tor/src/test/test_microdesc.c
Nick Mathewson d8ef6b1548 Add a unit test for ed25519 identity parsing in microdescriptors 
This test makes sure that we parse ed25519 identities to get the
correct data from them.  It also tests:

   * That a microdescriptor may not have two ed25519 identities.
   * That a microdescriptor may not have an ed25519 identity that is
     not a valid base64-encoded ed25519 key.
   * That a microdescriptor may have an unrecognized identity type.

It will help test the refactoring of ticket31675.
