DusuPay Public Keys

This section shares the two public keys used by DusuPay for the two environments (Sandbox and Production). The keys can be copied and stored as files to later be used in transaction processing.

The DusuPay public key serves two critical purposes as briefly described below.

Purpose	Description
RSA Signature Verification	Callbacks from DusuPay carry a header named rsa-signature and with the public key, the signature can be verified as described here to confirm authenticity.
Card details encryption	When the merchant opts for the direct card payment option, the public key is used to encrypt the card details as described in this section

We recommend that for each environment you're working with, the key content is copied and stored in your workflow based on how you see fit. In this documentation however, we will assume the content is stored in a file named dusupay.public.key.pem and referenced from there for all described usage.
