Browse GlossaryAES-256
Advanced Encryption Standard with a 256-bit key length. It's the gold standard for encryption, used by governments and security experts worldwide. AES-256 is virtually unbreakable with current technology, making it ideal for protecting sensitive data.
ChaCha20
A modern stream cipher designed as an alternative to AES. It's used by WireGuard VPN protocol and offers excellent performance on devices without hardware AES acceleration, like many mobile devices.
End-to-End Encryption
A security method where data is encrypted on the sender's device and only decrypted on the recipient's device. No one in between—not even service providers—can read the content. Used by messaging apps like Signal and WhatsApp.
Encryption
The process of converting readable data (plaintext) into an unreadable format (ciphertext) using a cryptographic algorithm and key. Only someone with the correct key can decrypt and read the data. Essential for VPNs and secure communications.
Public Key Cryptography
An encryption system using two mathematically linked keys: a public key for encrypting data and a private key for decrypting it. This allows secure communication without needing to share secret keys in advance.
Phishing
A cyberattack where criminals impersonate legitimate organizations via email, text, or fake websites to trick victims into revealing sensitive information like passwords, credit card numbers, or personal data. One of the most common cyber threats.
