topic Re: Does the Ruckus team give SHA1 or MD5 sums for the ZD image downloads or provide that information anywhere? in ZoneDirector https://community.ruckuswireless.com/t5/ZoneDirector/Does-the-Ruckus-team-give-SHA1-or-MD5-sums-for-the-ZD-image/m-p/12255#M2674 Hi Linda, <BR /><BR /> Good question. We've debated it. The images are signed, and so that internal hash serves to validate the images are correct. That doesn't mean you can't get a corrupt image, but it does mean the ZD will detect it and refuse to load. <BR /><BR /> (p.s. stick w SHA1 - the naughty boys -- and no I don't mean the NSA -- have cracked MD5) <BR /><BR /> I've referred this to our security team to see if they have any further comment.

Are you going to be supporting that information given the MR of 9.6 and going forward?

So for now we will continue as is (though we do have a big makeover coming up which should make downloads a better experience) Wed, 11 Sep 2013 20:09:37 GMT https://community.ruckuswireless.com/t5/ZoneDirector/Does-the-Ruckus-team-give-SHA1-or-MD5-sums-for-the-ZD-image/m-p/12257#M2676 keith_redfield 2013-09-11T20:09:37Z Re: Does the Ruckus team give SHA1 or MD5 sums for the ZD image downloads or provide that information anywhere? https://community.ruckuswireless.com/t5/ZoneDirector/Does-the-Ruckus-team-give-SHA1-or-MD5-sums-for-the-ZD-image/m-p/12258#M2677 Hi Keith, <BR /><BR /> Does this mean there will really be no way for ZD to install a corrupted image and in no way brick it? <BR /><BR /> Thanks.

It was about 5 years ago, when ZDs were not black yet. <BR /><BR /> So It's not improbable, but I wouldn't worry about it too much. It has limited lifetime warranty <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span> Mon, 16 Sep 2013 05:55:29 GMT https://community.ruckuswireless.com/t5/ZoneDirector/Does-the-Ruckus-team-give-SHA1-or-MD5-sums-for-the-ZD-image/m-p/12260#M2679 primoz_marinsek 2013-09-16T05:55:29Z
