Extracting default certificates

Procedure to extract and convert default certificates generated in your current version prior to upgrading.

About this task

If you are using default certificates, extract and convert them before you start the upgrade. Perform the following steps:

Procedure

  1. Set the HCL Workload Automation environment.
  2. Browse to one of the following paths:
    version 9.5 and later
    TWA_DATA_DIR/usr/servers/engineServer/resources/security
    version 9.4 and earlier
    TWA_home/WAS/TWSProfile/etc
    and run the following commands to extract the master domain manager certificates:
    keytool -importkeystore -srckeystore TWSServerKeyFile.jks 
    -destkeystore server.p12 -deststoretype pkcs12
    openssl pkcs12 -in server.p12 -out tls.tot
  3. Open the tls.tot file with any text editor.
  4. Copy the private key and public key into two separate files named respectively tls.key and tls.crt.
    where,
    tls.key
    is the private key
    tls.crt
    is the public key
  5. Copy the contents of the tls.crt file into a new file named ca.crt.
  6. Create a file named tls.sth containing the passphrase you have specified for creating the .p12 certificate in step 2, encoded in base64 format. To create the tls.sth file, use the following command:
    secure -password your_password -base64 e -out tls.sth
    If you are using a version earlier than 10.x, you can find the secure script in the installation package of the 10.2.1 version you are upgrading to. You can launch the script from on of the following paths:
    master domain manager and agent
    <10.2.1_extracted_image_dir>/TWS/<interp>/Tivoli_LWA_<interp>/TWS/bin
    Dynamic Workload Console
    <10.2.1_extracted_image_dir>/DWC/<interp>/bin
    where
    <interp>
    is the operating system you are installing on
  7. Extract the client certificates from the TWA_DATA_DIR/ssl/GSKit folder by running the following command:
    gsk8capicmd_64 -cert -extract -db path_to_TWSClientKeyStore.kdb 
    -stashed -label client -target client.crt
  8. Insert the client.crt in the additionalCAs folder when providing the certificates to the installation script with the sslkeysfolder parameter.
