How to load a configuration file MD5 hash.



Article ID: KB14758 KB Last Updated: 23 Jul 2009Version: 1.0
Verifying configuration file integrity using an MD5 hash value when loading configurations through the WebUI.
When loading a new configuration file through the WebUI, the integrity of that file is not guaranteed. Is there some way to ensure the integrity of the configuration file being loaded through the firewall's WebUI?
Starting in the 6.2.0 firmware, ScreenOS now provides an optional MD5 hash text box.  This option is found under Configuration > Update > Config File (see screenshot below).

This feature now allows the user to insert the hash value of the configuration file to be loaded onto the firewall. Once the “Apply” button has been clicked, the firewall will generate an MD5 hash of its own and then compare that with the one provided from the user. If the hashes match, the new configuration file is saved on the device; however, if they do not match, the following error is returned:

Remember that the MD5 hash should be in hexadecimal format with 32 hex digits.
