Hi is there any solid algorithm or solution where I can refer to for preventing dos (denial of service)attack on my apache server ? I did the dos attack using slowloris in ubuntu and switchblade in windows targeting my local server.

This question has been burning in the back of my head for the past few days, and a quick Google search doesn’t yield any usable results.
As the title suggests: What is the easiest-to-understand post-quantum asymmetric cryptographic algorit… Continue reading What is the simplest post-quantum asymmetric cryptographic algorithm?
Given a bunch of pairs like these:
My – UUID number 1
secret – UUID number 2
is – UUID number 3
Decode the next word given only the UUID of the message.
I spent yesterday checking out the web for hints to help me understand if and how … Continue reading Decoding UUID4 (version 4 variant 1) given a minimum number of decoded pairs
I would like to compute the MD5 hash of a file
The file is uploaded to my webserver by my clients
The file is uploaded in pieces (called chunks)
The client also sends the md5 hash of the file so that the file integrity could be verified
Th… Continue reading Is MD5 hashing possible by divide and conquer algorithm
I have a local application that normally authenticates against a remote Active Directory server. If the local host loses network connectivity, a special local account becomes available for login. Currently, that account has a standard pass… Continue reading Is there any secure method to have recoverable passwords?
After reading a comprehensive paper [1] covering various kinds of generalized Feistel networks, I’ve tried to implement the Unbalanced Numeric Feistel variant, which relies on modular arithmetic for splitting and joining an integer in two … Continue reading Unbalanced numeric Feistel network implementation [migrated]
Which block (cipher) algorithms are the most popular and most used today?
What parameter values (block length, key length) are now considered standard (safe).
I created a trading algorithm which I want to sell. People would be able to buy the "bot" at my website and it would run from there on (if this is even safe to do).
What is the best way to secure my algorithm its code? I created … Continue reading How should I protect an algorithm that I want to sell?
Recently, [Jabrils] set out to accomplish a difficult task: porting a quantum-inspired algorithm to run on a (simulated) quantum computer. Algorithms are often inspired by all sorts of natural phenomena. For example, a solution to the traveling salesman problem models ants and their pheromone trails. Another famous example is neural …read more

With social media and online services are now huge parts of daily life to the point that our entire world is being shaped by algorithms. Arcane in their workings, they are responsible for the content we see and the adverts we’re shown. Just as importantly, they decide what is hidden …read more
