New Post: Problem with verification of pin block generated with ZPK

i also tried with format 01 as follow
gen pin block =
PINBlock1 = ("02" + PIN + "FFFFFFFFFF");
PINBlock2 = "0000" + AccountNumber ;

PIN BLOCK = XORHexS (PINBlock1, PINBlock2);

Cipher PINBLOCK = TripleDESEncrypt (ZPKHex, PINBlock);

but always same problem EC........ return ED20 ( pinblock does not contain valid value )

Thanks for your assistance.
