I have an Azure Function App for GPG encryption/singing and decryption/verification. This is invoked by Azure Data Factory pipelines to perform GPG operations before subsequent SFTP activities.
For authentication to the Function App (from ADF), I'm currently using Function App keys (or could switch to Function Keys easily enough for finer granularity) and this works well, but should I be using AAD? a.k.a. Easy Auth with the App Service Plan
If so, does anyone have some example Terraform scripts for how to do this. There's quite a few auth settings to configure and I haven't come across a simple tutorial/example for this. I'm almost thinking that using Function App keys is easier and probably good enough. Thoughts?
