Well, the result on my side is as follows...


"must be sorted starting with the certificate to the highest level (root CA).":

I would like to assert the intended meaning of this. To me it means "from the 
assigned certificate down to root ca"! My English bug? How was that meant 
really?
Suppose Ludolf's right about "from root-ca to the assigned cert.": c_rehash 
gives equal hashes for all @[root-ca.pem, server.descend.pem, 
client.descend.pem]...


On the other hand, when tried from assigned down to root, the self signed 
root-ca is tried to verify and it fails, saying "VERIFY ERROR: depth=1, 
error=self signed certificate in certificate chain" and "certificate verify
failed".
