It's nice that this service is trying to make it easier, but why should anyone trust tinycert? How can I trust that tinycert won't issue certificates without my concert? Or sell my private keys to others?

The commands really aren't that complicated. You can (and really should) learn how to do this if you need to issue certificates.

Also, deleting CA's doesn't seem to work.

It actually doesn't break, you just have to do the carries as you would during normal addition. You have to read from right to left (1's place, 10's place, 100's place, and so on). So you're really just converting to base 10.

5th row: 1 5 10 10 5 1

Writing this a bit backwards, 1 * 1 + 5 * 10 + 10 * 100 + 10 * 1000 + 5 * 10000 + 1 * 100000 = 161051 = 11^5.
