Why does the SafeGuard LAN Crypt user need to be owner of a valid certificate (private key)?
The encryption profile was encrypted with the “public key” of a defined user. Therefore the user profile can only be decrypted by the “private key” of that same user. To decrypt the encryption profile, the certificate is checked each time the encryption profile is loaded. If a valid certificate is found, the user is logged on to SafeGuard LAN Crypt. If no valid certificate is found, the user is not able to work with encrypted data.
Special encryption rules included in the SafeGuard LAN Crypt encryption profiles give the users access to encrypted data. They define exactly which files in particular directories have to be encrypted by each key. The encryption profile of a user only needs to be loaded for encryption and decryption takes place in the background (transparently). The user will not be aware of the encryption/decryption tasks being performed.
Note: The certificate is not used for encrypting/decrypting the files and folders
