It reports mitigations and hardening features such as RELRO, stack canaries, NX, PIE, CFI, FORTIFY_SOURCE, and seccomp. ### Project history The original checksec was written by Tobias Klein as a Bash script in 2011. The maintained project is a modern Go rewrite distributed as a single static binary while retaining the familiar checksec purpose and name. ### Adoption history The project is distributed through release binaries, Linux package formats, a container image, Go installation, and several operating-system package managers, making it a common lightweight hardening check in developer and security workflows. ### How it is used Typical commands inspect one file, recursively scan a directory, audit a process by PID, or examine the running Linux kernel. Machine-readable CSV, JSON, XML, and YAML output makes it suitable for scripts and CI policy checks. ### Why package nerds care checksec packages a broad set of binary-hardening checks into one small CLI. It is useful after compilation or packaging to verify that toolchain and linker hardening flags survived into the shipped artifact. ### Timeline - 2011: Tobias Klein wrote the original Bash implementation. - 2014: The current official GitHub repository was created. - 2026: The Go-based 3.x series was distributed as static binaries, native packages, containers, and source builds. ### Related projects - The project is closely associated with ELF tooling, Linux kernel hardening, compiler and linker mitigations, and CI systems that consume its structured reports. ### Sources - - - - ## Security Notes No matching local secret-handling manifest was found for checksec.
