[Click to reveal]The password is just 'password', but in the program it is stored as a hash :(5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8)

[Click to reveal]After reversing the algorithm in Ghidra, I confirmed this crackme has no valid solution.
The issue comes from instruction 04 which does: rax_6 += (rax_6 ^ 0x12345678) >> 2
This operation is non-linear and cannot be reversed, making the target value 0x6F3A9B21 unreachable regardless of the password entered.

| Challenge #5 |
[Click to reveal]The program converts your input into binary (8 bits per character) then compares it with a hardcoded binary string stored in data_140004000.
The trick was just to decode that binary string directly — no need to run the program.
