Class EncryptionReplacer

java.lang.Object

com.hazelcast.config.replacer.AbstractPbeReplacer

com.hazelcast.config.replacer.EncryptionReplacer

All Implemented Interfaces:

ConfigReplacer

public class EncryptionReplacer
extends AbstractPbeReplacer

This class is an example ConfigReplacer implementation which decrypts encrypted values.

The main(String...) method is provided to generate the encrypted variables.

This class extends AbstractPbeReplacer where the main encryption logic is located. This class implements getPassword() method and depending on configuration allows to use a password file and/or user properties (name and HOME) and/or network interface properties (MAC address).
