Class DBScannerConvertEncryption

java.lang.Object

overit.geocall.basic.bl.encryption.DBScannerConvertEncryption

All Implemented Interfaces:

DBScanner

public class DBScannerConvertEncryption
extends Object
implements DBScanner

This scanner allows to convert the encryption of values storage in the database. It converts only the values inside the columns specified in the input of the constructor. It uses the decryptKey to decrypt value and encryptKey to encrypt value. The two keys can be empty to manage the value in clear, but they must not be null. If there is an error with one value, all the conversions will be rollback and a SQLException will be thrown. It uses the ResultSet to looping on the table, so it doesn't load in memory all rows of the table.
