  Hard bug to catch !, i can't reproduce this so will move to divide and conquer, for that we need to separate the decryption from MAC calculation.
  
  Please try this, if you are in the mood to test deeper or you have time, this will show if the MAC is the failed point or not:
  unit Tools.Crypt;
  
  interface
  
  uses
  System.SysUtils, DECUtil, DECHash, DECCipherBase, DECCiphers, DECHashBase,
  ...

  Can you capture/log the exact SQL query when the exception happen ?
  
  I am sorry, can't understand the exception !, is it a fail to find parameter or something, like the there is SQL but broken !?
  
  Anyway, i suspect the use of RawByteString is and as always the root of evil, so i will adjust your code a little to remove this dependency as much as i can.
  
  ps: i asked for specific test vector...

  Here this is the smallest workaround the problem for this case like what OP presented.
  
  the modification are only in DECHashAuthentication.pas
  function ValidAuthHash(HashClass: TDECHashClass): TDECHashAuthenticationClass;
  procedure SetDefaultAuthHashClass(HashClass: TDECHashClass);
  
  implementation
  
  uses
  DECUtil;

  I see this discrepancy in the implementation
  
  // in DECHash.pas
  THashBaseMD4 = class(TDECHashAuthentication)
  THash_SHA0 = class(THashBaseMD4)
  THash_SHA256 = class(THash_SHA0)
  
  // while in DECHashAuthentication.pas
  TDECHashAuthentication = class(TDECHash)

  Yes, it is tricky to add IDECHashAuthentication because the class methods, and to solve this either add the same naming methods in TDECHash, so you can redirect all these methods to the class ones in TDECHashAuthentication, or introduce new global function ValidPasswordHash just like ValidHash that return TDECHashAuthentication.
  
  Both approaches are not ideals, the best or the better is MAY BE...

  ValidFormat is used as generic or general use function that can be used to one hit call, But ValidHash it seems was working in DEC v5 but with all the refactoring and separating code in different specialized units with DEC v6 it did lose the functionality code form TDECHashAuthentication.
  
  I think DEC v6 should add/have an interface (IDECHashAuthentication) to TDECHash like this :
  
  {$IFDEF...

  I looked at the library,
  ValidFormat and ValidHash supposed to be working as factory design, you feed them a class type and will get a class, this implementation to remove the need to hardcode a switch between algorithms.
  
  https://en.wikipedia.org/wiki/Factory_method_pattern
  but with simple function instead of a class.

  Hi,
  
  TurboMagic said will take a look, i hesitated yesterday to write the following:
  
  I can do it even i have never used DEC v5 and have very shallow knowledge with v6, but i believe i can figure it out, BUT i need few things to make sure not wasting my time and yours:
  
  1) the original code, the code was/is working with DEC v5.1, not a modified one.
  2) Three handled/hashed data
  A) a...
