How to Crack Software (Reverse Engineering)

In this video I showcase techniques for cracking different types of crackmes.

2:20 First CrackMe (Product Key derived from username)
10:12 Prebaked Key
11:28 A twist on the Windows 95 Keygen algorithm

A keygen without music is like a TV without color.

"So... the main benefit of a keygen is that--" *Activate Windows notification pops up*

[Elaiden]

This feels like information being passed down from one generation to the next one to make sure it isnt lost

for educational purposes everyone must know that eric will put on cat ears at 100k

[Doyle]

Watched the whole thing with no understanding, you explained this very clear and descriptive, after 16mins I still have no idea well done

[frogz]

nice, btw everyone who thinks this is JUST to steal software fails to see the potential, there is enough people who crack commercial software that you'll never have to worry about finding it, learning to crack on the oter hand can help you in niche fields such as having an old critical exe in use that the source is YEARS ago gone, for example the ticketing system for your air line running on a c64.... 100% unrecoverable source, using these same techniques you can tease the required info out of the compiled program to re-create it new without original source

You know it’s a good day when Eric uploads.

Please do more of this, there's not so many people teaching reverse engineering like this.

i know nothing about coding or software, and i have no clue whats going on but i still find this so interesting!

[IDESTROYER]

Eric loves Serial Experiments Lain.

Myth Confirmed.

I developed a software product 20 years ago and lost the source code. All I have now is the product itself and the keygen. I always wanted to put the keygen into a shop, so people could get the key after they bought the software. Until then I was sending the keys by email. I tried to understand the algorithm with ghidra and some other tools. I failed because I had no idea what I was doing.

I will try now with this excellent video. Thanks for this.

downloading this video before youtube deletes it

Most Important: write a banger chiptune

To my this will always be fascinating, I do work in IT but when I watch videos likes it suddenly feels like I dont.

It is absolutely crazy that people can learn this.

Well done.

[NeoDesu]

its 6:36 AM, I haven't slept yet, I don't crack, I don't write code, I'm not a devoloper or a programer (still trying to convince myself to learn), and I just sat here and watched the whole video. I am cooked 💀

Everyone should learn how to crack, reverse-engineer, or exploit software. Purchasing something should be a means of supporting creators, not an unfair deal (yes, I'm looking at you, Adobe).

[SaayonC]

Honestly I love this channel, it's literally the main stuff i'm interested in.

[TheInfluencerDigestX]

Best reverse engineering channel on youtube, keep it up man!

[nrzt]

Eric, know that you can't escape from that reply. We'll never forget about it.

The real beauty here is this is done on an UNActivated Windows
