Hi guys, a client of mine got this:

- End of Support for RSA PKCSv1.5 Scheme for OAuth 2.0 -
You are receiving this notification because you are still using the RSA PKCSv1.5 scheme in your algorithm for token signing for the OAuth 2.0 client credentials flow. It is still possible to use this scheme until March 1, 2025, but you should update your integrations as soon as possible.

- What is Changing -
The support is ending for the RSA PKCSv1.5 scheme in algorithms for token signing for the OAuth 2.0 client credentials flow. As of March 1, 2025, integrations using the RSA PKCSv1.5 scheme will no longer work.

- Required Actions -
Update your integrations to use the RSA-PSS scheme. The length of the RSA key must be 3072 bits, or 4096 bits, or use an EC key instead. The length of the EC key must be 256 bits, 384 bits, or 521 bits.

If you use any integrations provided by a third party, inform the third party to update the integrations to use the RSSA-PSS scheme, or the EC key.
For more information and examples, see OAuth 2.0 Client Credentials Setup, SuiteAnswers ID 101101.

Anyone here ported to this version and has some key generation code sample to share? i'll be great if you can help me. thanks!

I'm on a Mac and use

openssl req -x509 -newkey rsa:4096 -sha256 -keyout ./private.pem -out ./public.pem -nodes -days 730
