SQL Replication Batch File Encryption

Hi 

At the moment when creating a batch file, we have to enter in the publisher username and password, we also do this for subscriptions. Obviously with the introduction of GDPR and general security practices this causes an issue.

Is there a way to encrypt text in the batch files? I have found a way to do this using a plugin via Notepad ++, however, I wanted to know if there is an alternative method?

Thanks,

Mark
