rdev5 / CryptoRandom.cs
Created Mar 29, 2018 — forked from niik/CryptoRandom.cs
Buffered CryptoRandom implementation based on Stephen Toub and Shawn Farkas' CryptoRandom
View CryptoRandom.cs
/*
* Original version by Stephen Toub and Shawn Farkas.
* Random pool and thread safety added by Markus Olsson (freakcode.com).
*
* Original source: http://msdn.microsoft.com/en-us/magazine/cc163367.aspx
*
* Some benchmarks (2009-03-18):
*
* Results produced by calling Next() 1 000 000 times on my machine (dual core 3Ghz)

rdev5 / tiny_IRremote.cpp
Created Dec 14, 2016 — forked from SeeJayDee/tiny_IRremote.cpp
tiny_IRremote - Arduino IRremote ported to the ATtiny
View tiny_IRremote.cpp
/*
* tiny_IRremote
* Version 0.2 July, 2016
* Christian D'Abrera
* Fixed what was originally rather broken code from http://www.gammon.com.au/Arduino/
* ...itself based on work by Ken Shirriff.
*
* This code was tested for both sending and receiving IR on an ATtiny85 DIP-8 chip.
* IMPORTANT: IRsend only works from PB4 ("pin 4" according to Arduino). You will need to
* determine which physical pin this corresponds to for your chip, and connect your transmitter

I have two code examples that I wrote for best practices encrypting a string in c#. They are both using authenticated encryption. http://stackoverflow.com/a/10366194/637783

Randomness testing of Arduino TrueRandom
View results.md

I ran

cat /dev/urandom >> devurandom.bin

which produced 31 MB of data in a few seconds. To get numbers from the Arduino, I ran:

stty -F /dev/ttyUSB0 cs8 115200 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon -crtscts
cat /dev/ttyUSB0 >> TrueRandom.bin

which took several days to produce 93 MB of data (rate of about 3.2 kbit/s)

# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.
# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.
# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite
