BTW, do you know what happens as bitcoin generation advances? We will end up with lots and lots of surplus bargain basement supercomputers in private hands designed for codebreaking.

BTW, the master keys are not the numbers P & Q themselves, but the relationship between them, cryptographically speaking. Because they are so mathematically difficult to crack, he's saying they were made from the backdoor. i.e. the security was designed around the backdoor itself.

Aw sh it, I saw this coming.

In simple English:

It is an equation with three inputs P, Q and Seed.

If you know the relationship between inputs P & Q then you only need to guess the third number, the Seed. Seeing as the seed is limited in size by modular arithmetic, then what you have is a clever thing; a lock that looks strong but isn't if you were the one who designed it.

In short, you have a lock that's hard for people to crack, unless you already have a set of master keys, or which there are a limited number.

In case you think you're safe, the plain vanilla versions of AES, IDEA, and RC4 all have this backdoor.

What programs use this? Virtually all financial, communications and privacy-related crypto software.

Wow, sounds like an Aspy type of mindset. Obssesive on a subject to a point where there is a disregard for typical normal task the average person would perform. Or maybe the rain drops on his head and wet pants were an idea for new crypto? I wonder what that Beker fella is doing nowadays, from searching it looks like he wrote a book on cryptocurrency algorithms, my guess is he must of word for banks on atms.

I knew a guy that did that kind of work, he would hangout and talk with me and the boys waiting for the subway trains, boring older fellow but had a genuine smile listening to us horse around.

Just had a look to see what happened to him. Took me ages, I spelled his name wrong: It's Henry Beker.

Explain this to me, I understand.
One second later, I have forgotten.
I am not a dullard by any means, but the people who do this level of mathematics are 1000 feet over the top of my head.
One company I worked for, (30 years ago), employed a chap called Doctor Henry Becker. Really nice bloke, brain the size of a planet. No common sense though; one day he drove to work with the car sunroof open when it was raining. He spent the morning walking about the place with a dark/damp patch on the seat of his trousers.
The sun-roof remained open during the course of the day, the seat got wetter, then he drove home with the sun-roof open.
That to me is what genius is all about.
