I did a vulnerability scan on some of our company workstations. These are workstations used by employees (dev, HR, accounting, etc.) to do their job.
One of the common result I found is SSL/TLS Certificate Signed Using Weak Hashing Algorit… Continue reading Certificate Signed Using Weak Hashing Algorithm impact on a workstation
Can anyone help me know how Facebook suggests unknown friends? Or, any references in this regards will do.
What i know is there are infinite ways in which Facebook can suggest friends. One of the ways in which Facebook suggests you frie… Continue reading What is the mathematics behind Facebook friend suggestion algorithms [closed]
I wanted to asked how can i identify what algorithm was used.
This is my code:4775467546655764575574666675577557655665456644665566456644664565465456456456575455544544654465444664436674456777456774456676444554

The question is about voting in decentralized systems. Quadratic voting is a wonderful way to reach consensus without arranging property qualifications. However, quadratic voting requires a KYC: otherwise, the attacker will simply distribu… Continue reading Algorithm for quadratic voting in anonymous decentralized systems
I’ve been given the task of generating some gift tokens which comprise a serial number and a pin number, analagous to a pre-paid credit card. The serial and pin will be printed on a card, with the pin behind a scratch panel.
My first tho… Continue reading Is a random number secure (enough) for card numbers and pins?
Suppose that 2 people have a keyed hash algorithm (that is, a MAC) with a key that they both know. How could they implement challenge-response using their keyed hash algorithm? This confuses me…
I’m curious if the origin of any successful computer virus is known to NOT have an intentional, human originator. To put it another way, do computer viruses ever “spontaneously” originate through the process of natural selection in the sa… Continue reading Are all computer viruses man-made?
