Method Detail

doConfigure

public void doConfigure(Properties parameters,
                        String prefix)

Configures and initializes the encoder using the given Properties.

Specified by:

doConfigure in class AbstractConfigurablePasswordEncoder

Parameters:

parameters - the parameters

prefix - the prefix

doEncode

public String doEncode(CharSequence rawPassword)

Encode the raw password. This should combine a message digest (hash) function with randomly generated salt.

Specified by:

doEncode in class AbstractConfigurablePasswordEncoder

Parameters:

rawPassword - the raw password to encode

Returns:

the encoded password

isMatch

public boolean isMatch(CharSequence rawPassword,
                       String encodedPassword)

Verify the encoded password obtained from storage matches the submitted raw password after it too is encoded. Returns true if the passwords match, false if they do not. The stored password itself is never decoded.

Specified by:

isMatch in class AbstractConfigurablePasswordEncoder

Parameters:

rawPassword - the raw password to encode and match

encodedPassword - the encoded password from storage to compare with

Returns:

true if the raw password, after encoding, matches the encoded password from storage
