RC4 Encryption / Decryption

Encrypt or decrypt data using the RC4 stream cipher algorithm

100% Client-Side Processing

All file hashing happens directly in your browser. Files are never uploaded to any server, ensuring complete privacy and security for sensitive data. Our implementation produces hash values that are bit-for-bit identical to those generated by command-line tools.

RC4 accepts variable length keys (typically 5-16 bytes). For security, longer keys are recommended.
