      extended by org.springframework.security.authentication.encoding.BaseDigestPasswordEncoder
          extended by org.springframework.security.authentication.encoding.MessageDigestPasswordEncoder
              extended by org.springframework.security.authentication.encoding.ShaPasswordEncoder
All Implemented Interfaces:
PasswordEncoder

public class ShaPasswordEncoder
extends MessageDigestPasswordEncoder

SHA implementation of PasswordEncoder.

If a null password is presented, it will be treated as an empty String ("") password.

As SHA is a one-way hash, the salt can contain any characters. The default strength for the SHA encoding is SHA-1. If you wish to use higher strengths use the argumented constructor. ShaPasswordEncoder(int strength)

The applicationContext example...

 <bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.ShaPasswordEncoder">
     <constructor-arg value="256"/>
 </bean>
