Jabber password recovery for Miranda IM users
Yeah, that happens with me too. Finally I forgot my password on jabber :-)
I used Miranda IM instant messenger for Windows.
And when I needed to enter the password in another jabber client on my phone, it turned out that I forgot it.
Search in google gave me some links to programs that allow me to recover forgotten passwords.
However, I do not trust them. There are no guarantees that your password will not be known by third parties.
Luckily I'm a programmer, familiar with network protocols, and so I decided to try to extract the password from Miranda IM myself.
First, I found in Miranda IM settings that allow me to disable encryption (turn off "Use SSL" and "Use TLS").
Also, I can turn of compression (uncheck "Enable stream compression (if possible)" on Advanced tab).
That allowed me to use a sniffer to examine the protocol exchange between Miranda IM and the jabber server.
Second, I found that I can "Manually specify connection host". That allows me to make my own "jabber server" that will interact with my jabber client, run it on my computer and tell Miranda IM use it instead of real jabber server. I named it JabberHost.
Third, I found that the jabber server in its first response informs of possible authentication mechanisms, including PLAIN:
<?xml version='1.0'?><stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' from='jabber.org' id='1647f61c13930926' version='1.0'>
<stream:features><starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>
<mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
<mechanism>CRAM-MD5</mechanism>
<mechanism>LOGIN</mechanism>
<mechanism>PLAIN</mechanism>
<mechanism>DIGEST-MD5</mechanism>
<mechanism>SCRAM-SHA-1</mechanism>
</mechanisms>
<compression xmlns='http://jabber.org/features/compress'><method>zlib</method></compression>
<ver xmlns='urn:xmpp:features:rosterver'>
<optional/></ver></stream:features>
PLAIN authentication is pretty simple. Value of <auth> tag, that jabber client sends to the server is the BASE64-encoded string of this format:
'authid\0userid\0passwd' where '\0' is the null byte.
JabberHost changes the response about available authentication mechanisms, and tells jabber client that it supports only PLAIN authentication:
<?xml version='1.0'?><stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' from='jabber.org' id='1647f61c13930926' version='1.0'>
<stream:features><starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>
<mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
<mechanism>PLAIN</mechanism>
</mechanisms>
<compression xmlns='http://jabber.org/features/compress'><method>zlib</method></compression>
<ver xmlns='urn:xmpp:features:rosterver'>
<optional/></ver></stream:features>
When jabber client sends authentication info to JabberHost, it decodes the user name and password and displays.
You can freely download sources of JabberHost as well as compiled binary file here.
On the picture below I have shown the necessary settings in Miranda IM.

"wpchost.exe has stopped working"
When you run Web Proxy Checker Pro under non-administrative account you may get the error "wpchost.exe has stopped working" (see screenshot below).
That happens because Web Proxy Checker Pro process (wpcp.exe) does not have rights to launch the host process (wpchost.exe).
To avoid this problem you need to change Privilege Level for wpcp.exe - see the screenshot below.

Howto: run several instances of proxy checker
This trick is about running several instances of proxy checker from different locations (folders).
To run 2 instances of Web Proxy Checker you need to create 2 folders for each instance (for ex. C:\WPC1 and C:\WPC2) and copy to these folders 4 files from C:\Program Files\Opt-In Software (I assume that proxy checker was installed to this folder):
wpcp.exe
WPCHost.exe
libeay32.dll
ssleay32.dll
Now you can run 2 instances of proxy checker (wpcp.exe) - first instance from folder C:\WPC1, second instance from folder C:\WPC2.
The problem here is that by default Web Proxy Checker stores application settings to user's Application Data folder. That means that all instances of program will share their settings. To avoid this problem you can use command line argument -appsettingsdir to specify where to save application settings.
To run first instance use this command:
C:\WPC1\wpcp.exe -appsettingsdir
To run second instance use this command:
C:\WPC2\wpcp.exe -appsettingsdir
The same trick works for other Opt-In Software applications: Web Searcher, Web URL Shortener, etc.

Web Proxy Checker Pro 1.7.18
Download Web Proxy Checker Pro Now
[+] Extract proxies from web pages using PERL-compatible regular expression (regexp). The regular expression must be enclosed by slashes (/). The first group in the regular expression matches the IP, the second group matches the Port (regexp groups are enclosed by parentheses).
Example of regular expression to find proxies:
/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}):(\d{1,5})/
In this example (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}) matches the IP, (\d{1,5}) matches the Port.
