Class PasswordEncoder

Object

org.jasypt.acegisecurity.PasswordEncoder

All Implemented Interfaces:

org.acegisecurity.providers.encoding.PasswordEncoder

Deprecated.

Deprecated in 1.9.3. This class will be removed in 2.0.0.

public final class PasswordEncoder
extends Object
implements org.acegisecurity.providers.encoding.PasswordEncoder

This class implements the Spring Security (ACEGI) org.acegisecurity.providers.encoding.PasswordEncoder interface, allowing Spring Security-enabled applications to use JASYPT for password encryption.

Objects of this class will internally hold either an object of type org.jasypt.util.password.PasswordEncryptor or an object of type org.jasypt.digest.StringDigester (only one of them), which should be set by respectively calling setPasswordEncryptor(PasswordEncryptor) or setStringDigester(StringDigester) after creation. If neither a PasswordEncryptor nor a StringDigester are set, a new org.jasypt.util.password.BasicPasswordEncryptor object is created and internally used.

Important: This implementation ignores any salt provided through the interface methods, as the internal Jasypt PasswordEncryptor or StringDigester objects normally use a random one. This means that salt can be safely passed as null.

Usage with a PasswordEncryptor

This class can be used like this from your Spring XML resource files:

  ...
  <!-- Your application may use the PasswordEncryptor in several places, --> 
  <!-- like for example at new user sign-up.                             --> 
  <bean id="jasyptPasswordEncryptor" class="org.jasypt.util.password.StrongPasswordEncryptor" />
  ...
  ...
  <!-- This Spring Security-friendly PasswordEncoder implementation will -->
  <!-- wrap the PasswordEncryptor instance so that it can be used from   -->
  <!-- the security framework.                                           -->
  <bean id="passwordEncoder" class="org.jasypt.spring.security.PasswordEncoder">
    <property name="passwordEncryptor">
      <ref bean="jasyptPasswordEncryptor" />
    </property>
  </bean>
  ...
  ...
  <!-- Your DaoAuthenticationProvider will then use it like with any     -->
  <!-- other implementation of the PasswordEncoder interface.            -->
  <bean id="daoAuthenticationProvider" class="org.acegisecurity.providers.dao.DaoAuthenticationProvider">
      <property name="userDetailsService" ref="userDetailsService"/>
      <property name="passwordEncoder">
        <ref bean="passwordEncoder" />
      </property>
  </bean>
  ...
 

Usage with a StringDigester

This class can be used like this from your Spring XML resource files:

  ...
  <!-- Your application may use the StringDigester in several places,    --> 
  <!-- like for example at new user sign-up.                             --> 
  <bean id="jasyptStringDigester" class="org.jasypt.digest.StandardStringDigester" >
    <property name="algorithm" value="SHA-1" />
    <property name="iterations" value="100000" />
  </bean>
  ...
  ...
  <!-- This Spring Security-friendly PasswordEncoder implementation will -->
  <!-- wrap the StringDigester instance so that it can be used from      -->
  <!-- the security framework.                                           -->
  <bean id="passwordEncoder" class="org.jasypt.spring.security.PasswordEncoder">
    <property name="stringDigester">
      <ref bean="jasyptStringDigester" />
    </property>
  </bean>
  ...
  ...
  <!-- Your DaoAuthenticationProvider will then use it like with any     -->
  <!-- other implementation of the PasswordEncoder interface.            -->
  <bean id="daoAuthenticationProvider" class="org.acegisecurity.providers.dao.DaoAuthenticationProvider">
      <property name="userDetailsService" ref="userDetailsService"/>
      <property name="passwordEncoder">
        <ref bean="passwordEncoder" />
      </property>
  </bean>

Constructor Detail

PasswordEncoder

public PasswordEncoder()

Deprecated.

Creates a new instance of PasswordEncoder

Method Detail

setPasswordEncryptor

public void setPasswordEncryptor(org.jasypt.util.password.PasswordEncryptor passwordEncryptor)

Deprecated.

Sets a password encryptor to be used. Only one of setPasswordEncryptor or setStringDigester should be called. If both are, the last call will define which method will be used.

Parameters:

passwordEncryptor - the password encryptor instance to be used.

setStringDigester

public void setStringDigester(org.jasypt.digest.StringDigester stringDigester)

Deprecated.

Sets a string digester to be used. Only one of setPasswordEncryptor or setStringDigester should be called. If both are, the last call will define which method will be used.

Parameters:

stringDigester - the string digester instance to be used.

encodePassword

public String encodePassword(String rawPass,
                             Object salt)

Deprecated.

Encodes a password. This implementation completely ignores salt, as jasypt's PasswordEncryptor and StringDigester normally use a random one. Thus, it can be safely passed as null.

Specified by:

encodePassword in interface org.acegisecurity.providers.encoding.PasswordEncoder

Parameters:

rawPass - The password to be encoded.

salt - The salt, which will be ignored. It can be null.

isPasswordValid

public boolean isPasswordValid(String encPass,
                               String rawPass,
                               Object salt)

Deprecated.

Checks a password's validity. This implementation completely ignores salt, as jasypt's PasswordEncryptor and StringDigester normally use a random one. Thus, it can be safely passed as null.

Specified by:

isPasswordValid in interface org.acegisecurity.providers.encoding.PasswordEncoder

Parameters:

encPass - The encrypted password (digest) against which to check.

rawPass - The password to be checked.

salt - The salt, which will be ignored. It can be null.
