Is it safe to use proxies?

Question

I am using the php curl proxy function to enter the site. I want to know if it is safe or not. Can a proxy site hack my username and password? In fact, I can’t encrypt my password before sending it to the proxy server.

EDIT: The scenario is as follows: I am trying to clear data from just one page. First I log in with my username and password, and then delete the data. I want to do this with a proxy server.

thanks for ur suggestions

Answer 1

Sending a username and password to plain text will never be safe, whether you use a proxy server or not. Yes, the proxy server can read it, and so it can be someone else between you and the site to which you send it.

Answer 2

It is not safe. If you do not trust the proxy, you should not use it to transfer login information. It is absolutely possible to eavesdrop on your password, especially when it is unencrypted.
