Capslock
Tool to remap Caps Lock key behavior on Windows systems
Capslock is a command-line tool for analyzing the capabilities of Go packages to reveal what privileged operations their code and dependencies can perform. Rather than detecting vulnerabilities, Capslock focuses on identifying capabilities — permissions implied by calls to sensitive or privileged standard library functions, such as file system access, networking, or process control. By following transitive call graphs, it classifies which security-sensitive operations each package can reach,... -
