# Decrypt & Forward
**Magensa Decrypt & Forward (DaF)** is a PCI-DSS-certified cloud gateway that acts as a secure "wrapper": it decrypts data captured by a MagTek MagneSafe reader, injects the decrypted card fields into a payload of your choosing, and forwards the request to any third-party endpoint on your behalf — even one with no decryption service of its own. Built on the MagneSafe Security Architecture with L3-certified hardware, TDEA/AES encryption, and DUKPT key management, it handles every major payment type — magstripe, EMV contact and contactless, NFC wallets like Apple Pay and Google Pay, QR codes, gift cards, and more — and is certified with the major US processors, giving ISVs and integrators a single integration point that speeds time to market and shrinks PCI scope. Use the references below to explore the DaF API and related payment operations, grab sample code from GitHub, or open the support hub for manuals, brochures, developer guides, and videos.

## 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/services/magensa/decrypt-and-forward.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.
