[1/🧵] A brief #thread on how to properly download and verify your newest #IOTA #Firefly Windows version. 😉

[2/10] You might be wondering why @iota doesn't allow you to download & upgrade the version via the client.

To be honest, this would definitely improve usability (#UX), but it would also need the user to trust the DL content.

That is precisely what we do not want with #crypto.

[3/10] Who knows whether the network path from #github to your PC wasn't intercepted and a man in the middle (#MITM) replaced your downloaded program with a slightly different one.

To ensure that the program you are installing is the one meant for you, verify the #hashes. 👀

[4/10] Before we get into the technicalities, let me demonstrate & prove to you that altering just a small portion of whatever you're hashing results in an entirely different hash

1⃣ — A notepad file beginning with the letter "a"
2⃣ — A notepad file beginning with the letter "b"

[5/10] The same is true for any other program, including the #firefly desktop wallet.

So, to be absolutely certain that nothing has changed, we must manually (I know, it's a pain) compare the #hash that we produced ourselves to the one that was given to the public.

#LFG 🤓

[6/10] Step 1⃣ — Download the software

First, we download the latest application from #github as normal.

For this, we examine the release candidates that have been publicly *cough* released. 😅

github.com/iotaledger/fir…

[7/10] Step 2⃣ — Open CMD.exe

Next, we launch #cmd.exe (without administrative privileges) and enter the following:

▶️ cd %userprofile%\Downloads

(We are now inside the folder containing the #IOTA #Firefly wallet software.)

[8/10] Step 3⃣ — Generate a SHA256 hash

To accomplish so, enter the following command after accessing your "Downloads" folder:

▶️ certutil -hashfile "firefly-desktop-1.7.1.exe" SHA256

[9/10] Step 4⃣ — Compare the hashes

We're almost there! 😅

The next step is to compare the #SHA256 hash we generated with the one the @iota Foundation published on #github to determine whether or not our download was tampered with.

[10/10] That seems good to me! 🥳
