Solved using static analysis with Ghidra by locating the main function, examining the decompiled code, and identifying the hardcoded hexadecimal comparisons (0x21 and 0x66) that correspond to the required inputs. |

I entered a username that was 24 characters long. I ran the program with special my key, which was generated based on a 62-character alphabet, and I saw that the key was valid. |
