Could Mikrotik provide MD5 checksums for installation packages and a console checksuming tool ?

I just nearly lost access to one router because of this, the installation package got corrupted during download, it installed, but the sshd was missing. Luckily the winbox worked, so I was able to reupload good package.

There must be a way to verify the file integrity before commencing an upgrade.

Hmm, if no check is being done that is indeed very bad, one corrupt download could mean a tower climb! Are you sure the download was bad and it wasn't something else?
