I haven't seen the socket error while testing without ProxHTTPSProxy.
I did, however, just experience a long stall while signing in at yahoo without ProxHTTPSProxy.

So the error may not be a problem.

Accepted and easier. Smile!
My tradition is that readme is a stand-alone text document.

RE: ProxHTTPSProxy, a Proxomitron SSL Helper Program
Third published draft.

Code:
ProxHTTPSProxy creates two local servers, "front" and "rear",
to provide modern secure https connections for the Proxomitron local proxy.

Show ProxHTTPSProxy.png

--------------------------------------------------------------------------------------------------------------------------------------------------------------------

To run ProxHTTPSProxy.py:

Install the latest Python 3.x from  https://www.python.org/download/
Install the latest OpenSSL from     http://www.slproweb.com/products/Win32OpenSSL.html
                                    OpenSSL needs "Visual C++ 2008 Redistributables"
Install pyOpenSSL                   https://pypi.python.org/pypi/pyOpenSSL/0.14
Install urllib3                     https://pypi.python.org/pypi/urllib3
Install colorama                    https://pypi.python.org/pypi/colorama

Use a direct connection while installing these libraries!

Assuming that Python installed to c:\Python34:
c:\Python34\Scripts>pip install pyopenssl
c:\Python34\Scripts>pip install urllib3
c:\Python34\Scripts>pip install colorama

For new Python users:
Window's command-prompt window should eventually resemble cmdexe.png without
the highlighting of the commands that you will enter.

Double-click on ProxHTTPSProxy.py file to start.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------

To use ProxHTTPSProxy proxies:

Add ProxHTTPSProxy's "CA.crt" to the browser's store of trusted certificate authorities.
Set the browser to use the ProxHTTPSProxy front server for secure connections.
    The front server's default address is 127.0.0.1 on port 8079.
Add the ProxHTTPSProxy rear server to the Proxomitron's list of external proxies.
    The default entry is 127.0.0.1:8081 ProxHTTPSProxy
    , http://proxomitron.info/45/help/External%20Proxy%20Dialog.html .
Add
    $OHDR(Tagged:Proxomitron FrontProxy/*)$SETPROXY(127.0.0.1:8081)(^)|
    to the beginning of the entry in Proxomitron's "Bypass URLs that match this expression" field, http://proxomitron.info/45/help/CfgT2.html#foo .
    If the field is empty, add
    $OHDR(Tagged:Proxomitron FrontProxy/*)$SETPROXY(127.0.0.1:8081)(^)

--------------------------------------------------------------------------------------------------------------------------------------------------------------------

Q and A:

Why is the browser complaining?
ProxHTTPSProxy's "CA.crt" must be in the browser's store of trusted certificate authorities.

Can ProxHTTPSProxy use another port?
Modify "ProxHTTPSProxy.ini" and associated settings in the Proxomitron.

Will the ProxHTTPSProxy certificate store be updated?
Download and replace the "cacert.pem" file in ProxHTTPSProxy with one from http://curl.haxx.se/docs/caextract.html .
Consider emptying the certs folder in the ProxHTTPSProxy folder.

How will the Proxomitron know which connections are https?
By testing for the "Tagged" request header, like $OHDR(Tagged:Proxomitron FrontProxy/*) .

How do I view a site that has a bad certificate?
The Proxomitron can still do https and it may not care. Try a header filter, like

[HTTP headers]
In = FALSE
Out = TRUE
Key = "Tagged: Use Proxomitron for https://badcert.com"
URL = "badcert.com$OHDR(Tagged:Proxomitron FrontProxy/*)$USEPROXY(false)$RDIR(https://badcert.com)"

, after adding the ssl files to the Proxomitron, http://proxomitron.info/files/index.html .
This filter also removes the "Tagged" header.

Redirects of "Tagged" connections, $RDIR(http://local.ptron/killed.gif), don't work?
Use an expression like $USEPROXY(false)$RDIR(http://local.ptron/killed.gif).
Also, before redirecting "Tagged" connections to external resources consider removing the "Tagged" header.

How does the "Bypass URLs that match this expression" entry work?
The Proxomitron always executes some commands in this field.
Putting the entry there allows the Proxomitron to use the rear server when in Bypass mode.
This undocumented feature brings many possibilities but remember, an actual match triggers bypass of filtering!
$OHDR(Tagged:Proxomitron FrontProxy/*) checks for the header that indicates an https request.
$SETPROXY(127.0.0.1:8081) is executed when found.
(^) expression never matches.

Any additional instructions for the current sidki set?
1. Redirect connections to http resources with an expression like $USEPROXY(false)$SET(keyword=i_proxy:0.)$RDIR(http://local.ptron/killed.gif).
2. Add the following two lines to Exceptions-U
   $OHDR(Tagged:Proxomitron FrontProxy/*)$SET(keyword=$GET(keyword)i_proxy:3.)(^)
   ~(^$TST(keyword=i_proxy:[03].))$OHDR(Tagged:Proxomitron FrontProxy/*)$SET(keyword=$GET(keyword)i_proxy:3.)(^)

Why is this better than using the Proxomitron's ssl routine?
The Proxomitron's ssl routine is dated.
The many alerts from the browser and the Proxomitron may cause some users to disable all alerts.

Why is this better than using half-ssl?
The purpose of half-ssl is to hide the secure connection from the browser.
Half-ssl routines are often an incomplete solution.
The Proxomitron's ssl routine is dated.  
The many alerts may cause some users to disable all alerts.
Cookies and other data may be incorrectly assigned.
Browsers should not treat secure data the same as insecure data.

Should I filter https?
Be aware and careful! But...
So many ordinary everyday sites (yahoo, google, etc) and servers are now using https that you may not have a choice.
However, use a direct connection when you don't want any mistakes made.
Remember, use at your own risk!

Have fun!

RE: ProxHTTPSProxy, a Proxomitron SSL Helper Program
Finally got an exe version working. http://proxfilter.net/ProxHTTPSProxy0.8d.zip 4.5MB.

The only external dependency is OpenSSL, and the "Visual C++ 2008 Redistributables" that OpenSSL needs. You need to restart your computer after OpenSSL installation to make its binary work.

JJoe, thanks for the document work. I will check it later. Time to have a break now.

Consider emptying the certs folder in the ProxHTTPSProxy folder.

This is not needed for updating the "cacert.pem". You only HAVE TO do it after you change the "CA.crt", which is used to sign those site certificates.

Thanks for the clue. Please download again and let me know it works now. The installation part of the doc could be simplified if it works.

Would you advise a new name for this proxy or just keep it as is?

I had not considered that. It is a 10 year cert.
I saw the cache as a possible privacy issue. It will show browsing history.

Glad it worked! CheersApplause

Other proxies are using the first ProxHTTPSProxy.
The two ProxHTTPSProxys have different abilities.
The first ProxHTTPSProxy can use socks, http, and https proxies.
The second can only use https proxies but supports verification.
If both groups of users seek help, one name could be a problem.

I would change it but I don't think it has to be a new name.
I have been using ProxHTTPSProxyMII for the second version.
Also, I have changed __version__ to 0.8dpy, "py" to distinguish it from the new "exe" version.

But, whatever you decide is perfectly ok.
You won't have to use the readme either. Smile!

Do you want to have a "py" and an "exe" package?

For anyone who worries that a site could use that CA to fake https, I added a function that the program will create a new CA if you delete the bundled one.

I will definitely use it, until you think the program is ready to be out of beta. I don't have much time to fully test it and have to count on you.

v0.9 adds bypass function. The python version is attached, and the exe version here: http://proxfilter.net/ProxHTTPSProxyMII0.9.zip .

RE: ProxHTTPSProxy, a Proxomitron SSL Helper Program
The PY version is very good. Thumbs Up

The exe is having problems, however.
After commenting out "yahoo.com" and "yimg.com" in "ProxHTTPSProxy.ini" Wink and emptying certs cache,
yahoo.com eventually loads without some yimg resources. To get more resources, I remove ".yimg.com.crt" from the cert cache and load a missing image to create a new cert.

Sometimes, the cert I remove is missing the Private Key but not always.

ProxHTTPSProxy log window shows:

The exe version uses OpenSSL command line to create certs, and my current routine is not reliable if multiple threads are doing the same thing. So don't empty those certs unless you change the CA. Smile!

RE: ProxHTTPSProxy, a Proxomitron SSL Helper Program
A little more info...

These errors occured while using IE11, visiting site for first time with a clean install of ProxHTTPSProxy 0.9 exe.

Code:
[16:18:22] "GET https://farm6.staticflickr.com/5489/14482714055_1583998180_s.jpg
HTTP/1.1" 200 7415
[16:18:23] [F] [X509: KEY_VALUES_MISMATCH] key values mismatch (_ssl.c:2532) on
connection.
[16:18:24] "GET https://farm6.staticflickr.com/5499/14426902271_b481280526_s.jpg

[16:18:24] [F] [SSL] PEM lib (_ssl.c:2532) on connection.
[16:18:24] [F] [SSL] PEM lib (_ssl.c:2532) on connection.
[16:18:24] [F] [SSL] PEM lib (_ssl.c:2532) on connection.

The images did load after reloading the page, however. These errors have not been seen again.

So, I may be seeing two kinds of errors while using the exe.
1. Incomplete cert generated.
2. Good cert generated but somehow misapplied.
