/*
Purpose:
    This sample function demonstrates how to encrypt data which was encrypted using a KMS key.
    This function can be used in conjunction with f_kms_decrypt.

    Note: the test input/output is for illustration and would need to be modified to use data that was encrypted with YOUR kms key.
