Description

The dataStore.encryptionStatus( ) command returns an object providing the encryption status for the current data file (i.e., the data file of the ds datastore). The status for each table is also provided.

Note: Use the Data file encryption status command to determine the encryption status of any other data file.

Returned value

The returned object contains the following properties:

Property			Type	Description
isEncrypted			Boolean	True if the data file is encrypted
keyProvided			Boolean	True if the encryption key matching the encrypted data file is provided(*).
tables			Object	Object containing as many properties as there are encryptable or encrypted tables.
	<table name>		Object	Encryptable or Encrypted table
		name	Text	Name of the table
		num	Number	Table number
		isEncryptable	Boolean	True if the table is declared encryptable in the structure file
		isEncrypted	Boolean	True if the records of the table are encrypted in the data file

(*) The encryption key can be provided:

with the dataStore.provideDataKey( ) command,
on a connected device before opening the datastore,
with the Discover data key command.

Example

You want to know the number of encrypted tables in the current data file:

 C_OBJECT($status)

 

 $status:=dataStore.encryptionStatus()

 

 If($status.isEncrypted) //the database is encrypted

    C_LONGINT($vcount)

    C_TEXT($tabName)

    For each($tabName;$status.tables)

       If($status.tables[$tabName].isEncrypted)

          $vcount:=$vcount+1

       End if

    End for each

    ALERT(String($vcount)+" encrypted table(s) in this datastore.")

 Else

    ALERT("This database is not encrypted.")

 End if
