2. Follow the steps below to validate the checksum value:
   • For Linux systems, execute the following command:

     sha256sum apminsight-javaagent.zip

   • For Windows, you can use either of the following commands:
     • Open Command Prompt and execute the following command:

       certutil -hashfile apminsight-javaagent.zip SHA256

     • Open Windows Powershell and execute the following command:

       Get-FileHash apminsight-javaagent.zip -Algorithm SHA256

3. After executing the commands, you will obtain a checksum value. Check that value with the one downloaded from the checksum file.

Sample Output:

Note: If the checksum values differ, do not unzip or open the file.

Signed JAR verification

All agent jar files (apminsight-javaagent.jar and apminsight-javaagent-api.jar) are signed with a Zoho Corp. certificate.

To verify the signature, execute this command:

jarsigner -verify -verbose apminsight-javaagent.jar

You can find the file is signed by "ZOHO Corporation Private Limited" at the end of the output.
