SAP Data Serices cryptography

Hey guys. I am working a government POC where i need to "consume" data already encrypted using MS SQL Server "at rest" Always Encrypted feature. I am looking for any references / successful USE CASES where we used SAP Data Services to consume / decrypt MS SQL Server encrypted data. I know we can use a transform to encrypt using AES algorithms and therefore use same key to decrypt in the same transform. I need to know perhaps, how to use external Public Keys? That is what I am wondering..
