Hi Patrick , ThanQ for your information , my intention also to use pkcs funtions only , but the problem is I am not understanding how to use them. for that only i am asking for any application program that will do the signing and verification . and there is no clearity in those funtions which algorithems they are using for signing and verification .
for suppose i gave some digested data (sha1) for signing , then i do not know which algorightms or cipher suits it is using internally.
