Whenever I use a secure proxy with Google Chrome I get ERR_PROXY_CERTIFICATE_INVALID, I tried a lot of different scenarios and versions.

The certificate

I'm using a self-signed certificate:

openssl genrsa -out key.pem 1024
openssl req -new -key key.pem -out request.pem
openssl x509 -req -days 30 -in request.pem -signkey key.pem -out certificate.pem

Note: this certificate works (with a warning since it's self-signed) when I try to setup a simple HTTPS server.

The proxy

Then I start a secure proxy on localhost:8080. There are a several ways to accomplish this, I tried:

• a custom Node.js script;
• stunnel;
• node-spdyproxy (OK, this involves SPDY too, but later... the problem is the same);
• [...]

The browser

Then I run Google Chrome with:

google-chrome --proxy-server=https://localhost:8080 http://superuser.com

to load, say, http://superuser.com.

The issue

All I get is:

Error 136 (net::ERR_PROXY_CERTIFICATE_INVALID): Unknown error.

in the window, and something like:

[13633:13639:1017/182333:ERROR:cert_verify_proc_nss.cc(790)] CERT_PKIXVerifyCert for localhost failed err=-8179

in the console.

Note: this is not the big red warning that complains about insecure certificates.

Now, I have to admit that I'm quite n00b for what concerns certificates and such, if I'm missing some fundamental points, please let me know.
