Class SystemWideSaltSource

java.lang.Object

org.springframework.security.authentication.dao.SystemWideSaltSource

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, SaltSource

public class SystemWideSaltSource
extends java.lang.Object
implements SaltSource, org.springframework.beans.factory.InitializingBean

Uses a static system-wide String as the salt.

Does not supply a different salt for each User. This means users sharing the same password will still have the same digested password. Of benefit is the digested passwords will at least be more protected than if stored without any salt.
