Hi, AES_GCM is supported on OpenSSL-1.0.1 Regarding support on OpenSSL-0.9.8, have found patch on link below. http://rt.openssl.org/Ticket/Display.html?id=2092&user=guest&pass=guest
>From various opensource discussion, it seems it cleanly apply to old version. Is it ok for this patch to be used on older versions or in order to use AES_GCM, upgrade to new openssl is mandatory? Mukesh
