Starting Edge Flow Manager with encrypted properties

Learn how to start up Edge Flow Manager after you encrypt a single sensitive property or multiple sensitive properties.

After you set the encrypted properties in the efm.properties file described in Encryption of a single property or Encryption of multiple properties section, you need to provide your secret key to Edge Flow Manager at startup. There are two ways to provide the secret key; directly through a property or through a file:
  • You can set the secret key directly through a property in the following ways:

    • As a command line argument: ./bin/efm.sh --efm.property.encryptor.password=secretKey

    • As a Java system property: -Defm.property.encryptor.password=secretKey

    • As an Operating System environment variable: export EFM_PROPERTY_ENCRYPTOR_PASSWORD=secretKey

    • As a key value pair in the efm.properties file: efm.property.encryptor.password=secretKey

  • You can set the secret key through a file in the following way:

    Provide the path to the secret key file in the efm.property.encryptor.passwordFile property:
    efm.property.encryptor.passwordFile=<path-to-file>
