I did this

curl -x https://user:password@your-proxy-ip-addess:12/ http://www.google.com

ps -ef | grep curl
curtine 7859 3321 0 17:32 pts/1 00:00:00 curl -x https://user:password@your-proxy-ip-addess:12/ http://www.google.com

I expected the following

Masked password for proxy password. Like mysql does https://unix.stackexchange.com/questions/78757/securely-feeding-a-program-with-a-password

If you provide the name and password with the dedicated -U or --proxy-user flag then curl will (attempt to) hide it.

I don't think we should clear the entire proxy string just because someone might pass their credentials there. We could consider scrubbing out them from the string, but since we have a working way to do this I don't think we have to.

Yes -U masks just fine. Good to know. Might be worth adding to man page.
