Use in environments that do not connect to the network

 If you want to use thilmera in an environment that does not connect to the network at all, it may not start due to the fact that the certificate of the digital signature certificate has not been confirmed or it can not be determined whether the body is genuine or not.
 In the explanation of the certification authority, "* It is designed to check online whether the certificate used for the signature at the time of signature verification is not revoked, at that time access to the system of the global sign has occurred I will.
 * You can change the setting whether or not revocation checking is done in the client environment. "It is explained.

 It is possible to set not to perform the revocation check from the detailed setting in the Internet option of the browser, but because security is not desirable, please be careful about setting change.

Security warning
I'm trying to install a certificate from a certification authority (CA) that claims that the issuer is:


We can not verify that the certificate is actually from "GlobalSign". You need to contact "GlobalSign" to check the issuer. The following numbers are useful in this process:

Thumbprint (sha1): D69B5611 48F01C77 C54578C1 0926DF5B 856976AD

When you install this root certificate, the certificate issued by this CA is automatically trusted. Installing a certificate with a thumbprint that has not been confirmed is dangerous from a security point of view. If you click [Yes], you will recognize this danger.

Would you like to install this certificate?

Yes (Y) No (N)
To agree to the above warning text, please press [Yes (Y)].

6. Once the import is complete, restoring the backup of the certificate is complete.
