2.2. Signing a Configuration Bitstream

Intel® Agilex® devices support Security Version Number (SVN) counters, which allow you to revoke the authorization of an object without canceling a key. You assign the SVN counter and the appropriate SVN counter value during the signing of any object, such as a bitstream section, firmware .zip file, or compact certificate. You assign the SVN counter and SVN value using the --cancel option and svn_counter:svn_value as the argument. Valid values for svn_counter are svnA, svnB, svnC, and svnD; svn_value is an integer in the range [0,63].
