Modern Stream Cipher

INPUT

Plaintext

256-bit Key (Hex)

96-bit Nonce (Hex)

ALGORITHM INFO

Type:Stream Cipher

Key Size:256 bits

Nonce Size:96 bits

Rounds:20

Security:Very High

OUTPUT

Encrypted data will appear here...

Important: Never reuse a nonce with the same key. Each encryption operation should use a unique nonce to maintain security.

What is ChaCha20?

ChaCha20 is a modern stream cipher designed by Daniel J. Bernstein. It is part of the ChaCha family of ciphers and is known for its high performance and security.

Unlike block ciphers like AES, ChaCha20 generates a keystream that is XORed with the plaintext, making it extremely fast in software implementations.

Security & Performance

Resistant to Attacks

Designed to be resistant to cache-timing attacks, which can affect software implementations of AES.

High Efficiency

Performant on a wide range of hardware, including mobile devices and systems without hardware AES acceleration.

Secure & Private

All processing happens locally in your browser. Your keys and sensitive data are never uploaded to any server.

This tool uses a pure JavaScript implementation for educational demonstration.

Always use a unique nonce for every encryption operation with the same key.
