Constructor Detail

• SecureDatabaseStore

  SecureDatabaseStore(Context context, String databaseName, Integer databaseVersion, CreateDatabaseCallback callback)

Method Detail

• getAutoEncryptionKeyAlias

   final String getAutoEncryptionKeyAlias()

• isOpen

   final Boolean isOpen()

  Checks if the database exists and has been opened, that is, .open )} has been called and .close has not been called.

• isInTransaction

   final Boolean isInTransaction()

  Checks if a transaction is in progress.

• getDatabase

   final SQLiteDatabase getDatabase()

  Returns the underlying net.sqlcipher.database.SQLiteDatabase instance assuming .SecureDatabaseStore and .open have been called.

• getDatabaseName

   final String getDatabaseName()

• open

   final Unit open(ByteArray encryptionKey)

  Opens the encrypted database with the encryption key.

  You must open the store before you can interact with it. The store can fail to open if the encryption key is incorrect. When the store is opened for the first time, the provided key is used to encrypt the database.

  Parameters:

  encryptionKey - the key to encrypt the store.

• changeEncryptionKey

   final Unit changeEncryptionKey(ByteArray newEncryptionKey)

  Changes the encryption key of the database.

  Database should have been opened with the old encryption key.

  Parameters:

  newEncryptionKey - new encryption key.

• deleteAutoEncryptionKey

   final Boolean deleteAutoEncryptionKey()

• existsAutoEncryptionKey

   final Boolean existsAutoEncryptionKey()

• deleteStore

   final Unit deleteStore(Context context)

  Deletes the database file. Note that this instance is no longer usable after the call, any operation performed on the instance will get FileMissingException.

  Parameters:

  context - Android application context

• close

   final Unit close()

  Closes the database. Note that once the database is closed, no operations are allowed.

• executeUpdate

   final Unit executeUpdate(String sql)

  <pre>`static final String TABLE_NAME = "account_user"; static final String COLUMN_EMAIL = "email"; static final String COLUMN_FULL_NAME = "fullName"; static final String COLUMN_ACCOUNT_NAME = "accountName"; // Fills each column with value. ContentValues cv = new ContentValues(); cv.put(COLUMN_EMAIL, "john.smith@mycompany.com"); cv.put(COLUMN_FULL_NAME, "John Smith"); cv.put(COLUMN_ACCOUNT_NAME, "JSmith032"); // databaseStore was defined, instantiated and opened already. databaseStore.executeInsert(TABLE_NAME, cv); ` * </pre> *

  Parameters:

  tableName - table name

  values - a ContentValues object that contains column names and the associated values

• executeStatements

   final Unit executeStatements(String sqlStatements)

  Parameters:

  sqlStatements - a vararg (array) of SQL statements

   final SecureDatabaseResultSet executeQuery(String sql, String values)

  Executes a SELECT statement that contains parameters ('?').

  sql - a SELECT statement

  values - one or more String values to match the '?

• executeQuery

   final SecureDatabaseResultSet executeQuery(String sql)
