Hi, I need help. I can't figure out why on my printed circuit board, I keep getting the warning of missing and/or incomplete external milling paths. I'm new to Fritzing.

So is the entropy source then the source that produces like a random sequence of something?
@BambiOnIce19
@BambiOnIce19 2 жыл бұрын
So the keys need to be random, as in, there is absolutely no pattern (no repetition), and therefore it is unbreakable? :)

@BambiOnIce19 2 жыл бұрын
These brute force attacks... they don't sound very elegant, really. Surely there can be other ways to attempt to break the patterns...

It seems to me it is all about the patterns...:)
@BambiOnIce19
@BambiOnIce19 2 жыл бұрын
By that logic, you would want to create a cipher where the pattern is not detectable?
@BambiOnIce19
@BambiOnIce19 2 жыл бұрын
so you are looking for patterns to break the cipher?

so the key to figure out the secret is to obtain the actual key/s, right? So at which point do you exchange your keys? Before, or during, communication with other parties?

Am I missing something? You wanted to connect C1 ground to U1 ground and struggled to find a path, but C2 ground was already connected to U1 groiund, so why didn't you connect C1 ground to C2 ground on the top or bottom layer, and then you'd have been there?

This was amazing, thank you! Are there any good video series that show the math behind more of these theories? Or how to create such systems in code? That would be interesting as well.

I appreciate your kind words. You should check out the wikipedia articles on the topics you are interested in. They are very well done, and tend to contain both the math and some sample implementations.

I'm glad I could help! I wish I could take credit, but the truth is that if you already have a basic background in circuits/schematics, then basic PCB design isn't hard at all.

@@ryanriley5591 Feel free to take these credits! What i meant was observing and following the whole process after(!) seeing some stuff running on the breadboard. I got my hands on the great Fritzing, but i think, its not that explanatory as a beginner would need. IMHO, they may have arragend the panels in the wrong order.. :-) The schematics should come first, followed by the breadboard (b.t.w. called "Steckplatine" in my german version...) I also got furios, when i tried to change the capacity-value of C3, but a moment later i learned, that this is a 'normal' Fritzing's behavior and how to work around. This was extremly useful! So thanks for that! And now i am looping over your 555-Lesson. Just to understand, what i (or we) actually did there an hour ago... :-)

i downloaded keepassx software for windows ... it is available as zip of binaries etc ... how do you verify sinatures ... currently (2020-09-24) it shows a line like following: All downloads and Git tags are signed with the key 164C70512F7929476764AB56FE22C6FD83135D45 what does it mean and how i can use them to verify ... of course it has another link to a folder with a bunch of files and .sig files ... clicking on a .sig files simply saves it ... my problem is if verifying needs a software then that software itself may infect my computer ... i am irritated by whole bunch of software publisher giving these verify secion without any instruction on how to use them ... would it not be nice if i download a file or zip and upload to some site giving link to web page downloaded from and let that site determine integrity of software? like hybrid-analysis site does?
