Comment(by rransom):

 Replying to [comment:1 karsten]:
 > Agreed, we should write code to check the descriptor signatures.  I
 suggest writing the code in Java, because we can create a standalone tool
 from it (as part of metrics-utils) and add it to metrics-db to check
 signatures on the fly.  I should have some Java code around that checks
 descriptor signatures.  Do you want to work on this?  If so, I'll dig out
 the code.

 Yes, I want to work on these tools, but I currently do not have a Java
 runtime around.

 > We don't collect any microdescriptors yet, and I don't know how to
 verify them.  Perhaps by having the server descriptors, just like with
 extra-info descriptors?

 Microdescriptors can be verified using the microdescriptor consensus.

 > By the way, should we start collecting microdescriptors?  If so, we
 should open a new ticket for that.

 Probably (even though no clients use them yet).  We should also
 investigate the lifetimes of microdescs.
