Digital Rights Technologies Enhancements

The file protection capabilities introduced in V8.1 are enhanced for MicroStation V8 2004 Edition as described in the following sections.

Digital signatures created with the 2004 Edition are not backward compatible with V8.1. If you create digital signatures with the 2004 Edition, make sure users with whom you exchange these digital signatures are also using the 2004 Edition.

Selectively enabling types of file protection

Administrators can selectively enable password or certificate protection by setting the configuration variable MS_PROTECTION_ENABLE.

To disable file protection, set the configuration variable to “0,” which is the default.
To enable password or certificate protection, set the configuration variable to “1.”
To enable password protection, set the configuration variable to “2.”
To enable certificate protection, set the configuration variable to “3.”

MS_PROTECTION_ENABLE should be used for this purpose instead of MS_PROTECTION_ENCRYPT. The latter is obsolete.

Selectively enabling types of licenses

Administrators can selectively enable the application of password, certificate, and Everyone licenses to protected files by setting the configuration variable MS_PROTECTION_LICENSE_ENABLE.

To disable license creation, set the configuration variable to “0.”
To enable password licenses, set the configuration variable to “1.”
To enable certificate licenses, set the configuration variable to “2.”
To enable Everyone licenses, set the configuration variable to “4.”
To enable all types of licenses, set the configuration variable to “7,” which is the default.”

You can enable two or more license types by adding their values together. For example, you can enable password (1) and certificate (2) licenses by setting this variable to “3”.

Unencrypting files

The key-in PROTECT ENCRYPT REMOVE enables you to unencrypt the master file without being asked to confirm the action.

Preventing file encryption

If, as the owner of a protected file, you do not want other users to encrypt the file, you can communicate this preference by marking the file with the key-in PROTECT NOPROTECT. The key-in PROTECT NOPROTECT 0 reverses the effect of PROTECT NOPROTECT.
