I'm working on some requirements to secure our devices. On the ASA, the SSL settings has SHA1 listed as the hashing. Is there a license feature that updates it to SHA2 or greater?
That is only possible for TLS 1.2 what is not supported on your ASA. TLS 1.2 was introduced in ASA version 9.3(1) and supports ciphers with both SHA256 and SHA384. But you need one of the newer ASA-X models for that.
