Apply CipherSaber2 Encrypt with explicit key, format, and algorithm settings. Enter the data and key material, choose the parameters, then review the result.

This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

CipherSaber2 Encryption uses RC4-based CipherSaber2 encryption to process the supplied input. It prepends the generated IV to encrypted bytes. Repeating the same input can produce different output.

It prepends the generated IV to encrypted bytes. Repeating the same input can produce different output. Processing runs in the browser for this catalog category, so the result depends on the supplied bytes and settings. Processing runs in the browser.

This tool performs the selected algorithm locally; it does not provide application trust or key management.

Instructions

  1. Provide text or data for this tool.
  2. Keep the first 10 output bytes with the ciphertext. This applies to CipherSaber2 Encryption.
  3. Pass the complete byte result to CipherSaber2 Decrypt with the same key and rounds. This applies to CipherSaber2 Encryption.

Example

Input: Use bytes for "abc", Key "public-test" in UTF8, and Rounds 20.

Settings: CipherSaber2 Encryption: Rounds controls repeated key scheduling, not a block-cipher mode. The operation creates a random 10-byte IV automatically.

Result: It prepends the generated IV to encrypted bytes. Repeating the same input can produce different output. Processing runs in the browser for this catalog category, so the result depends on the supplied bytes and settings.

Limits

  • CipherSaber2 Encryption: Do not remove the IV prefix when saving output.
  • CipherSaber2 Encryption: This legacy RC4 construction does not authenticate the ciphertext.

Questions

Which CipherSaber2 settings must match?

Use the same Key and Rounds as the matching operation. CipherSaber2 has its own ciphertext framing around an RC4-based transformation. Raw RC4 output is not automatically a CipherSaber2 message.

Why does CipherSaber2 return binary data?

The operation consumes or produces bytes rather than a printable encoding. Preserve the complete byte sequence when transferring between operations. Copying an altered text rendering can prevent a correct round trip.

Is CipherSaber2 a password recovery tool?

No. It uses the supplied key rather than discovering an unknown key. Its historical RC4-based design and a completed operation do not establish modern message authentication.
