OK guys, I found the source of the changed behavior in 1.2.18
It is in certkeys.c and relates to the SILENT flag below ...
If one removes the CRYPT_ACQUIRE_SILENT_FLAG and re-compiles, then the old
behavior can be achieved. In other words, with the removal of this flag, one
will be prompted for the MSCRYPTO KeyName and password to login to (i.e.
acquire) the key-pair as was the case with XMLSec 1.2.13 where this was the
Hope this helps those using XMLSec on the workstation as opposed to on the
server where clearly a modal dialog prompt is not desirable.
