About RC4 Encryption
RC4 is a stream cipher known for its simplicity and speed. Supports both RC4 and RC4Drop modes.
- RC4 uses variable-length keys. Use sufficiently long and complex keys for security
- RC4Drop enhances security by dropping initial bytes. Recommend dropping 768 bytes or more
- Ensure using the same key and configuration parameters for encryption and decryption
- For security reasons, RC4 is not recommended for high-security scenarios
