Cisco ASA

[edilson.silva1]

Hi, we have a Cisco ASA 5510:

* Software Version 7.2(3);

* License Security Plus

I would like to know if this firewall support SHA-256 (VPN IPsec)

It depends: The legacy ASAs support SHA-256 for the IKEv2 policies, but not for IKEv1 and also not for IKEv2 IPsec-proposals.

You need an image upgrade to (I think) v8.4 which probably also needs a memory upgrade for your ASA.

According to documentation, the first version of ASA to support SHA2 is 8.2(3.9).

CORRECTION:

That was for SSL VPN, sorry. IPSec on Windows/Android clients was added in 8.2(5).
