what are you doing to get the XOR key?

[ISHANT]

There is an encrypted Value 

Like example  i get two result in encrypt search -

1253738377 (encrypt)

890    (Original coin value)

i clicked on encrypted coz whenever i edit 890 it comes back to original again.

So try to find xor key and clicked on encrypt value.clicked down and clicked on xor=??? Option, entered original coin value then clicked ok then the value pop up which i copied as xor key then i again edit encrypt value puted value as i want like 999999 and choosed cor key which i copied but still it's not exact it is much different as i edited.
