the AWS `PlainText` hexBinary value into the input field. +- Set the operation input mode to `Hex` and output mode to `Hex`. +- Paste the key into the key argument using the correct format selector. +- Match the AWS algorithm and mode manually in the chosen CyberChef operation. + +Notes: +- AWS documents `EncryptData` as supporting symmetric `TDES` and `AES`, asymmetric `RSA`, and derived `DUKPT` or `EMV` schemes. +- This starter directly covers only the non-derived AES, TDES, and RSA cases. + +## 2) AWS `DecryptData`: AES / TDES / RSA +Operations: +- `AES Decrypt` or `Triple DES Decrypt` or `RSA Decrypt` + +Suggested use: +- Paste the AWS `CipherText` hexBinary value into the input field. +- Set the operation input mode to `Hex` and output mode to `Hex` or `Raw`. +- Paste the key into the key argument using the correct format selector. +- Match the AWS algorithm and mode manually in the chosen CyberChef operation. + +## 3) AWS `ReEncryptData`: Symmetric Rewrap +Operations: +- `AES Decrypt` or `Triple DES Decrypt` +- `AES Encrypt` or `Triple DES Encrypt` + +Suggested use: +- Paste the incoming ciphertext into the input field as hex. +- First decrypt with the incoming key and mode. +- Then encrypt with the outgoing key and mode. + +Notes: +- This covers the software-visible decrypt-then-encrypt pattern. +- It does not model AWS wrapped-key handling or HSM-side key custody. + +## 4) AWS `GenerateMac`: HMAC +Operations: +- `From Hex` +- `HMAC` +- `Take bytes` + +Suggested use: +- Paste the AWS `MessageData` hexBinary value into the input field. +- Run `From Hex`. +- Run `HMAC` with the appropriate key and hash function. +- If AWS truncates the MAC, use `Take bytes` to keep the leftmost bytes that match `MacLength`. + +## 5) AWS `GenerateMac`: CMAC +Operations: +- `From Hex` +- `CMAC` +- `Take bytes` + +Suggested use: +- Paste the AWS `MessageData` hexBinary value into the input field. +- Run `From Hex`. +- Run `CMAC` with `Encryption algorithm` set to `AES` or `Triple DES`. +- Use `Take bytes` to match the requested `MacLength` if truncation is required. + +## 6) AWS `VerifyMac`: Recompute And Compare +Operations: +- `From Hex` +- `HMAC` or `CMAC` +- `Take bytes` + +Suggested use: +- Recompute the MAC using the same starter as `GenerateMac`. +- Compare the result to the AWS `Mac` value manually or with a follow-on comparison recipe. + +## 7) AWS `GenerateCardValidationData`: CVV / CVV2 / iCVV +Operations: +- `Generate card validation data` + +Suggested use: +- Paste the clear combined CVK pair into the input field as hex. +- Choose the profile that matches the AWS card-validation mode you want to emulate. +- Provide the PAN, expiry, and service-code context in the argument fields. + +Notes: +- This directly covers software generation of CVV/CVV2/iCVV-style values. +- Assumption: CVV2 forces service code `000` and iCVV forces `999`. + +## 8) AWS `VerifyCardValidationData`: CVV / CVV2 / iCVV +Operations: +- `Verify card validation data` + +Suggested use: +- Use the same card context as generation, then supply the incoming value in the `Expected value` argument. +- The operation recomputes the value and returns structured verification output. + +Notes: +- This is intended for software parity and regression checks. +- It does not emulate AWS key custody or HSM-side audit semantics. + +## Partial Recipe Starters + +## 9) AWS `EncryptData` / `DecryptData`: DUKPT-Derived Symmetric Flows +Operations: +- `Derive DUKPT key` +- `AES Encrypt` or `AES Decrypt` or `Triple DES Encrypt` or `Triple DES Decrypt` + +Suggested use: +- Derive the transaction key from BDK and KSN first. +- Feed the derived key into the cipher operation that matches your target algorithm. + +Notes: +- This is useful for offline vector work. +- It does not claim one-to-one parity with every AWS DUKPT encryption attribute combination. + +## 10) AWS `GenerateMac` / `VerifyMac`: DUKPT MAC +Operations: +- `Derive DUKPT key` +- `From Hex` +- `CMAC` or `HMAC` +- `Take bytes` + +Suggested use: +- Derive the transaction key from BDK and KSN. +- Convert `MessageData` from hex and generate the MAC using the derived key. + +Notes: +- Treat this as a lab starter, not proof of parity with AWS’s full DUKPT MAC union attributes. + +## 11) AWS `VerifyAuthRequestCryptogram`: EMV ARQC Check +Operations: +- `Generate EMV ARQC` + +Suggested use: +- Paste the already-assembled EMV authorization-request preimage into the input field as hex. +- Provide the already-derived AES session key and cryptogram length. +- Compare the result to the incoming ARQC. + +Notes: +- This is only practical when the session key and exact preimage assembly are already known. +- It is a good fit for AES-CMAC-based profiles, not a full generic EMV verifier. + +## 12) AWS `TranslateKeyMaterial`: ECDH And Wrapped-Key Inspection +Operations: +- `Derive ECDH key material` +- `Parse TR-31 key block` +- `Parse TR-34 B9 envelope` + +Suggested use: +- Use `Derive ECDH key material` to reproduce the shared-secret or KDF stage. +- Use the TR-31 or TR-34 parsers to inspect the wrapped key containers involved in the exchange. + +Notes: +- This helps with interoperability debugging. +- It does not recreate AWS’s HSM-side translate-and-rewrap behavior. + +## 13) AWS `GenerateMac`: EMV MAC Preimage Review +Operations: +- `From Hex` +- `CMAC` +- `Take bytes` + +Suggested use: +- Use this to validate assembled EMV message blocks and truncation behavior when you already know the scheme profile and session key. + +Notes: +- AWS documents `GenerateMac` as supporting EMV MAC. +- This fork does not yet have a dedicated EMV MAC operation, so this remains a profile-specific starter rather than a generic implementation. + +## 14) AWS `GeneratePinData`: Clear PIN Block Build +Operations: +- `Build PIN block` + +Suggested use: +- Paste the clear PIN into the input field. +- Choose ISO format 0, 1, or 3. +- Provide the PAN when the selected format requires it. + +Notes: +- This is useful for software test harnesses that need deterministic clear PIN-block construction before encryption. +- It does not yet implement PVV generation, IBM 3624 offsets, or encrypted AWS response semantics. + +## 15) AWS `TranslatePinData`: Clear PIN Block Translation +Operations: +- `Translate PIN block` + +Suggested use: +- Paste the source clear PIN block into the input field as hex. +- Choose the source and target formats. +- Provide source and target PAN values where required. + +Notes: +- This is a software emulation helper for test-vector work. +- It does not yet emulate encrypted HSM-bound translation between PEK, BDK, or ECDH-derived keys. + +## 16) AWS `VerifyPinData`: Clear PIN Block Inspection +Operations: +- `Parse PIN block` + +Suggested use: +- Paste the clear PIN block into the input field as hex. +- Decode the PIN-block structure and compare the recovered PIN to your expected test data. + +Notes: +- This is only structural verification today. +- It does not yet implement VISA PVV or IBM 3624 verification logic. + +## Not Yet Implemented + +These AWS operations are still valid emulation targets, but do not yet have recipe-equivalent support in this fork: +- `GenerateMacEmvPinChange` +- `GenerateAs2805KekValidation` + +Why: +- They depend on PVV/IBM3624/issuer-script/AS2805-specific payment primitives that are not implemented here. + +## Good Next Additions + +If you want closer AWS coverage, the highest-value missing operations are: +1. PIN block encode/decode for ISO 9564 formats 0, 1, 3, and 4. +2. IBM 3624 and VISA PVV generation and verification. +3. Dedicated EMV MAC and profile-specific EMV session-derivation helpers. +4.

-## 5) AWS `ReEncryptData`: Symmetric Rewrap -Operations: -- `AES Decrypt` or `Triple DES Decrypt` -- `AES Encrypt` or `Triple DES Encrypt` - -Suggested use: -- Paste the incoming ciphertext into the input field as hex. -- First decrypt with the incoming key and mode. -- Then encrypt with the outgoing key and mode. - -Notes: -- This covers the software-visible decrypt-then-encrypt pattern. -- It does not model AWS wrapped-key handling or HSM-side key custody. - -## 6) AWS `ReEncryptData`: Payment Wrapper -Operations: -- `Re-encrypt payment data` - -Suggested use: -- Paste source ciphertext into the input field as hex. -- Define the source decrypt profile and the target encrypt profile in one operation. -- Use this as the payment-facing version of the decrypt-then-encrypt recipe chain. - -## 7) AWS `GenerateMac`: HMAC -Operations: -- `From Hex` -- `HMAC` -- `Take bytes` - -Suggested use: -- Paste the AWS `MessageData` hexBinary value into the input field. -- Run `From Hex`. -- Run `HMAC` with the appropriate key and hash function. -- If AWS truncates the MAC, use `Take bytes` to keep the leftmost bytes that match `MacLength`. - -## 8) AWS `GenerateMac`: CMAC -Operations: -- `From Hex` -- `CMAC` -- `Take bytes` - -Suggested use: -- Paste the AWS `MessageData` hexBinary value into the input field. -- Run `From Hex`. -- Run `CMAC` with `Encryption algorithm` set to `AES` or `Triple DES`. -- Use `Take bytes` to match the requested `MacLength` if truncation is required. - -## 9) AWS `VerifyMac`: Recompute And Compare -Operations: -- `Verify payment MAC` - -Suggested use: -- Paste the message into the input field, choose the MAC method, and provide either the direct key or the DUKPT BDK plus KSN. -- Supply the expected MAC in hex and let the wrapper recompute and compare it. - -Notes: -- This covers the implemented static-key HMAC/CMAC and DUKPT-CMAC wrapper modes directly. -- ISO 9797, EMV MAC, and AS2805-specific verification are still partial gaps. - -## 10) AWS `GenerateMac`: Payment Wrapper -Operations: -- `Generate payment MAC` - -Suggested use: -- Paste the message into the input field and choose the payment MAC method that best matches the AWS attributes. -- Use direct key input for static HMAC or CMAC modes, or provide a BDK plus KSN for the implemented DUKPT CMAC request and response modes. - -Notes: -- This wrapper exists for usability so payment users can stay in the `Payments` category without needing to know which low-level primitive is underneath. -- It intentionally reuses the existing generic `HMAC` and `CMAC` implementations. - -## 11) AWS `GenerateCardValidationData`: CVV / CVV2 / iCVV -Operations: -- `Generate card validation data` - -Suggested use: -- Paste the clear combined CVK pair into the input field as hex. -- Choose the profile that matches the AWS card-validation mode you want to emulate. -- Provide the PAN, expiry, and service-code context in the argument fields. - -Notes: -- This directly covers software generation of CVV/CVV2/iCVV-style values. -- Assumption: CVV2 forces service code `000` and iCVV forces `999`. - -## 12) AWS `VerifyCardValidationData`: CVV / CVV2 / iCVV -Operations: -- `Verify card validation data` - -Suggested use: -- Use the same card context as generation, then supply the incoming value in the `Expected value` argument. -- The operation recomputes the value and returns structured verification output. -

Rebuild Docker and manually confirm that the updated recipe descriptions are visible. -2. Re-run the payment operation subset tests. -3. Spot-check `Populate test data` on argument-heavy operations to ensure the floating-label fix still holds after the latest UI text changes.

To produce APC-compatible EMV MAC output, use `MAC Generate` with ISO 9797-1 Algorithm 3 and Method 1 explicitly selected. +- **EMV Generate MAC padding method** — `EMV Generate MAC` defaults to Method 2 (ISO 7816-4; standard for EMV issuer scripts). Select Method 1 (zero pad) when the receiving system requires it. Both generate and verify must use the same method. - **DUKPT TDES data encryption variant** — CyberChef follows ANSI X9.24-1 standard (bytes 5 and 13 XOR `0xFF` for the "Data" variant). APC applies a different undocumented internal variant. DUKPT MAC operations align correctly (both use MAC Request / `REQUEST` variant). - **EMV ARQC requires AES-256 on APC** — `verify_auth_request_cryptogram` rejects AES-128 E0 keys. If testing ARQC against APC, an AES-256 E0 master key is required. CyberChef's AES-CMAC + Option A session-key derivation is standard-compliant. - **Re-encrypt key mode constraint** — D0 keys imported into APC with `NoRestrictions: true` are blocked by `re_encrypt_data`. This is an APC API constraint, not a CyberChef limitation.

The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms.

The best validation we can do, and it's a pretty good option if I do say so myself, is known value testing against AWS Payment Cryptograpy and it's Futurex backed HSM fleet.
