it seems like it's not possible to create keys and certificates's internal name, that's end with an underlined followed by an number (e.g. ABC_123).
Well, it was possible to create a certificate with the internal name "ABC_001". The name of the key was automatically changed from "ABC_001" to "ABC".
But I can not create a certificate with the internal name "ABC_002" - that will be changed to "ABC"...
Is there any way to use such names??
