Hi,

given an SSL* or respectively an SSLCIPHER* struct, how can I figure out the length of the IV used by the negotiated cipher of the handshake?
I noticed that EVP_CIPHER has a metod to query this information, but I also don't find a way to get an EVP_CIPHER from SSL*.
Any pointers (heh) would be very helpful, thanks.

Cheers
