What is the Rabbit cipher?

Rabbit is a high-performance stream cipher designed by Martin Boesgaard and colleagues. It uses a 128-bit key and 64-bit IV, produces up to 2^70 bytes before the state repeats, and was a finalist in the eSTREAM cipher competition.

Is Rabbit cipher secure?

Rabbit is considered reasonably secure with no known practical attacks, but it is not as widely vetted as AES or ChaCha20. For critical applications, prefer AES-256-GCM or ChaCha20-Poly1305.

Select the appropriate mode - Encrypt or Decrypt.
The Rabbit stream cipher generates your output instantly in the panel below.

Rabbit Stream Cipher: protect your sensitive data using this fast and efficient encryption algorithm. As a dedicated stream cipher tool, it processes data bit-by-bit (or byte-by-byte) rather than in blocks, making it exceptionally fast for modern web environments. This online encryption tool ensures your messages remain private by performing all operations within your local browser session.

Performance of the Rabbit Encryption Algorithm

The Rabbit cipher is known for its high-speed performance in software, outperforming many traditional block ciphers. It uses a 128-bit key and an internal state that provides high security for various applications. This cryptographic tool is ideal for developers and security enthusiasts who need a reliable way to test or implement Rabbit-based encryption without complex local setups. Use it for secure messaging, data obfuscation, or learning about stream-based cryptography.

Frequently Asked Questions

What does rabbit-cipher do?

rabbit-cipher encrypt and decrypt text with the rabbit stream cipher.

What input does rabbit-cipher accept?

Paste text directly into the input field, or type your data. Most operations handle Unicode, special characters, and multi-line inputs without issue.

How large an input can I process?

There is no hard limit imposed by this tool. Very large inputs (multi-MB text) process within your browser's available memory. For files larger than 50 MB, a command-line tool may be faster.

Can I download the output?

Yes - every output panel includes a Copy to Clipboard button and a Download as file option. Outputs are saved as plain text or the appropriate file format for the operation.
