Can lftp read netrc for sftp-connections

I am trying to create a script to upload some files to a server via SFTP. I can do that manually by opening an interactive lftp-session and providing username and password there. For the script, I would like to - not hardcode credentials in the script (for obvious reasons) - not mention them on the commandline (I want the command in my .bash_history, but of course not the credentials) - have lftp read the credentials from .netrc or something similar I cannot seem to get this working. My current workaround is a wrapper-script that parses the .netrc for the credentials and adds them to a lftp-script which I delete afterwards. This simulates the steps I perform manually, but seems like re-implementing existing functionality poorly. While this works, the question remains: > Can lftp read .netrc for SFTP-connections? If so, are there special syntax-requirements if customs ports are part of the setup? I need to connect to sftp://username:password1@example.com:12322.
