Throw expection when using setKey on Win98

[jh_Zzz]

Hi There, I met a problem on win98 when try to use setKey, the encrypt arithmetic is KEY_3DES_192, the key is a 24 chanracters string.   Trace into the function, found it was caused by the CryptEncrypt function return NTE_BAD_KEY. The same code work normally on windows 2000 and windows XP. I am using win98 se, IE version is 5.0. How to make the code also can work on win98? Thanks for your great help Jack
