For my work I'll need to provide my customer a specific file which will be the result of the work I have done for them.
To protect the integrity of the work I have done and to guarantee it has never been modified, I intend to add a checksum to my documentation which will be provided with the file.
Since MD5 and SHA-1 are not secure for a long time now, I was wondering if we were still using them for this purpose or isif there are better algorithmalgorithms which could do the same job but safermore safely.
I'm looking for the best reliable solution. I'm aware that a 100% proof will never be possible but iI was wondering if MD5 was still rated "good" for this purpose or if there are really new and safer tools.
