Secure iFrame URL Retrieval To securely retrieve the iFrame URL, follow these steps for each request:

Generate RSA Key Pair For every request, a **new **RSA key pair (4096-bit) must be generated. YOU CANNOT USE TWICE THE SAME KEYS !!!

Send the Public Key The public key must be Base64-encoded and sent as a request parameter. Use https://www.base64encode.org/ to test your encode.

Decrypt the Response Decrypt the response using your private key with the following RSA cipher configuration: RSA/NONE/OAEPWithSHA1AndMGF1Padding

For testing or verification purposes, you can use the following RSA tool: https://8gwifi.org/RSAFunctionality?keysize=4096
