Blog Articles and information on C# and .NET development topics

For the past two years, all Cyotek products have been digitally signed, providing some peace of mind that when you download one of our products you can be certain it hasn't been tampered with.

At some point in the last few days, COMODO have revoked the certificate we use, for reasons I'm still trying to ascertain from their support department. The net result of this is every Cyotek product released in the past 10 months is now unusable, as when you try and start any executable, it will immediately crash due to the revoked certificate.

Emergency releases of most products have been released without digital signatures until we obtain a new certificate from another CA (clearly we will not be using COMODO again as no matter what their reasons for doing it, it has been handled in just about the worst way possible).

There is a caveat with the new builds - they haven't been as thoroughly tested as they might otherwise be. But given the number of exceptions being logged from the now completely broken products, it's the lesser of two evils.

If you are affected by this issue please visit the appropriate product page to download the interim version sans digital signatures.

New properly signed builds will be posted as soon as possible.

We are sorry for the inconvenience for this incident, we did not receive any sort of notification from COMODO about their actions, and their response to why they did it hasn't actually answered the question.
