GitHound
Search GitHub for leaked API keys, credentials, and exposed secrets
...Instead of scanning only a limited set of repositories, the tool leverages GitHub’s Code Search API to analyze results from across the entire public GitHub ecosystem, including repositories and Gists. GitHound examines files returned by search queries and applies detection methods such as regex pattern matching, entropy analysis, and contextual evaluation to identify likely credentials. It can also dig into commit history to uncover secrets that may have been removed or reverted but still exist in older revisions. This capability makes it useful for security researchers, DevSecOps teams, and bug bounty hunters who need to detect leaked credentials. -

Detect It Easy
Program for determining types of files for Windows, Linux and MacOS
Detect It Easy (DiE) is a tool for determining the type and internal features of binary and other file formats. It is widely used by malware analysts, digital forensics investigators, reverse engineers, and security researchers to quickly inspect unknown files and infer their type, architecture, compiler/packer used, and internal structure. DiE supports a large variety of file formats — from common executables (Windows PE, Linux ELF, macOS Mach-O) to archives, mobile packages (APK, IPA),... -

Naeon
The safest way to store private data in untrusted (cloud) environments
Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. ... -

passcore
A self-service password management tool for Active Directory
PassCore is a very simple 1-page web application written in C#, using ASP.NET Core, Material UI (React Components), and Microsoft Directory Services (Default provider). It allows users to change their Active Directory/LDAP password on their own, provided the user is not disabled. PassCore does not require any configuration, as it obtains the principal context from the current domain. I wrote this because a number of people have requested several features that the original version did not... -

rtl2832-entropyd
Use an rtl2832 USB dongle to generate random data for the linux kernel
rtl2832_entropyd is a program that is designed to feed entropy into the linux /dev/random kernel entropy pool. It automatically forks and runs as a daemon, unless one of the testing options, -o or -t, are selected. Then it never forks. To use it, you need an rtl2832 USB dongle. They are relatively cheap (< $10 on ebay), and are actually used to listen to a broad range of radio transmissions. -

Predator encryption
Small encryption
...I have it in c++ too but I have yet to upload it. This program is good for small files but does not handle large files very well. It creates a binary key to increase the entropy of your file. It can use the key to reverse the entropy of your file. So, it encrypts and de-crypts. -

Windows Service to monitor drive c: for file events with crypto specific file extensions or with big file entropy. It does not prevent from ransomware infection! Don't use it in productive environments to prevent data loss! The Software comes without any warranty. When a alarm is triggerd it send a email and shutdown the host or disable the network interfaces. The alarm can be triggerd if locky extensions were found. Or if files were probably encrypted (big file entropy level). ... -

Password Meter
Entropy based password strength meter using javascript
This small project is password strength meter for web pages written in javascript and html. The password strength is based on the entropy of the character sets used. Entropy in this case means the number of possible combinations of lowercase letters, uppercase letters, digits, and special characters that are possible in a password. Please see the project home page at http://passwordmeter.sourceforge.net. This project was inspired by a Randall Munroe cartoon at http://xkcd.com/936/. -

passphrase-generator
Generate a set of random passphrases for you to choose from.
...The passphrase-generator defaults to only 3 words instead of the 4 suggested by XKCD, but uses a larger dictionary found in many unix like systems at /usr/share/dict/words. It also provides estimates for the entropy of the generated passphrases. The randomization is based on /dev/urandom and SHA1. See http://xkcd.com/936/ for an entertaining take on passwords vs. passphrases. See my post in stackoverflow for links to other solutions and discussions on passphrases vs passwords: http://stackoverflow.com/a/12646320/1148030 -

Entropy Monitor
Monitor of the available entropy stored within the Linux kernel
...Without random numbers these programs would generate the same results every time they run. High security uses for entropy would be applications that create cryptographic keys. Even after the key is eventually replaced, everything it was used to encrypt remains only as safe as the entropy used to generate the key. This monitor checks the amount of available entropy and informs the system adminstrator about possible bottlenecks on his system. -

MandelHash
MD5 hash used to position and color two overlaid Mandelbrot sets.
I'm using an MD5 hash of a username and password field to generate some entropy which is used to generate color pallets and positions / scaling of two Mandelbrot sets. These two images are overlaid to create interesting pictures which represent the entered credentials. I'm interested in all things security, this is mostly just for fun, but could possibly be used to help users identify mistakes in their password entry prior to submission and enforce a tighter failed password lockout policy. ... -
