TYPO3 Core

• create a form to record a new fe_user
• use the SaveToDatabase finisher to save data in table fe_users

    options:
      table: fe_users
      mode: create
      databaseColumnMappings:
        crdate:
          value: '{__currentTimestamp}'
        tstamp:
          value: '{__currentTimestamp}'
        pid:
          value: 1
      elements:
        username:
          mapOnDatabaseColumn: username
        password:
          mapOnDatabaseColumn: password
    identifier: SaveToDatabase

There is no option to encode the password which is then recorded in clear in the database.
A feature is missing here to encode password.
