 == What is a signature and why should I check it? ==
-When you download a file from the internet, you don't have a good way of knowing if it may have been tampered with.  It's not beyond the realm of possibility that someone could release a patched version of pidgin that transparently captured your passwords and uploaded them to some server.
 
-This is where signatures come in - file signatures are very similar in concept to the idea behind signing both the back of your credit card, and a credit card receipt.  The signature is a verification that the file came from who it was expected to come from.
+The fact that you're using pidgin means that you have some level of trust in the authors, but It's not beyond the realm of possibility that someone else could make an "evil" patched version of pidgin which would steal your sensitive data without your knowledge.
 
-You probably have noticed that vendors frequently don't bother to compare the signature on the receipt to the signature on the back of the card, which makes it so that anyone could have been using the credit card (let's pretend that the signature on a credit card slip isn't trivially easy to forge).  Similarly, if you don't verify the signature on a file, even if the file is signed, you don't have any confidence that it came from where it was expected to come from.
+When you download a file from the internet, unless you take additional steps, you don't have a good way of knowing if the file may have been tampered with.  If you were to somehow end up with the "evil" version instead of the official release, how would you know the difference?
 
-Due to the nature of how signing works, an additional benefit is that if you verify the signature, you can be confident that nothing got corrupted during the download process - the file you have is exactly as it was when it was signed.

+You probably have noticed that vendors frequently don't bother to compare the signature on the credit card receipt to the signature on the back of the credit card.  When this happens, the vendor can't be confident that the person using the card is actually the card's owner.

 == Source Tarballs ==
 The source tarballs (`pidgin-$VERSION.tar.gz` and `pidgin-$VERSION.tar.bz2`) are signed with [http://www.gnupg.org/ GPG] by one of the following people:

 As of Pidgin 2.10.7, the Windows installers are signed using the [http://msdn.microsoft.com/en-us/library/ms537361(v=vs.85).aspx Microsoft Authenticode] signing mechanism by Daniel Atallah using a key with a thumbprint of `C5476901C3C63FABF54CEBA9E3F887932A9579B5`.
 
 The signature can be verified most easily by using Windows Explorer to look at the Properties of the installer executable.
-In the "Digital Signatures" tab, you can look at the Details of the signature, "View Certificate", and compare the (case-insensitive, whitespace-insensitive) "Thumbprint" value in the "Details" tab to the value listed above.[[Image(windows_cert_verify_thumbprint.jpg)]]

 Alternatively, the signature can be verified using Microsoft's `signtool.exe` utility (which, unfortunately, in order to obtain, requires that you install the at least parts of Microsoft Platform SDK).
