About ChaCha20 Cipher
What is ChaCha20?
ChaCha20 is a stream cipher designed by Daniel J. Bernstein. It's known for its high performance and security, especially on systems without dedicated AES hardware acceleration.
Key Features
- • 256-bit key size
- • 96-bit nonce (12 bytes)
- • High performance on all platforms
- • Resistant to timing attacks
Security Notes
Never reuse a key-nonce pair. The nonce should be unique for each encryption operation with the same key. ChaCha20 is considered secure for modern cryptographic applications.
Use Cases
- • High-performance encryption
- • Mobile and IoT devices
- • VPN and secure communications
- • Modern TLS implementations
