I have an automotive system component that send a signal over CAN and then another device see’s the message and responds with an answer. The initial code always changes. I have a bunch of query and responses and would like to… Continue reading Finding the algorithm when you have the query and response.
Recently I have been researching asymmetric encryption algorithms for a class, I cannot find any information anywhere on the key lengths used in any of the algorithms I’m looking into (ElGamal & Elliptic Curve Cryptograph… Continue reading Asymmetric Encryption [migrated]
Recently, a YouTube video has been making the rounds online which shows a rather astounding comparison between two printed models of the US Capitol. Starting with the line “3-D PRINTERS CAN NOW PRINT TWICE AS FAST”, the video shows that one print took four hours to complete, and the other finished in just two hours by virtue of vibration reducing algorithms developed at the University of Michigan. The excitement around this video is understandable; one of the biggest limitations of current 3D printer technology is how long it takes to produce a model of acceptable quality, and if improvements to …read more
Are there encryption algorithms that are “more suited for” (i.e. provide greater security when) encrypting certain types of content?
For example, if I have a PDF file that I need to encrypt, is the fact that the content to b… Continue reading Suitability of encryption algorithms for different content types

An algorithm was able to tell whether subjects had studied a house or face before going to sleep based on electrical activity in their brain. Continue reading This Algorithm Can Tell What You’ve Learned Before Going to Sleep
Let’s say we are using 3 different length passphrases and 3 different algos to encrypt sensitive data, e.g:
gpg –symmetric –cipher-algo CAMELLIA256 < input.zip > output1 (random 100 characters length passphrase)
gpg… Continue reading Is it more secure encrypting 3 times with GPG?
What algorithm is the best to use for storing, sending passwords, account data, and other information between desktop apps over the network.
Looking for the best crypto-resistive algorithm to use in C# applications.
The inf… Continue reading What is the most crypto-resistive algorithm to safely send information?
[RoboAvatar]’s Chess Robot consists of a gantry-mounted arm that picks up chess pieces and places them in their new location, as directed by the software. The game begins when the human, playing white, makes a move. When a play has been made, the human player presses a button to let the robot to take its turn. You can see it in action in the videos we’ve posted below the break.
Running the robot is an Arduino UNO with a MUX shield as well as a pair of MCP23017 I/O expander chips — a total of 93 pins available! Thanks to …read more
