Add the SHA256 Hash algorithm to VPN Firewall FVS336Gv3

Hi,   I just got a certificate which the hash algorithm is SHA256.   But my vpn firewall only allows SHA1.   Can you please fix this?   Thank you very much.   Best regards

Just throwing this out here folks.....

 

SHA-1 has been officially broken. Not just "proof of concept", but out in the wild; Github just suffered a major data corruption issue due to SHA-1's weaknessess.

NETGEAR, you NEED to FIX THIS! Your VPN doesn't even support SHA-256 as the transport hash algorithm, much less for certificates. This is VERY UNSAFE!

 

ALL CERTIFICATE AUTHORITIES ARE NO LONER ISSUING SHA-1 CERTS!!!
