When A MD5 hash from a file dose the hash generates for the File name ? .. or how unique is the MD5 hash from file to file ?
MD5 is long and good enough to prevent random collisions between two files.
But if you have an attacker that can control the files, he can easily create two files that have the same hash. This is because MD5 has collision vulnerabilities. Consider using another hash, such as SHA1. Git uses the SHA1-Hash of files to identify them.
