sha1collisiondetection
Library and CLI tool to detect SHA-1 cryptanalytic collision attacks in files, serving as a drop-in replacement for SHA-1 libraries.
What is sha1collisiondetection?
sha1collisiondetection is a C library and command-line tool that detects SHA-1 cryptanalytic collision attacks in files. It solves the security problem where malicious actors create different files with the same SHA-1 hash to forge digital signatures or compromise data integrity, offering a protective layer against such exploits.
Security engineers, cryptography researchers, and developers working with SHA-1 hashing in applications like digital signatures, file verification, or forensic analysis who need to mitigate collision attack risks.
Developers choose this library because it provides a fast, drop-in replacement for SHA-1 libraries with built-in collision detection, enabling automatic protection against signature forgeries and data tampering without requiring extensive code changes.
