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

Box Cipher for Caesar Processor uses AES to process the supplied input. The operation returns encrypted or decrypted text or bytes in the selected output encoding. This record describes cipher processing for Box Cipher for Caesar Processor.

The operation returns encrypted or decrypted text or bytes in the selected output encoding. This record describes cipher processing for Box Cipher for Caesar Processor. Processing runs in the browser for this catalog category, so the result depends on the supplied bytes and settings. Processing runs in the browser.

AES protects data only when used with a secret key and compatible authenticated settings; it does not prove sender identity.

Instructions

  1. Provide text or data for this tool.
  2. Use public test values only, then select the required AES mode. This applies to Box Cipher for Caesar Processor.
  3. Keep the key, IV, mode, input encoding, and output encoding identical for a round trip. This applies to Box Cipher for Caesar Processor.
  4. For GCM, provide the tag and matching additional authenticated data when decrypting. This applies to Box Cipher for Caesar Processor.

Example

Input: Plaintext "Test message"; key "00112233445566778899aabbccddeeff"; IV "00000000000000000000000000000000". Operation direction: cipher processing; algorithm: Box Cipher for Caesar Processor.

Settings: Box Cipher for Caesar Processor: Key encoding: Hex; key length: 16, 24, or 32 bytes. Mode: CBC, CFB, OFB, CTR, GCM, ECB, or the listed no-padding variant. IV: 16 bytes for non-ECB modes; input and output: Text or Hex.

Result: The operation returns encrypted or decrypted text or bytes in the selected output encoding. This record describes cipher processing for Box Cipher for Caesar Processor. Processing runs in the browser for this catalog category, so the result depends on the supplied bytes and settings.

Limits

  • Box Cipher for Caesar Processor: The operation requires a 16-, 24-, or 32-byte key.
  • Box Cipher for Caesar Processor: CBC, CFB, OFB, CTR, and ECB do not authenticate ciphertext.
  • Box Cipher for Caesar Processor: GCM decryption fails when ciphertext, tag, key, IV, or additional data differs.

Questions

Is Caesar Box the same as a Caesar letter shift?

No. This operation rearranges positions using Box Height rather than shifting alphabet letters. Changing the height changes which positions the operation reads together. A ROT13 or Caesar-shift setting does not substitute for Box Height.

Will Caesar Box preserve spaces?

The operation removes literal spaces before producing the transposed result. It also skips internal null padding when assembling output. Save the original if its spacing carries meaning.

Can Caesar Box identify the correct height?

The tool applies the height you supply rather than searching for a convincing plaintext. Test a small known example and keep the exact source characters. A completed transposition does not confirm that the puzzle uses this scheme.
