This online tool helps you encrypt text or a file from local storage or a URL using RC4. It supports various modes and padding schemes. It also supports PBKDF2 or EvpKDF, with customizable salt, iteration, and hash settings. It also supports drop bytes.
RC4 is a stream cipher that XORs keystream with plaintext. Decrypt using RC4 decryption.
RC4 has known biases and is deprecated in TLS. Prefer AES-CTR or other modern ciphers.
Dropping initial bytes reduces keystream bias. Set the drop option appropriately in the RC4 tool.
Use PBKDF2/EvpKDF with salt and iterations from a passphrase. You can hash with SHA256.
No. You must know the key (and drop setting) to decrypt. See RC4 decryption.
