Encryption & Decryption
Encrypt and decrypt text using various algorithms
Remember this key - you'll need it to decrypt
About Algorithms
- AES: Industry standard, 128-bit block cipher. Best for most use cases.
- Triple DES: Legacy algorithm, applies DES three times. Slower but compatible.
- Rabbit: Fast stream cipher, good for high-speed encryption.
- RC4: Simple stream cipher. Not recommended for sensitive data.
- Base64: Encoding (not encryption). No key needed. Easily reversible.
Security Notes
- All processing happens in your browser
- No data is ever sent to any server
- Use a strong, unique passphrase
- Base64 is NOT encryption - anyone can decode it
- If you lose your key, encrypted data cannot be recovered
