All known Subclasses:   org.acegisecurity.providers.encoding.ShaPasswordEncoder,  org.acegisecurity.providers.encoding.Md5PasswordEncoder,
MessageDigestPasswordEncoder
public class MessageDigestPasswordEncoder extends BaseDigestPasswordEncoder (Code)
Base for digest password encoders.

This class can be used stand-alone, or one of the subclasses can be used for compatiblity and convenience. When using this class directly you must specify a Message Digest Algorithm to use as a constructor arg

The encoded password hash is normally returned as Hex (32 char) version of the hash bytes. Setting the encodeHashAsBase64 property to true will cause the encoded pass to be returned as Base64 text, which will consume 24 characters. See BaseDigestPasswordEncoder.setEncodeHashAsBase64(boolean)

This PasswordEncoder can be used directly as in the following example:

 <bean id="passwordEncoder" class="org.acegisecurity.providers.encoding.MessageDigestPasswordEncoder">
 <constructor-arg value="MD5"/>
 </bean>

Constructor Detail
MessageDigestPasswordEncoder
public MessageDigestPasswordEncoder(String algorithm)(Code)
The digest algorithm to use Supports the named Message Digest Algorithms in the Java environment.
Parameters:
  algorithm -



MessageDigestPasswordEncoder
public MessageDigestPasswordEncoder(String algorithm, boolean encodeHashAsBase64) throws IllegalArgumentException(Code)
Convenience constructor for specifying the algorithm and whether or not to enable base64 encoding
Parameters:
  algorithm -
Parameters:
  encodeHashAsBase64 -
throws:
  IllegalArgumentException - if an unknown




Method Detail
encodePassword
public String encodePassword(String rawPass, Object salt)(Code)
Encodes the rawPass using a MessageDigest. If a salt is specified it will be merged with the password before encoding.
Parameters:
  rawPass - The plain text password
Parameters:
  salt - The salt to sprinkle Hex string of password digest (or base64 encoded string if encodeHashAsBase64 is enabled.



getAlgorithm
public String getAlgorithm()(Code)



getMessageDigest
final protected MessageDigest getMessageDigest() throws IllegalArgumentException(Code)
Get a MessageDigest instance for the given algorithm. Throws an IllegalArgumentException if algorithm is unknown MessageDigest instance
throws:
  IllegalArgumentException - if NoSuchAlgorithmException is thrown



isPasswordValid
public boolean isPasswordValid(String encPass, String rawPass, Object salt)(Code)
Takes a previously encoded password and compares it with a rawpassword after mixing in the salt and encoding that value
Parameters:
  encPass - previously encoded password
Parameters:
  rawPass - plain text password
Parameters:
  salt - salt to mix into password true or false
