[iaik-jce] Use of special Provider with S/MIME
my provider works now fine with all RSA Demo programs. But I have a "small"
problem with signing of S/MIME messages. If i sign a message the RSA Cipher
asks two times for user verification (PIN), because it runs the encryption
two times with the same hash information. Why is this necessary?
Btw, I use TCOS 2.0 card form Deutsche Telekom (e.g. German Digitale
The provider only supports RSA cipher incl. Padding. It is developed by
myself based on OCF.

You should put this provider in front of the IAIK provider and it should
implement the algorithms you want to be used.
Btw, which smartcard do you use and was the provider delivered with the card
or did you develop it on your own?
