RC4 Encryption
Encrypt and decrypt text using the RC4 symmetric algorithm
Password Strength: Medium
Encrypted Result
Decrypted Result
⚠️ Security Note
RC4 is no longer recommended for highly secure applications due to known vulnerabilities. Consider using more modern encryption algorithms like AES for sensitive data.
About RC4 Encryption
- RC4 (Rivest Cipher 4) is a stream cipher designed by Ronald Rivest in 1987
- It's a symmetric encryption algorithm, meaning the same key is used for both encryption and decryption
- RC4 is fast and efficient, making it suitable for applications where speed is important
- While once widely used in protocols like SSL/TLS, it has been deprecated due to security weaknesses
- For the best security, always use a strong, random key and consider more modern alternatives
