This website is a personal technical blog by Nikolai Tschacher, presenting in-depth explorations, research, and self-built projects in IT security and computer science. It is aimed at developers, security researchers, and engineers interested in practical, low-level technical analysis and novel solutions.

Key content and features include:

• IP Address and Network Analysis: Detailed articles on mapping IP addresses to autonomous systems (AS) and algorithms for identifying datacenter or cloud provider IP ranges, providing actionable methodologies for network intelligence.
• Protocol Security Research: Investigations into TLS protocol differences (TLS 1.2 vs. 1.3) and techniques for client fingerprinting, offering insights into modern web security and identification mechanisms.
• Custom Tool Development: Documentation and releases of original software projects, such as db.js, an in-memory database with persistent file storage, demonstrating a hands-on approach to solving engineering problems.
• Browser and Timing Analysis: Explorations of high-precision JavaScript timers and their potential applications beyond well-known CPU attacks, covering relevant browser security topics.
• Practical Code and Data Sources: Articles often include necessary code snippets, data sources, and clear explanations of non-trivial processes, serving as a resource for replicating analyses or building similar tools.
