I have a database of hashed Wordpress passwords. I am trying to check a user's password against the database stored password, but the hashes aren't correct. I am using this github code with some logging in isMatch()
. Any ideas why these passwords don't match? the plain text password is alberta10
public boolean isMatch(String password, String storedHash) {
// The first 12 digits of the hash is used to modify the encryption.
String setting = storedHash.substring(0, 12);
logger.log(Level.INFO, "----Hashed pwd from db is: "+storedHash);
logger.log(Level.INFO, "----Hashed pwd using php-pass: "+encrypt(password, setting));
return storedHash.equals(encrypt(password, setting));
}
Here is my authenticate()
method
private void authenticate(String username, String password) throws Exception {
// Throw an Exception if the credentials are invalid
PasswordHasher pwdHasher=new PasswordHasher();
_logger.log(Level.INFO, "----Authenticating user: "+username);
try{
Connection conn=authenticationBiz.connWordpressDB();
String query = "SELECT * FROM wp_users WHERE user_login = ?";
PreparedStatement preparedStmt = conn.prepareStatement(query);
preparedStmt.setString(1, username);
ResultSet rs=preparedStmt.executeQuery();
rs.next();//get first result
_logger.log(Level.INFO, "----Hashed pwd from db is: "+rs.getString("user_pass"));
if(pwdHasher.isMatch(password,rs.getString("user_pass")))
return;
}
catch(Exception e){
_logger.log(Level.INFO, "----Exception in Authenticating user: "+e);
throw e;
}
throw new Exception();
}
Heres the log output:
----Hashed pwd from db is: $P$BeatnTVG2/U8KZwpaWbPUF4yghHEKf.
17:21:40,997 INFO [com.mollom.phpass] (default task-37) ----Hashed pwd from db is: $P$BeatnTVG2/U8KZwpaWbPUF4yghHEKf.
----Hashed pwd using php-pass: $P$BeatnTVG2etvrth3rlCUdiNRm93PO9xZjXNr1f5s8izUZFfIq70V

Turns out I was using a Github project that didnt match the initial criteria used to generate the hashes. I discovered: https://github.com/Wolf480pl/PHPass which worked perfectly

Wordpress uses 8 hash iterations, the git hub cod you've linked uses 15 iterations, maybe you can't just try to reduce the number of hash iterations defined in the constant HASH_ITERATIONS.
