Rabbit Encryption and Decryption

📖 Description

1. Why Choose the Rabbit Algorithm?

Among the many symmetric encryption algorithms, Rabbit stands out with its unique design:

• Extreme Speed: In software implementations, Rabbit is typically much faster than AES (especially on older devices without AES-NI hardware acceleration).
• Strong Security: With a 128-bit key length and an internal state of up to 513 bits, it effectively resists various known cryptanalysis attacks.
• Stream Cipher Nature: Unlike block ciphers like AES, Rabbit is a stream cipher. This means it handles variable-length data without cumbersome padding, making the logic simpler and more efficient.
• Standard Endorsement: As a top-tier algorithm in the "software profile" of the eSTREAM project, it is a recognized secure choice in modern cryptography.

2. Core Features Explained

This site's tool not only implements standard Rabbit encryption but also incorporates user-friendly customized features:

A. Flexible Key Mechanism (Password/Key)

• Users can define a 128-bit key (or a text string of any length) as the secret key.
• Supports optional IV (Initialization Vector): By introducing an IV, even the same plaintext and key produce completely different ciphertext each time, greatly enhancing resistance to replay attacks.

B. Automatic Base64 Wrapping

• Since Rabbit encryption produces raw binary byte streams, which cannot be displayed directly on web pages or sent via chat tools.
• This tool automatically converts the encrypted result into Base64 format, making it easy for users to copy, paste, and distribute with one click.

C. Absolute Privacy: Browser-Local Computation

• Local Encryption/Decryption: All Rabbit computation logic is performed entirely in your browser's frontend.
• No Data Traces: Your plaintext and key are never uploaded to any server. Even this site's system cannot access your privacy, offering security equivalent to offline software.

3. Encryption/Decryption Effect Comparison

4. Brief Operation Process

Encryption (Hiding Information):

1. Enter or paste your sensitive text in the "Plaintext" box.
2. Input a complex passphrase in the "Key" box.
3. (Optional) Enter an Initialization Vector (IV).
4. Click "Rabbit Encrypt", and the ciphertext will instantly appear in the result box.

Decryption (Restoring Information):

1. Paste the received Base64 ciphertext.
2. Input the correct key (and IV) provided by the other party.
3. Click "Rabbit Decrypt", and the original text will be perfectly restored.
