anyone with network access. Even HTTPS only encrypts data between browser and website; your ISP can still see which domains you visit. VPN encryption wraps all your traffic in an additional layer of protection.
VPNWG Encryption Standard
VPNWG uses ChaCha20-Poly1305, a 256-bit authenticated encryption algorithm. Combined with Curve25519 key exchange and Perfect Forward Secrecy, VPNWG's encryption is mathematically impossible to crack. Learn about our encryption stack.
