Encrypt text with the Rabbit stream cipher instantly using a passphrase.
Use this Rabbit Encrypt tool to encrypt plain text with the Rabbit stream cipher and return Base64 ciphertext. It is useful for browser-side crypto demos, legacy CryptoJS-compatible workflows, reversible testing, and understanding how passphrase-based stream ciphers transform readable input into encrypted output.

Fix: Put the passphrase on the first line and the plaintext below it.
Fix: Rabbit decryption requires the exact same passphrase.
Fix: This tool is better suited for compatibility, demos, and experiments.
Fix: Passphrase first, plaintext below.
Fix: This tool returns Base64 ciphertext for easy copy and reuse.
It encrypts text with the Rabbit stream cipher and returns Base64 ciphertext.
Put the passphrase on the first line and the plaintext below it.
It returns Base64 ciphertext.
No. Rabbit is a stream cipher, while AES is a block cipher.
The reverse tool is Rabbit Decrypt.
