I am trying to use HMAC 256 algorithm to encrypt my data using HMAC Key. It requires to use GlideCertificateEncryption API and its function generateMac() function to generate encrypted string. But it looks API doesn't support in scoped app. Please let me know how to make it work or is there any API to work in scoped App.

Thanks.
