I've started to process about encryption/decryption with mVisa Receive Side API.
Why do shared secret key I got in my project has length of 40 bytes, I expected it's length is 32 bytes corresponding to 256-bit.
This document decribes that it use AESGCM 256, as "The field is sent in encrypted format using the AES GCM (i.e. Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM)) algorithm for JSON Web Encryption (JWE) objects with 256-bit key (i.e. the shared secret between Visa and client for encryption and decryption of payload data)"
Thanks for inquiring about the Visa Direct mVisa API. Before moving forward, it is important to review the Visa Direct documentation via this link - https://developer.visa.com/capabilities/visa_direct/docs
In particular, please see the top few paragraphs that are shaded in yellow that discuss the requirements to use Visa Direct. After having read the documentation, if you meet those requirements, then please click through the link in those paragraphs to the Visa Direct Program Implementation Questionnaire, fill it out, and submit to the email address listed on that form. Please let us know if you have other questions.

Hey there @denial245,
For Visa Direct, it's not required to have the IV for GCM mode. We support only AES – GCM algorithm. IV is not applicable for encryption/decryption as we use the GCM mode in AES.
Thank you for this article. I also wants to add a payment method on my website. Is it possible to add it on showbox official site.
Can you please provide us with your use case so that I can assist you further?

First of all thanks for helping out everyone who is posting queries in this thread.
I am currently working on a project which is distro.fm in which I want to collect money for a charity firm. I have the option of Paypal integration in my site, means users can donate money via PayPal but many of them have asked me to integrate Credit card (especially visa) to integrate into the checkout page. So, I have read the agreement and about encryption/decryption with mVisa Receive Side API. My question is that is it totally safe for the user perspective? does my user's data safe if they transact using mVisa? I know that AESGCM 256 encryption is good but still want to confirm from you.
