cnMaestro 2.1.0 (On-Premises)

The current 2.1.0 release is using sha256 hashing if you extract the ova file and see the .mf file (the previous version 1.6.1-r10 was using SHA1)

Vmware changed the default hashing from SHA1 to SHA256 from OVFTOOL 4.2 onwards

If you are using vShpere C# client to import the latest OVA then you might run into an issue which says

"Invalid OVF manifest entry"

You need to convert the OVA from sha256 to sha1 using ovftool

Here is the KB article from Vmware on how to do it.
