Hey TryNinja, thanks for the reply.
i use a windows system & cant do these commands.
also- i dont want to install additional softwares like gpg4win etc.
what i can do is, use the inbuilt certUtil in Windows cmd to do sha256, sha1, md5 hashes.
it would be truly great, if you please do a quick hash of the file and post below. thanks.

Well, you shouldn't completely trust me, but I did get the hash of my electrum-3.3.2-portable.exe file downloaded from Electrum.org;
SHA256
22489e88966a9939cf34a94878f7ddf1dad140cce28ebe5339af6212afa611be
SHA1
312afce51cbd22e8e6a93cc5611e03c14995172f
MD5
5e9bf05766292e74ebfb08baf15888a2
TLDR: They match.
