You need to use PHP to convert the same encryption result to a hexadecimal format.

That is, if there are 8 bits, such as 00000000
The encrypted data is converted to a hexadecimal value, which is 16 bits.

They provide a software I encrypt 12345678
First, convert 12345678 to a hexadecimal string using bin2hex and the result is 3132333435363738.
The encrypted result is B2A85CF088D9FF03.



Now we need PHP to implement the same encryption result as it! I tried it many times but I couldn't match it. please paste the code
With the JAVA encryption code:

Thank you!

Occupied by yourself on the first floor, online and so on! If you have any ideas, you are welcome.

I have done it myself. who is the fuck?
