  Generating a Password Hash

  If you're including the optional security-master-user-password-hash parameter to use with the optional security-master-user-name parameter, you need to generate the password hash:

  1. Download the following file:
     oci-crypto-common-1.0.0-SNAPSHOT.jar
  2. Open a command prompt and run the following command:
     java -jar oci-crypto-common-1.0.0-SNAPSHOT.jar pbkdf2_stretch_1000 <password-in-plain-text>

     where <password-in-plain-text> is a password of your choosing.

     You must have Java installed on your computer before running this command.

  3. Record the generated password hash.
  4. Include the generated password hash as the value for the security-master-user-password-hash parameter.
     Use single quotes around the password. For example:

     oci opensearch cluster update ... --security-master-user-name MyUser --security-master-user-password-hash 'pbkdf2_...MNUT5No='

• Run the UpdateOpensearchCluster operation to update a cluster.
