[SOLVED] Verify LDAP user password with SSHA-512 hash method

Verify LDAP user password with SSHA-512 hash method

I am using OpenLDAP to store user information. User entry is an inetOrgPerson object. I use Apache Directory Studio to add userPassword with SSHA-512 hash method.

How can I verify input user password with the password stored in LDAP in my Java application?

Solution

I found my answer: http://gurolerdogan.blogspot.com/2010/03/ssha-encryption-with-java.html

SSHA ssha = new SSHA("SHA-512");
String sshaStr = ssha.createDigest("randomString", "mypwd");
//{SSHA}5QxZCiM/zcn0/upHX2uw6ICbgE+PLa9sJz/UpfMAMe1isyxuv+NeW4k4GjRDoTQHnB5QjCKCydJJjUQnT3DEEXJhbmRvbVN0cmluZw==
return sshaStr;

Replace {SSHA} with {SSHA-512} you will have a SSHA-512 password to store in OpenLDAP. It's useful when you create new user or update user password.

You can improve the source code, for example replace sun.misc.BASE64Encoder with org.apache.commons.codec.binary.Base64.
