The basics: what is VPN encryption and why it matters

VPN encryption protects data in transit by transforming readable data plaintext into ciphertext.
Encryption relies on algorithms ciphers and keys. The longer the key and the stronger the algorithm, the harder it is to decrypt without the key.
Integrity checks and authentication ensure that data hasn’t been tampered with and that you’re talking to the right server.

Key terms you’ll hear a lot

Cipher: the algorithm used to encrypt data e.g., AES-256
Key length: how many bits the encryption key has e.g., 256-bit
Protocol: the method used to negotiate encryption and transport data e.g., OpenVPN, WireGuard
Authentication: verifies who you are and who the other end is certificates, pre-shared keys
Forward secrecy: a property that ensures session keys are not compromised even if the server’s private key is compromised in the future
Handshake: the process where client and server establish secure parameters

Popular VPN encryption algorithms and their characteristics

AES-256-GCM: widely regarded as the gold standard for VPNs. It provides strong confidentiality and built-in integrity.
ChaCha20-Poly1305: fast on devices with limited hardware acceleration, good security, often used in WireGuard.
RSA-2048/4096 and ECDSA: used for key exchange and authenticating servers; modern setups prefer Elliptic Curve variants for smaller keys with similar security.
SHA-2 and SHA-3 families: used for message authentication integrity checks. SHA-256/384/512 are common; SHA-3 is newer.

Key takeaways

Modern VPNs commonly use AES-256-GCM or ChaCha20-Poly1305 for encryption with strong integrity.
The choice of cipher affects performance on devices with limited CPU features; ChaCha20-Poly1305 often performs well on mobile.
Always pair encryption with strong authentication and forward secrecy.
