...The server provides a secure and privacy-preserving backend system that enables governments and organizations to deploy exposure notification applications for Android and iOS devices. It handles essential backend functions, including receiving and validating temporary exposure keys from users who have tested positive, storing those keys, and generating downloadable key files for mobile devices to check for potential exposure matches. The system integrates cryptographic signing for authenticity, supports configurable data retention policies, and ensures user privacy by design—no personally identifiable information is stored or transmitted. ...

Web Security Basics is a beginner-friendly review of essential web security concepts that equips web developers with foundational knowledge about protecting applications and understanding common threats. The repository focuses on real-world security mechanisms and vulnerabilities, explaining protocols like SSL/TLS for encrypted communications, the principles behind CORS (Cross-Origin Resource Sharing), and widely exploited attack categories such as cross-site scripting (XSS) and cross-site request forgery (CSRF). ...

An essential utility, passgen was written in response to the lack of a useful password generator, which should be standard issue for any multi-user machine. passgen generates passwords which comply to security stds recommended by CERT, NIST and others.

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only...

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a...
