Which algorithm is better to use as an indicator of changes in the content of the file?

The question is quite simple, I don't need a long detailed answer. What I'm trying to do, I wrote a small console program that creates components from svg -> react (why it doesn't matter to me) everything is fine here, but I would like to create a manifest for the created components in a json file, so that when the script encounters the name svg of the file was able to check whether there is such an element in the manifest and compare the hash keys, whether the content in the svg corresponds to the content in the manifest, so I’m thinking of using md5 to generate the hash (I’m not interested in security), I just need a small hash string by which I can would be to compare whether the content in the file has changed, so the question is whether there is something more more effective for solving this problem, the main thing here is speed, or md5 will be the best choice?
