Re: CryptDecryptMessage with CSP pin
Hi,
I need the same funcionality, but couldn't find any usefull
information on it so far. The only thing I got is mention of
PP_KEYEXCHANGE_PIN in the smart card cryptographic cookbook, e.g.:
"There are two ways for the CSP to receive a PIN; CryptSetProvParam
PP_KEYEXCHANGE_PIN and PIN request UI."
However - I couldn't even find the definition of the
PP_KEYEXCHANGE_PIN , not to mention example source code. Can you
please share a pointer to some usefull info ? Thanks :)
Cheers,
ÂŽeljko
