Installations of VIMP Light, VIMP Ultimate [Standard], VIMP Corporate Campus or VIMP Corporate Enterprise require the PHP extension SourceGuardian.
This article explains the installation of the extension for Debian 9 "Stretch" 64-bit, further information on the usage can be found here VIMP GmbH - Info about the SourceGuardian PHP extension.
If you have a 32-bit system (e.g. i686), just change the wget command, that downloads the loader. You find an overview of all loaders on the SourceGuardian-website.
First create a temporary folder "loader" at /usr/src/:
mkdir /usr/src/loader cd /usr/src/loader
Download the sourceguardian package (64-bit here) directly into the new folder:
curl https://www.sourceguardian.com/loaders/download/loaders.linux-x86_64.tar.gz --output loaders.linux-x86_64.tar.gz
Now extract the file:
tar xzf loaders.linux-x86_64.tar.gz
Copy the file that meets your PHP version like this:
cp ixed.7.3.lin /usr/lib/php/20180731/
"ts" in the filenames means "Thread Safety". If "Thread Safety" is enabled (usually it isn't), copy the file ixed.5.6ts.lin instead.
Now create the sourceguardian configuration file.
cd /etc/php/7.3/mods-available/ touch sourceguardian
joe sourceguardian.ini
Enter the following lines into the file:
[sourceguardian] zend_extension=/usr/lib/php/20180731/ixed.7.3.lin
and save it.
Activate the PHP extension with the command:
phpenmod sourceguardian
The command has no output for errors or success.
Restart Apache:
service apache2 stop service apache2 start
Now the extension is installed for Apache2 and CLI and VIMP will be decrypted.
