Rabbit Encrypt

Encrypt text with the Rabbit stream cipher instantly using a passphrase.

Tool

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.

About this tool

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.

Use rabbit encrypt when you need a fast browser-based result without extra setup. It works well for quick checks, one-off tasks, and routine formatting or calculation work.

Why use this tool

How to use

  1. Enter the passphrase on the first line
  2. Paste the plaintext below it
  3. Click Run Tool to encrypt the text
  4. Review the Base64 ciphertext output
  5. Use Rabbit Decrypt with the same passphrase to reverse it

Examples

Example

Input

rabbit-key
hello world

Output

Base64 encrypted text

Useful for creating a simple encrypted Rabbit sample.

Example

Input

demo-pass
api_key=12345

Output

Base64 encrypted text

Useful when testing passphrase-based stream encryption on short strings.

Common errors

The user forgets to include a passphrase

Fix: Put the passphrase on the first line and the plaintext below it.

The wrong passphrase is used during decryption

Fix: Rabbit decryption requires the exact same passphrase.

The user expects modern audited encryption guidance

Fix: This tool is better suited for compatibility, demos, and experiments.

The input format is reversed

Fix: Passphrase first, plaintext below.

The user expects hex instead of Base64

Fix: This tool returns Base64 ciphertext for easy copy and reuse.

FAQ

What does Rabbit Encrypt do?

It encrypts text with the Rabbit stream cipher and returns Base64 ciphertext.

How do I enter the passphrase?

Put the passphrase on the first line and the plaintext below it.

What format does the tool return?

It returns Base64 ciphertext.

Is Rabbit the same as AES?

No. Rabbit is a stream cipher, while AES is a block cipher.

What is the reverse of Rabbit Encrypt?

The reverse tool is Rabbit Decrypt.
