the codebase I'm working on is a few versions behind, and an upgrade is requiring me to upgrade the version of cybersource rest client php (we are utilizing it on a drupal website) that we're using. With that update, I've noticed that GeneratePublicKeyRequest and associated functions are gone (they were removed in version 0.0.39) I have not found how you're supposed to replace that behaviour yet though, and was hoping someone could point me the correct documentation. I've searched through the API Reference website/material and haven't found anything that clicks yet. Any help is greatly appreciated!
