1:Search copy/paste to find the registration box location:

2:Back to the registration function:
3:Enter the verification code verification function:

1-1EB27BB9792E62BC13A77708C279D580AF1B16059CA949E53036FB3F0F3

This string should be the private key, the one below

rax = sub_10019c610(&var_30, rbx, r15)

This is where the input string is really judged, follow up to see the implementation

4:Verification algorithm:

Here, we only need to modify the return value:

loc_10019c77d:
mov        al, bl      ; CODE XREF=sub_10019c610+477, sub_10019c610+488, sub_10019c610+714
add        rsp, 0x60
pop        rbx
pop        r14
pop        rbp
ret

Change mov al,bl to mov al,0x1, you don’t even need nop padding
5:After exporting the executable file, any registration code can be activated
