KB-30892: Can Centrify Password Synchronization Be Configured to use Stronger Encryptions than the Default DES?

Authentication Service ,  

1 April,20 at 10:54 PM

Question:
  
By default, the Centrify Password Synchronization utility will encrypt the password using the DES encryption algorithm.  Can password sync be configured to use stronger and newer algorithms?

Answer:
  
Starting with Centrify Server Suite release 2017.3, the password synchronization can be configured to use any one of these encrypt ions:  DES, MD5, SHA256, or SHA512.

To configure a different encryption, make a new key in the registry of EVERY domain controller.  If the edit is not done for every DC, there will be random, unexpected failures in password hash.

 
HKLM\SOFTWARE\Centrify
DWORD: EncryptionType
Values:
  0 = DES
  1 = MD5
  2 = SHA256
  3 = SHA512
  
User-added image
    
The next time the user changes his password, the new encryption algorithm will be used to create the password hash.
  
  

Note: The Centrify Agent for Linux (adclient) does not use the passwordhash.  It simply caches the value directly from Active Directory.  Any application that uses the passwordhash must be able to handle the same encryption type.
