Alright, I think it is possible to substitute the image by a man in the middle attack. Tried https, no. Well, I think, SHA-256 only is not the most secure way to check validity, because iso image could be easely modified by adding a file with needed trash to make same SHA-256.
Alright, better to use any security then none... Is it? Well..

Crap! I can not download openSUSE securely! Anyone in the middle could substitute even SHA-256 file! Is it possible to download openSUSE safely somehow? Anyone?
