Aleksky I really should have thought a bit harder before posting my query - my only defence is that I was tired and it was VERY late. I take your point about forcing inclusion of the root certificate but what about intermediate certificates? While they are necessary to establish trust, they are not by themselves (i.e. without the root cert) **sufficient** to establish trust. As regards my second question - I asked because I was puzzled as to why my test signature was verifying OK in the apparent absence of the root certificate! It was only after you replied that I realised that the root certificate was NOT absent (the signing and the verification were happening on the same (windows) machine so the root certificate WAS most certainly available!) so everything was working exactly as it should!
Thanks for your patience - and for a very effective library!

You don't want to. Root certificate (trusted certificate) establishes "trust" and it should be communicated to the verifier by the outside trusted channel. > 2/ Should the signature verify in the absence of the root certificate? No. See above. You might want to read a book on PKI/certificates.
