DelegatingPasswordEncoder
which supports
password upgrades. There are no plans to remove this support. It is deprecated to indicate
that this is a legacy implementation and using it is considered insecure.@Deprecated public class Md4PasswordEncoder extends java.lang.Object implements PasswordEncoder
PasswordEncoder
is provided for legacy purposes only and is not considered secure.
Encodes passwords using MD4. The general format of the password is:
s = salt == null ? "" : "{" + salt + "}" s + md4(password + s)Such that "salt" is the salt, md4 is the digest method, and password is the actual password. For example with a password of "password", and a salt of "thisissalt":
String s = salt == null ? "" : "{" + salt + "}"; s + md4(password + s) "{thisissalt}" + md4(password + "{thisissalt}") "{thisissalt}6cc7924dad12ade79dfb99e424f25260"If the salt does not exist, then omit "{salt}" like this:
md4(password)If the salt is an empty String, then only use "{}" like this:
"{}" + md4(password + "{}")The format is intended to work with the Md4PasswordEncoder that was found in the Spring Security core module. However, the passwords will need to be migrated to include any salt with the password since this API provides Salt internally vs making it the responsibility of the user. To migrate passwords from the SaltSource use the following:
String salt = saltSource.getSalt(user); String s = salt == null ? null : "{" + salt + "}"; String migratedPassword = s + user.getPassword();
