The Signature of the OVF Package does Not Match its Content

May 19, 2020 Jordansphere VMware

Issue

I had exported an OVF template from a vsphere 6.0 vCenter and the target woud not accept the OVF unless I edited the XML and removed a specific device (this should be a different post). Thie import worked on vsphere 6.5 and 6.7 but when trying to import into another vsphere 6.0 I got the following error

 

The signature of the OVF package does not match its content. This indicates theat the package has been tampered with and is a potential security risk

ovf-upload1

 

Resolution

As I had edited the ovf I needed to recreate the hash and update the the .mf file to reflect this.

To do this I used Powershell

Get-FileHash my.ovf -Alogrithm SHA1

This will output the following

ovf-fail2

You then need to copy the Hash value and edit .mf file (ef my.mf) with an editor (eg Notepadd++)

Replace the current HASH with the new value and save the file

The import should work after that.
