Why is asymmetric encryption less efficient than symmetric encryption?
It’s common knowledge that asymmetric encryption is in general much more expensive to compute than symmetric encryption, thus common practice is to use asymmetric encryption to establish a symmetric key for bulk data exchange. I’m not find… Continue reading Why is asymmetric encryption less efficient than symmetric encryption?
Is there a difference between encryption keys and encryption certificates?
Learning about cryptography. Experimenting with attacking the algorithm it’s self. My question regards vocabulary basically. Are encryption keys and certificates the same thing or are they different?
If they are the same, good, if not the… Continue reading Is there a difference between encryption keys and encryption certificates?
Pr0nbot is Back – and Evading Twitter Censors
A rapidly swelling botnet of Twitter accounts advertising “adult dating”-themed scam websites has at least 80,000 nodes to date. Continue reading Pr0nbot is Back – and Evading Twitter Censors
Promotional code based on numerical value
I have a field userid which has value between 10000 and 999999. I want to create a promotional code which is based on this field.
The promotional code will be used by the users to refer new users.
The promotional code chara… Continue reading Promotional code based on numerical value
How to responsibly disclose a vulnerability in a widespread algorithm?
Just to be clear, this is purely hypothetical.
Yesterday I got hit in the head with some bricks and, in the haze of concussions, discovered a perfect preimage attack on SHA2. For any given hash, I can immediately find some v… Continue reading How to responsibly disclose a vulnerability in a widespread algorithm?
Traction Control Gets More Power to the Road for Tot-Sized Lamborghini
We’ve all heard the complaints from oldsters: “Cars used to be so simple that all you needed to fix them was a couple of wrenches and a rag. Now, you need a computer science degree to even pop the hood!” It’s true to some extent, but such complexity is the cost of progress in the name of safety and efficiency. And now it seems this complexity is coming way down-market, with this traction control system for a Power Wheels Lamborghini.
While not exactly an entry-level model from the Power Wheels line of toddler transportation, the pint-sized Lamborghini Aventador [Jason] bought …read more

Rearranging hash adds no security?
I’m a rookie when it comes to Information Security so I’ve been reading a lot of the top questions on this stackexchange for the sake of learning. I came across this question that discusses hashing. In criticism of a home-b… Continue reading Rearranging hash adds no security?
How to search CMD for a specific string?
I’m developing an algorithm and I need to be able to search cmd for specific strings. Does anyone know if there’s a command for this?
Hide algorithm and variables
I have some variables in my algorithm that I would not want others to see.
Party A would write an algorithm which will use my variables. But party’s A algorithm should remain hidden i.e. I should not see it.
I run A’s algor… Continue reading Hide algorithm and variables
