# Generate a SHA-1 thumbprint

Generate an SHA-1 thumbprint using the JWT provider's sys\_id, the Java Key Store \(JKS\) certificate's sys\_id, and the JKS certificate's alias to the GraphCertificateOAuthTemplate script.

## Before you begin

Role required: admin

## Procedure

1.  Navigate to **All** > **System Definition** > **Scripts-Background**.

2.  Paste the following script to generate the SHA-1 thumbprint value.

    ```
    var certId = "<sys_id of the certificate record>";​
    
    var certAlias = "<alias name for the certificate>";​
    
    var gce = new GlideCertificateEncryption();​
    
    var thumbprint = gce.getThumbPrintFromKeyStore(certId, certAlias,"SHA-1");​
    
    gs.log(thumbprint);​
    ```

3.  Select **Run script**.
