Pretty straightforward question. Take the image here:
Does it come with a checksum, which I can verify against after I have fully downloaded the file?
This question goes for any file downloaded, and in my particular case; I do not care if the file on their end has been corrupted, but rather that I can check BEFOREHAND what that file's signature / fingerprint / digest / hash is; Can I do that?
The reason I want to do this, is because I want to bank those hashes and put them into a database, where I can ascertain if I have downloaded that particular file before hence saving bandwidth. Thanks.
