Hi: when entering the web browser, a page sent by Debian presents me with a button saying "Download Debian 7.4". I clicked on it and downloaded the ISO image (netinst). But nowhere did I find its checksum. I've searched with the string " debian-7.4.0-amd64-i386-netinst.iso" in Google but in vain. Where could I get the checksum (md5sum)?

Thank you rokytnji. Unfortunately the file name ebian-7.4.0-amd64-i386-netinst.iso is lacking in that list. Running md5sum, I find a8c159...4783ee for this ISO image file. I cannot believe there is not a means of verifying, I don't say the autenticity, but the mere integrity of the file. Mounting the image, I find file md5sum.txt, with the hundreds of checksums for every file in the image. But there should be a checksum for the whole image or some other means of verifying the image as a whole.

EDIT: it seems it is expected that one verifies the files one by one. That is what I did.
