Class ReEncryptor

java.lang.Object

org.alfresco.encryption.ReEncryptor

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class ReEncryptor
extends Object
implements org.springframework.context.ApplicationContextAware

Re-encrypts encryptable repository properties using a new set of encryption keys. Decrypts the repository properties using the default encryptor, falling back to a backup decryptor (using the old encryption keys) if necessary, and then re-encrypts the properties. Can run in one of two ways:

• during bootstrap.
• by using JMX (available only to Enterprise). In this case, the system can stay running while the re-encryption takes place.

Since:

4.0

setTransactionService

public void setTransactionService(TransactionService transactionService)

Set the transaction provider so that each execution can be performed within a transaction

reEncryptProperties

protected void reEncryptProperties(List<NodePropertyEntity> properties,
                                   String lockToken)

bootstrapReEncrypt

public int bootstrapReEncrypt()
                       throws MissingKeyException

Re-encrypt using the configured backup keystore to decrypt and the main keystore to encrypt

Throws:

MissingKeyException

reEncrypt

public int reEncrypt()
              throws MissingKeyException

Re-encrypt by decrypting using the configured keystore and encrypting using a keystore configured using the provided new key store parameters. Called from e.g. JMX. Assumes that the main key store has been already been reloaded. Note: it is the responsibility of the end user to ensure that the underlying keystores have been set up appropriately i.e. the old key store is backed up to the location defined by the property '${dir.keystore}/backup-keystore' and the new key store replaces it. This can be done while the repository is running.

Throws:

MissingKeyException

reEncryptImpl

protected int reEncryptImpl()

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException
