timer_entropyd

| Vit | 38.37 |
timer_entropyd feeds the /dev/random device with entropy data (random values) read from timers. It does this by measuring how much longer or shorter a sleep takes, since this fluctuates by a few microseconds every time. The time for a sleep jitters due to the fact that the frequency of the clocks of the timers change when they become colder or hotter. This program does not require any extra hardware. It produces around 500 bits per second. This program is also usable with virtualized systems.

entropybroker

| Vit | 9.50 |
Entropy Broker is an infrastructure for distributing cryptographically secure random numbers (entropy data) from one or more servers to one or more clients. This prevents /dev/random from ever becoming empty. This is useful, for example, for virtual machines which naturally have no source of randomness.

y_crypto
| Pop | 28.21 |
|---|---|
| Vit | 36.02 |
The y_crypto library contains a number of PostgreSQL extension functions, primarily written in C. These include random number generation, generating hash digests, and RSA encryption, decryption, signing, and signature verification.

imapfoo
| Pop | 33.36 |
|---|---|
| Vit | 2.58 |
imapfoo allows one to quickly add email messages to a specified IMAP folder. These messages can either be composed of random hexadecimal text, data specified on the command line, generated from an input file using Markov Chains (e.g. Lorem Ipsum style content), or read from an mbox file. It is written in Perl and uses a couple of standard modules, which are all part of Debian Lenny and also available on CPAN.

Spectra

|---|---|
| Vit | 2.44 |
Spectra is a simple tool designed to aid in evaluating the quality of random numbers generated by TRNGs and PRNGs. It does this by counting the occurrences of characters within a given input file to help detect perceived bias, and then visualizes the data as colored (or black and white) pixels in an image file to aid in detection of repeating patterns. As the human mind is exceptionally good at picking up on patterns that might otherwise be difficult to detect mathematically, Spectra allows the user to rapidly make a determination on the repeatability of numbers generated from the suspect RNG.

Ace snow
| Pop | 20.52 |
|---|---|
| Vit | 21.25 |
Ace snow creates a snow falling effect for Titanium apps. It creates animated flakes which fall on the application window starting from a random position at the top of the screen and disappear when they fall below the top of the screen. The flakes animation can be paused and resumed any time. The image, quantity, and speed of the snow flakes are configurable parameters.

| Vit | 19.64 |
Lightning effect JS is an object that can draw a random lightning bolt on the page. It can create a canvas on which a glowing random line similar to lightning bolt is drawn within given page boundaries. The position, color, and thickness of the lightning bolt are configurable parameters.
