DNSWatch offers DNS lookup and reverse DNS lookup tools with exact performance measuring and DNS server monitoring. It also provides RBL email blacklist lookup and IP location lookup. Paid products include DNS performance monitoring starting at $1 per month, mailserver blacklist monitoring starting at $3.5 per month, and a DNS changetracker starting at $7.9 per month. The site is free to use with ads.
DNSPerf compares the speed and uptime of enterprise and commercial DNS services. It lists DNS providers sorted by DNSPerf rank based on data for the last 30 days, calculated using 40% performance, 45% uptime and 15% quality.
A guide introducing Web Authentication (WebAuthn), a W3C and FIDO specification that lets servers register and authenticate users using public key cryptography instead of passwords. It explains how credentials work, with a private key stored on the user's device and a public key sent to the server, and covers registering credentials and authenticating with them.
Reverse Engineering challenges is a collection of reverse engineering exercises contrived by Dennis Yurichev. The challenges are organized by level, type, architecture and operating system, with levels ranging from 1 to 3. The site also offers an about page.
Better Auth is a framework-agnostic authentication and authorization framework for TypeScript. It provides built-in email and password authentication, account and session management, social sign-on, two-factor authentication, and a rate limiter, and can be extended with plugins for features such as passkeys and multi-tenancy. It supports most popular frameworks and requires a database, such as SQLite, PostgreSQL, or MySQL, to store user data.
Iocaine is an aggressive defense mechanism that tries to poison AI crawlers and other unwelcome bots by serving them garbage, rather than making them go away. It is designed to be lightweight and efficient, spending as few resources as possible while making the life of crawlers more expensive. It is intended for use together with a reverse proxy.
Apktool is a tool for reverse engineering Android apk files. It can disassemble resources to nearly original form and assemble rebuilt folders, including changing an app's permissions. It can also analyze by ripping apart resources and the manifest for inspection.
