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.
Binary Ninja offers two free ways to try the reverse engineering tool: Binary Ninja Cloud, a browser-based tool, and Binary Ninja Free, a downloadable app for local use. Cloud supports all architectures but requires uploading binaries; Free supports x86, x86_64, ARMv7 and ARMv8/AArch64 and is for non-commercial purposes or evaluation.
CheckFileType is a free online tool that determines a file's true type, extension and MIME type from its contents rather than its extension. Users upload a file without registration, and the tool can look inside archives such as ZIP files to report the type of each contained file. Files are stored temporarily and removed after one hour.
A web-based tool that tests the IPv6 readiness of an internet domain and shows whether the visitor's own connection supports IPv6. It reports DNS-based results, including nameserver and mail exchanger records, and maintains a Hall of Fame of domains scoring five stars. It also warns when an embedded MAC-address identifies the device. The site requires JavaScript.
Certbot is a tool run from the command line to obtain and install HTTPS certificates. It can either be run once to get free HTTPS certificates or used with instructions generated for a server's software and system. Using it requires comfort with the command line and an HTTP website. The project is a project of the Electronic Frontier Foundation.
Demo is a developer resource for coding, documentation, communities, security research, or software tools.
x64dbg is an open-source debugger for Windows that supports both x64 and x32 applications through a single interface. It offers full-featured debugging of DLL and EXE files, a plugin API, an integrated scripting language and customizable themes.
