| fourexps hard crackme | @fourexp you uploaded a debug build of the crackmes, which would not properly run on other people's computer. This should not have been accepted. I recommend you to upload a new one, and then I will delete this one | 2026-08-01 11:40 |
| SlimKeyGen | @deleted_user please try to be respectful to challenge authors. | 2026-07-26 01:51 |
| SlimKeyGen | @Biglsim04 no he actually did not -- it is funny, the decompiler emitted wrong code which then lead AI to give a totally wrong solution (AI believes it is correct as long as the last part of the key is 0x1) | 2026-07-25 15:36 |
| SlimKeyGen | @deleted_user your solution was wrong because it is just incorrect -- it did not produce valid keys. I think the reason for that is 1) that the decompilers screwed up and produced incorrect output, which is picked up by AI to produce a wrong solution; 2) you did not test it against the real crackme -- if you run it you will see it is wrong | 2026-07-25 15:35 |
| SlimKeyGen | @deleted_user I approved your writeup, but I think it is wrong upon closer inspection, so I have deleted it. Please feel free to submit a new one if you have something new! | 2026-07-25 00:42 |
| 67 | @harvest I will try to do so soon! I used AI to solve it and the writeup it does is not very informative. I want to polish it a bit before submitting | 2026-07-07 16:18 |
| 67 | Very nice one! I will post writeup shortly | 2026-06-29 15:46 |

| crackme3 by vohligh | This crackme had been reviewed when it was originally approved and is likely safe.

| Derive64 v1.0 | @yanggao178 it is "crackmes.one", see https://crackmes.one/faq#password-protected | 2026-01-03 03:14 |
| Matryoshka | This is really a nice interesting challenge, thx! | 2025-10-30 03:37 |
| First Program | This is not a malware. Some contributing factors for the false positive are 1) The file is an .exe compiled with GCC, 2) it carries large resources in the .rsrc section, but mainly it is just the pacman icon | 2025-04-13 05:21 |
| Quantum realm | This is a test comment | 2025-04-06 07:08 |
| Level Two crackme password | Hi @dev0, yeah for the very same reason I think the challenge is busted and cannot be solved. I have tried to contact the author on this but have not been successful yet | 2024-09-26 18:01 |
| KeygenMe_SWD | Hi @SirWardrake, dnSpy appears to be unable to show the code (or even recognize the file as .NET) because of the way you compiled it (which might be intentional or unintentional). If you use Detect it Easy to check the file, you can find there is an overlay PE file at offset 0x25000. You can dump this file and load it with dnSpy, and see all of you code in it. | 2024-03-15 07:46 |
| ExotiCTF | Nice swift crackme! I am giving a level 2.5 difficulty given the obvious shortcut | 2024-02-26 08:14 |
| heaven.exe | Same idea as https://crackmes.one/crackme/63b15b5333c5d43ab4ecf226 | 2023-09-22 13:22 |
| GPTCrackMe | I had a look at it, and got a basic understanding of the algorithm, but I did not spend the time to actually solve it. This is a cool one, btw | 2023-09-22 04:55 |
| keygenme | @f1ref1st, the intention is to understand the algorithm and write a keygen, otherwise the challenge would be trivial | 2023-07-05 14:12 |
| CrackMe #1 | There seems to be a bug in this crackme, so that on certain Windows versions, running the crackme will get you nothing. However, it is still solvable if you analyze/debug it and see what the maker's intention is. And as timotei_ said, the MD5 of the key is 7813d1590d28a7dd372ad54b5d29d033 | 2023-05-30 12:34 |

| C4n_u_K3yG3n? | Looks interesting and approachable, nice one, thx! | 2022-11-24 13:49 |
| World Useless CrackMe | Thx for the crackme! However, I think it has some problems: 1. the crackme is not asking for an input, so the check will always fail. 2. It seems to me, that if it does ask for an input, any input that has length 6 will pass the check. I am not 100% sure about it because I just glanced the code and did not analyze it in detail. | 2022-08-21 03:48 |
| keygen-me | This is a nice algorithm crackme. I followed the key generation in the debugger, and find it is interesting. Thx! | 2022-05-31 09:25 |
| funcoleto | Nice addition to the crackme collection! The algorithm is not hard. And it is fun reversing swift code. | 2022-05-31 08:45 |

| crackme_1_by_huskyhusky by huskyhusky | Interesting VM challenge! Although I have had tooooo many of VM challenges and no longer get excited by them easily, this one is still nice and worth trying out. | 2021-05-02 14:19 |
| pcme0 by pancake | This one comes with some interesting anti-debugging and obfuscation, but the actual algorithm is too simple, so giving a 3.0 difficulty and 4.0 quality rating. | 2021-05-02 13:43 |
| insane password checker | Thanks for the submission! However, I do not really see how it is level 6. Probably something like a level 2-3. | 2021-04-13 13:47 |
| Basic Password Checker | [Click to reveal]I personally do not think it is a malware. I have reversed it and found nothing suspicious. VirusTotal can have false positives, and the network and registry activity reported by it is not always accurate. But I am still open to other opinions. Feel free to DM me on the crackmes.one Discord server. | 2021-04-09 04:50 |
| ORiGiN KeygenMe | This is a great and difficult challenge. It has sufficient and complex transformations for a reverser to break. I reversed most part of it and become lazy to piece together every part. It becomes a little bit dull in the end (no offense). The level is probably 4. Thanks for the challenge! | 2021-01-10 12:58 |
| trinity | This one offers a great chance to learn several fpu instructions that are not often used. The level is probably 3 though. Thx! | 2021-01-10 12:56 |
| DarkMoon | Hi @omrifainaro, thanks for the report! Could you please tell me why you think its a virus? | 2021-01-05 01:35 |
| NES crackme #1 | Nice challenge! The algorithm is simple, but finding it in the first place is the real challenge | 2020-12-24 11:36 |
| Crack me | I am very doubtful that this is solvable unless we brute-force the sha256 or DES, any hint on it? | 2020-12-12 06:53 |
| goCrackMe | not bad! | 2020-12-06 02:45 |
| c++ crackme | I think this is probably a level 2. The compiler is unfamiliar -- so it might be a little bit challenging in the beginning, but soon it all sorts out | 2020-12-06 02:31 |
| Crackxx | This one uses WinLincence, which is fine -- but not a very good idea -- to use commercial packers/protectors to make a crackme | 2020-12-06 02:01 |
| Look Closer | This one is interesting! It uses a small and novel obfuscation trick to confuse the reverser. | 2020-12-05 16:07 |
| ReverseMe3 | This is a GREAT challenge! I will make a writeup for it | 2020-11-21 04:23 |
| Personal Safe | interesting one. Though I think r13 needs to be zeroed on entry | 2020-11-19 13:18 |
| 75627548 | This is nice, but it is probably better rated as level one | 2020-10-26 06:52 |
| Lenrev | Rust again! thx! | 2020-10-14 05:56 |
| Date of Birth | @BitFriends There should be many dates that pass the check. Though they should all exploit the same flaw. It is nice that you found one. Congrats! | 2020-10-14 05:42 |
| Crack The Door | a good practice for string operations and division by multiplication | 2020-08-12 09:36 |
| Crack_5 | nice! not hard to find all possible solutions | 2020-08-08 08:02 |
| Maths | This one is super nice! I like the algorithm. Finding the second solution is harder but also more interesting. | 2020-08-08 07:57 |
| Keygenme - Muldimalph | nice algorithm! not hard, but a good practice for floating point instructions | 2020-08-08 03:37 |
| no strings attached | Interesting one! The real challenge is to find the main() function | 2020-08-08 01:48 |
| bubbly | Hi BitFriends! If you are talking about the disassembly at line 0x6dc then yes, it is comparing two addresses. But you have to understand why it is doing this, or, what is the criteria it can pass. If you want a faster discussion, you may wish to reach me on discord. | 2020-07-27 02:14 |
| bubbly | @BitFriends: Nope, I do not think so. It is not comparing addresses | 2020-07-24 05:58 |
| iDOS | btw, if its convenient for you, pls join the crackmes.one discord server (shown on the front page) so we can communicate faster (if you would like) ^_^ | 2020-07-14 05:33 |
| iDOS | Its definitely worth trying to come up with a concrete collision method and a working exploit, though I am not sure how motivated I am to do it. Anyway, thx for the crakcme! If I get back on this I will let you know. | 2020-07-14 05:27 |
| iDOS | I do not have a working collision method but I remember seeing some materials on this topic so I assume it would not be too hard to make it work. I am not sure whether gcc source code is related. Because I think the relevant implementation is in glibc C++ runtime implementation. | 2020-07-14 05:26 |
| iDOS | Ohhh, my bad, yeah, it is still waiting for input. The problem is if I input too many chars at a time, maybe its truncated. I will get back to this later | 2020-07-14 02:22 |
| iDOS | My solution is probably wrong bc I did not trigger the collision in the correct way. But since I get the idea I will skip for this. Nice challenge and thx! | 2020-07-14 02:16 |
| iDOS | I got the idea is to create a lot of collisions to DOS the unordered_map. But yeah, the program itself is a bit slow that I give 10k numbers to it and it never finishes. No matter its a random list or 10k 1s. by the way, if the program can print something when it reads all the input, it would be easier to see whether the solution is correct or wrong. That said, I do not think the program is still waiting for inputs. It just hangs for 10k inputs. Originally, I think it should handle 10k random numbers pretty well, so when I send 10k 1s and it hangs, I thought I solved it. | 2020-07-14 02:14 |
| simple overflow | simple and interesting. Though it relies on certain property of malloc which is not always true | 2020-07-14 02:06 |
| whoami | `Stay polite` | 2020-07-13 16:13 |
| timotei crackme#4 | There are several ways to solve it, thx! | 2020-07-13 16:09 |
| timotei crackme#3 | nice one, thx! | 2020-07-13 16:09 |
| iDOS | This one is nice! Just give it a really long sequence that has the same numbers and it will hang. | 2020-07-12 13:48 |
| Quick Crypto, 18k | nice challenge, andrewl! | 2020-07-12 13:01 |
| Pass verification | thx for the challenge. I am afraid that this is probably level 1 | 2020-07-12 10:21 |
| Sh4ll11 | hardware breakpoint (hbreak) is useful for this! | 2020-07-07 15:19 |
| Sh4ll11 | Reversed it and found the point list! Flag: eea5fcb2b7f9327e9e375e18f1cd31d01ef3e48a. I did not really plot the points, do they form an image? | 2020-07-07 15:18 |
| Sh4ll4 | patch the strcmp() at 0xbd7 to puts() and get the flag like a pro! | 2020-07-07 10:55 |
| Sh4ll8 | I used gcore to dump the program before I input anything. To increase the difficulty, try to do anti-debugging BEFORE asking for any input (but also after unpacking itself). Also, as pointed out by @s4r, there is a small glitch of the program so that a partial password also passes the validation. | 2020-07-07 06:46 |
| Sh4ll9 | Unfortunately I think this one involves too many guesses so I do not really like it | 2020-07-07 06:16 |
| EXTORY | interesting one! The anti-debugging are not very helpful since the crackme itself can be solved statically. | 2020-07-05 00:49 |
| ShAPK1 | A nice one for beginners! | 2020-06-18 04:41 |
| Armageddon | Nice challenge in general! angr does not work so it requires some manual work. I dumped the equations with Ghidra and solved it with z3. | 2020-06-17 17:14 |
| de_tcrack1 | interesting one! | 2020-06-16 06:47 |
| XBS | An interesting algorithm! Its complex if only analyzed statically. But debugging helps me out. Thx! | 2020-06-12 11:31 |
| C++ Medium Crackme | Based on stryker2k2's Ghidra crackme's | A not-so-complex algorithm. A nice playground for z3. thx! | 2020-06-10 09:35 |
| KeyMe | nice one, thx! | 2020-06-10 08:51 |
| Simple Crackme | code starting at 0x400418 is both executed as code and later used as the index into the string "BGOTHXIY". Nice one, thx! | 2020-06-10 08:45 |
| Crack Me Reborn V2.0 | yeah, as x0r19x91 said, this one seems to have some problem which makes it quite easy to solve. | 2020-06-10 08:38 |
| Medium Crackme | Interesting one! A modified ROT13 algorithm. | 2020-06-10 08:28 |
| Get into that base! | RzAwRCBKMEIhCg A moderately complex algorithm accompanied by some mild math obfuscations. Probably a level 2-3. | 2020-06-09 11:45 |
| QR Scanner | This one is really hard and let us solve it! | 2020-05-28 09:56 |
| KidoMe x64 | nice obfuscations! for the hash, I used z3 to find valid keys. | 2020-05-28 09:51 |
| hell86 | I wrote a static disassembler for this. Not too hard but takes some time | 2020-05-11 12:49 |
| hell86 | nice one, thx! | 2020-05-11 12:36 |
| Simple CrackMe | thx! | 2020-05-08 10:20 |
| nasm crack | thx! | 2020-05-08 10:18 |
| easyAF | This is really easy. Thx! | 2020-05-08 10:15 |
| Garou.exe | KeygenMe | The algorithm itself is not complex. But the std::string implementation makes it a little bit complex to find it out. | 2020-04-24 04:40 |
| Find password | I found the password! Its quite straightforward to find it | 2020-04-23 04:02 |
| Wacha Wachin | Wow, releasing the challenge in a PDF seems the best way to prevent patching lol | 2020-04-22 13:03 |
| WTF(Where This Flag) | flag 3 is nicely hidden! I actually defined that function but I did not pay any attention to it! | 2020-04-13 15:36 |
| WTF(Where This Flag) | Thanks for the explanation. I will check it out! | 2020-04-13 15:12 |
| WTF(Where This Flag) | Let me rephrase it a little bit so you do not get confused: 1). I see a string in the binary that satisfies the flag format. I will call it "nice jump" flag. My first question is whether this is the first flag? And if it is, is there an input that can trigger the program to print it to the console? Or It is just supposed to be found by looking at the strings. 2. I already found out the correct solution to the maze. And it seems to me there is no maze logic. It just compares the user input with this fixed solution. However, in the end, it asks "where is the flag", so I suppose this maze solution is not really helpful. Again, I wish to find an input that can print the nice jump flag, but failed. 3. For the third flag, I explored all of the functions in the binary but I am not sure whether any execution | 2020-04-13 12:00 |
| WTF(Where This Flag) | It also seems to me there is no maze game logic in the program? It just compares the user input to a fixed solution path. I used turtle to draw the path out it it seems using exploring the maze. | 2020-04-13 11:39 |
| WTF(Where This Flag) | I am curious whether there is a way to let the program print the "nice jump" flag, or it is designed to be find in the strings and that is all of it? | 2020-04-13 11:22 |
| WTF(Where This Flag) | I actually solved the maze. And in the end it prints a line to ask me where is the flag. So I suppose you mean the solution path of the maze somehow form a solution? Btw, is this about the third flag or the first one? | 2020-04-13 11:20 |
| WTF(Where This Flag) | @author, I saw another flag text in the strings. But I cannot find a way to trigger it in the maze. Btw, I found some trace of the third flag, but I cannot figure it out. Do you mind my getting in touch with you? | 2020-04-12 11:50 |
| fary Crackme v1.0 | [Click to reveal]CR:KXR or p%R9L`! | 2020-04-09 07:13 |
| WTF(Where This Flag) | [Click to reveal]it is a clever way to hide the flag! thx for it! sbh{d0n7_u53_r4nd_f0r_cryp7!} | 2020-04-07 01:18 |
| auth | nice one! Need to exploit the vulnerability to solve it. | 2020-04-07 00:11 |
| Small Keygenme | Interesting one! | 2020-04-06 23:54 |
| login-cipher | nice one! Though the algorithm is not complex. | 2020-04-04 05:15 |
| Simple obfuscation | @sheratom. That is malloc(). There are several hints for it. 1). It is super complicated and it does not like part of the code to check the key. 2). It is called a lot of times in the program. 3). Its return value is used as a buffer. | 2020-03-16 06:44 |
| Yet another crackme/keygenme 2 | The author tampers with the ELF to confuse debuggers/disassemblers. The first step is to study the program and fix it. | 2020-03-16 01:41 |
| S3cr3t V4ult | @x0r19x91: I solved it and uploaded my submission yesterday. I like the design! thx! | 2020-02-23 08:29 |
| You will fail | emmm, this looks interesting to me. An Initial shallow investigation tells me it is impossible to solve; but this is only the beginning of the journey. | 2020-02-18 15:25 |
| S3cr3t V4ult | Hi mr_sandman, for static analysis I use Binary Ninja; for dynamic debugging I use x64dbg. And here is a list of tools, tutorials, etc. https://github.com/dsasmblr/game-hacking. Obviously, it is not only for game hacking. | 2020-02-18 03:35 |
| S3cr3t V4ult | I have investigated this sample and it does not seem to contain a virus. It has a very clever design and I think it is underrated as level 2. This design might be the reason for it being flagged by AV engines. However, I cannot make a promise on this -- I am just saying my reverse engineering told me it is a real crackme rather than a virus. | 2020-02-18 03:28 |
