AES-NI for RRAS?

-

i'm using openvpn on linux uses aes-ni significant performance improvement.  since not devices have openvpn client available, add l2tp , sstp vpns using windows server 2012.  unfortunately not finding whether routing , remote access in windows 2012 uses aes-ni when cpu supports it.

does rras in windows server 2012 use intel's aes-ni on supported cpus speed l2tp vpns use aes encryption?

can windows server 2012 utilize aes-ni sstp vpns, goes through iis? 

hi daviddemk,


firstly, l2tp message encrypted 1 of following protocols using encryption keys generated ike negotiation process: advanced encryption standard (aes) 256, aes 192, aes 128, , 3des encryption algorithms.


quote vpn tunneling protocols


and, according article of intel, aes-ni instructions can used in application uses aes encryption. aes used in several applications such network encryption, disk , file encryption applications. file-level , disk encryption applications use aes protect data stored on disk. networking applications use encryption protect data in flight protocols encompassing ssl, tls, ipsec, https, ftp, ssh, etc.


details, intel® advanced encryption standard instructions (aes-ni)


hope helps.
