Configure SealSign 2.0 on Linux

The SealSign 2.0 client solution lets you sign multiple documents using a watched folder approach.

Prerequisites

Linux operating system
DigiCert® Document Trust Manager credential ID
DigiCert ONE API key or API token authentication certificate
Java version 14 or higher
SealSign system environment variable

API Key

An API key is a unique identifier generated by the server to authenticate a user or calling program to an API. The API key acts as the first factor of authentication when connecting to DigiCert® Document Trust Manager client tools.

To create an API key:

Sign in to DigiCert ONE.
Navigate to the Profile icon > Admin Profile > API tokens.
Select Create API token.
Enter a name for the API token and how long the API key should be valid.
Select Create.
Copy the generated API key and keep it in a safe place.
Nota
If this is lost, a new API key must be created.
Select Finish.

API token authentication certificate

To generate API token authentication certificate:

Sign in to DigiCert ONE.
Navigate to the Profile icon > Admin Profile > Authentication certificates.
Select Create authentication certificate.
Enter a nickname for the authentication certificate and how long the authentication certificate should be valid.
Select Generate certificate.
Copy the generated certificate's password and keep it in a safe place.
Nota
The certificate's password is only displayed only once. You cannot access it after you select Download certificate. If you ever lose the password, you will need to generate a new authentication certificate.
Select Download certificate.
Save the authentication certificate to your computer.
Nota
You cannot download the certificate again. If you don't download the certificate or lose it, you'll need to generate a new authentication certificate.
When ready, select Close.

Credential ID

Your credential ID is the nickname of credential in DigiCert® Document Trust Manager.

To copy your credential ID:

Sign in to DigiCert ONE.
Navigate to DigiCert® Document Trust Manager > Credentials.
Hover your cursor over credential nickname.
Select the Copy icon.

Install Java

Download and install latest java 14 or higher before installing the application.

Create SealSign system environment variable

To create new system environment variable on Linux:

Open .bashrc or .bash_profile file in text editor such as vi or nano.
Add this line to the bottom of the file: export SEALSIGN_JAVA_HOME=/path/to/java
Nota
Replace /path/to/java with path to your Java installation directory.
To encrypt sensitive data, add variable name SEALSIGN_ENCRYPTION_PASSWORD. In the variable value, enter your password which will be used for encryption of sensitive data in configuration file.
Nota
('user-api-key' and 'user-pin') must be encrypted in the configuration file if you add this variable name.
Save changes.
To reload the modified environment variables, run command:
“source ~/.bashrc”
To verify that SEALSIGN_JAVA_HOME variable is set correctly, run command:
“echo $SEALSIGN_JAVA_HOME”
