Hello @Mummana, Venkatesh Babu ,

Thanks for the question and using MS Q&A platform.

Currently there is no direct functionality in Azure for PGP encryption/Decryption of files. But you can follow any of the below approaches.

1. Using Azure Data Factory: You can write command shells as described in this article and execute them in Databrics notebook activity in ADF. For more detailed information please refer to this article by a community volunteer: PGP File Decrypt Using Azure Data Factory

Below is the sample command for decryption:

gpg --no-tty --batch --import /dbfs/mnt/datalake/configuration/config_decrypt/privatekey.asc  
mkdir -p /dbfs/mnt/datalake/<Output directory>  
gpg --no-tty --batch --yes --ignore-mdc-error --pinentry-mode=loopback --passphrase-fd 1 --passphrase-file /dbfs/mnt/datalake/configuration/config_decrypt/Passphrase.txt --output /dbfs/mnt/datalake/<Output directory>/${output_decrypted_filename} --decrypt /dbfs/mnt/datalake/<Input Directory>/${input_encrypted_filename}  

1. Using Logic Apps/ADF: You can write your own code for encryption/decryption, and execute it in Azure function within ADF using Azure function activity or call that code in Azure functions within Logic apps, or as described in the conversation: What is best way to do PGP file encryption/decryption in logic apps

Hope this will help. Please let us know if any further queries.
