Hi @Ruby0911 ,
Welcome to Microsoft Q&A platform and thanks for using this forum.
Unfortunately there is no out of box feature in Azure Data factory to perform encryption/decryption of files. Below are couple of feature request suggestions submitted by other Azure users. Please feel free to comment and/or up-vote the user voice items to increase the priority of feature implementation.
As @John Aherne , called out, to move data to/from a data store that Data Factory does not support, or to transform/process data in a way that isn't supported by Data Factory, you can create a Custom activity with your own data movement or transformation logic and use the activity in a pipeline. Or another option you could try out is Azure Function Activity.
