It's written in pure assembler. Not packed or protected in any way. You can check it's not virus/trojan. Either throw out Defender or better reverse it and tell what malicious task it performs. |

I'm glad You liked it. Yes last part is quite simple math (althrough all pieces are simple once You know what they do). Waiting for solution once You put all pieces together. |

"OUPWO" - testing - if site doesn't show then sixth char is 0x3E |

OUPWO - type this as name with any serial and crackme solved. |

Maybe some harder math equations? If You want to implement CRC32 there is plenty of vulnerabilities that can be used with it. And making serial more name dependent will make it harder. If in this one serial would depend more on name it would make writing keygen quite difficult. |

@Tester009 Here is my keygen - serial that works for any name.
Name - any (2 to 40 chars to satisfy keygenme condition)
Serial - 007007D8B5C3R2CC0DED0C59B
If it displays bad it's 0x07. |

@Tester009 Well I uploaded my solution. It was nice keygenme. I was a bit disapointed with name dependency. If it was more name dependent it would be more challenging. I most liked the part 5 serial check. This took me most of time. |

Made one small mistake with range and can tell that there are two possible separators. Here is second combo:
ToMKoL
1131106FF1C3R2C51BCD07B19
If it displays wrong it's 0x06. |

Nice one. I wouldn't rate it as 4. At most 3 but really interesting keygenme. Here is mine combo:
ToMKoL
¶11311¶06FF1¶C3R2C¶51BCD¶07B19¶
And aswering to Xor0 question separator has only one solution that pass check. |
