Hi Marcus,

The thing which concerns me is the ISOs - there are good reasons to have the 
mirrors use HTTP, but the checksums used to check the integrity of the ISOs 
should be downloaded over HTTPS from a verified source, bandwidth requirement 
for this is very low.

I am presuming that there is inbuilt trust for the official repo signatures - I 
don't recall ever being asked to accept a signing key except when adding a 
community or other unofficial repo - so all is good once the integrity of the 
ISO used to install the OS is guaranteed. We then know that updates and 
additional packages are signed with a trusted key, at least for officially 
supported packages.

This has come up before :)

The downloads themselves don't need to be SSL. Nobody should really trust a 
large download without a checksum or some other sort of error checking. Many 
people use torrents now anyway, and often they're more reliable. But the 
openSUSE web page with the checksums for the downloads should absolutely be 
SSL. This should be easy to do.

Regards,

Eoin
