How to setup digital signatures on the LabCollector ELN
The OPENSSL_CONF environmental variable, if set, will be used as the path (including filename) of the configuration file.
The SSLEAY_CONF environmental variable, if set, will be used as the path (including filename) of the configuration file.
Basically, just create the folder C:\usr\local\ssl (folder usr then local then ssl) and copy openssl.cnf provided in \LabCollector\php\extras
In System Properties > Environment Variables, ensure that OPENSSL_CONF is pointing to the file path as well, then restart the computer/server.
Using Signatures in the ELN
Once set up this will allow the application of signatures to specific pages within the ELN.
At the bottom of the ELN page is a button to close and sign the page. Clicking this button will provide a prompt to re-enter the user login credentials. The time stamp, user and signature information will be presented. The content of the page is then locked. If your signatures are not enabled or set up properly, the page can be closed without the application of a signature.
