Class ShaPasswordEncoder

java.lang.Object
  org.springframework.security.authentication.encoding.BasePasswordEncoder
      org.springframework.security.authentication.encoding.BaseDigestPasswordEncoder
          org.springframework.security.authentication.encoding.MessageDigestPasswordEncoder
              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>
 

Constructor Summary

ShaPasswordEncoder()
Initializes the ShaPasswordEncoder for SHA-1 strength

ShaPasswordEncoder(int strength)
Initialize the ShaPasswordEncoder with a given SHA stength as supported by the JVM EX: ShaPasswordEncoder encoder = new ShaPasswordEncoder(256); initializes with SHA-256
