reverse

1. break at main, run, and disas:

   gdb . . 0x000055555555527e <+181>: test %eax,%eax 0x0000555555555280 <+183>: jne 0x55555555529c <main+211> . .

   The result of test seems to decide the final jump..

2. Change the value of $eax:

   ```gdb (gdb) b *main+181 Breakpoint 2 at 0x55555555527e (gdb) c Continuing. Enter the password to unlock this file: flag You entered: flag

   Breakpoint 2, 0x000055555555527e in main () (gdb) set $rax=0 (gdb) c Continuing. Password correct, please see flag: picoCTF{3lf_r3v3r5ing_succe55ful_7851ef7d} ```
