The default is an EMV standard list of ARQC message tags. The host may also customize the contents of ARQC messages by setting Property 1.1.1.1.1.2 EMV ARQC Message Tag List. ## EMV ARQC (DynaPro Format) Type ## Table ARQC-1 - EMV ARQC (DynaPro Format) Type

## Table ARQC-3 - EMV ARQC (DynaPro Format) Type


Tag	Len	Value / Description	Typ	Req	Default
Padding to ensure the length of data, starting with the message length at the very beginning, and ending with any additional padding, is a multiple of 8 bytes for TDES, or 16 bytes for AES. This is a requirement of using the CBC-MAC algorithm.
Four-byte CBC-MAC. The host should calculate the CBC-MAC and verify that it matches. For details about calculating a CBC-MAC, see About Message Authentication Codes (MAC).

The device encrypts the value inside the Encrypted Data Primitive container using the Encrypted Transaction Data Encryption Type parameter and working key associated with the keyset number currently active in the device’s configuration. As a requirement for using DUKPT encryption algorithms, the device pads it so the length of its value is a multiple of 8 bytes for TDES, or 16 bytes for AES. The device uses container DFDF58 to report how many bytes of data object DFDF59 are padding. Data object DFDF59 itself is formatted like Table 20 after the host decrypts it. ## Table ARQC-4 - EMV ARQC (DynaPro Format) DFDF59 Decrypted Contents

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://developer.magtek.com/api-and-command-reference/scra-dynafamily-programmers-manual/data-types-and-shared-tlv-data-objects/emv-arqc-type.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
