moving from sha1 to sha2 for sslvpn
I have asa-5550 running 8.4(7)26, it support SHA-2 256, 385 & 512K per release note;
Currenlty, we are using SHA-1 for sslvpn (client & clientless) and would like to migrate to SHA-2 certificate;
However, under Configuration --> Remote Access VPN --> Advanced --> SSL Seetings ... I dont see any SHA2 encryption algorithms. All i see are ssl encryption aes256-sha1 aes128-sha1 3des-sha1....etcs
Question - how to enable sha2-256 encryption?
Any help is much appreciated, thanks
