I noticed first row is 3,4,5 multiplied by 2 and third row are the same numbers multiplied by 3.

The good answer seems to be 6, 11, 22 but I don't see how the author gets there

After completing missions in an order I won't tell for spoiler reasons, you can find this text.

Transcribed, it looks like this (Reddit won't allow pasting this code neither here nor in the comments becuase of max characters in a post)

A thought was that it could be a Base64 encoded image, but I had no luck with that. Hex/Base16 obviously didn't do me any luck either, and to me it really doesn't like anything special beyond that. ROTX code seems unreasonable because of the numbers.

Hopefully some decoder-brain in here could lend a hand, and get an amazing game as a prize!

My friend’s old account has this post on his facebook and I was wondering what this cryptic text means. I don’t know where to ask this so I am here to ask for your help to decode this. Thank you in advance.

I found a note on the ground that says "Crack Me"

I have been going at it for an hour and I am getting frustrated.

It is as follows:

"Q IU GWC BW BPM MUL WN BPM TQUM Crack me!"

Howdy!

If you can solve all the puzzles of the prequel, The Case of the Missing Story you can win a free copy of the detective mystery game A Death in the Red Light.

I have 2 copies to give away! DM me with the solutions.

Aw frick I totally forgot my password 😭😭😭 Now I can't login at 167.99.81.27 on port 10001 using netcat 😓. I guess that game key will waste away then ☹️

Here is the password hash I recovered if anyone wants a try:

But I'll have to warn you... my password is protected with 11 (epic) lowercase characters 😎. So don't get salty if you fail 😂

This is a Nintendo Switch code, which has the format XXXX-XXXX-XXXX-XXXX, where each character is an uppercase letter or number.

The 19-character code hashes to 331260c3efcf85452c605c03e092ef22dff1b9730b949ab5419b3bdf1a39a090 using SHA-256.

I created this puzzle to celebrate the upcoming film. Some knowledge of Pokemon Red/Blue/Yellow is necessary, and the key to the first puzzle will help with the second puzzle. I will add more hints and clarifications if necessary.

I broke the 3DS key into two halves and replaced the numbers with words (1 to ONE, 2 to TWO, etc.).

The first half is a 14-character string that conspicuously replaces the word "destiny" in the plaintext for Part 1 and hashes to c6597cd7405c036c9af3fa1b525c3b52faadfd626198aed6ddd8958674b6cda0.

The second half is a 19-character string that conspicuously replaces the word "grass" in the plaintext for Part 2 and hashes to eb9da085db8eb5d65d76758f7d5c1bd17290a35eae77b14c15bacef41ad7371f.

After turning the words back to numbers, the SHA-256 hash of the final, 16-character 3DS key is 04c8988e38dc838f235127315ceb5d5d1fd20d5a25e838fd6b0854b0c5116581.

We found the following document somewhere lying around on a shipwreck, and we are convinced there's a treasure or a treasure map in there. Can you find it?

https://pastebin.com/i2hvbCx9

(if you saw the previous version of this post, please disregard that, as the encryption was too weak and the key wasn't present)

This steam key comes in the xxxxx-xxxxx-xxxxx, where the x’s are capital letters or numbers.

You can find the key here.

The md5 hash of the key (without hyphens) is 5f04632b29918a2989da6f8b61449e5f.

Good luck!

Temporary edit: there was a problem with the initial zip file. I have removed it for now, and will update the link (along with a message) when it is fixed. My sincerest appologies for those who started cracking...

The zip should now be fixed, my apologies for the inconvenience caused.

This is a steam key, which comes in the form xxxxx-xxxxx-xxxxx, where the x’s are capital letters or numbers.

We used a certain encryption scheme on the entire key (without hyphens), and this gave the output 5LQ0N6BYAUPHFJXPZIK5D4ONTQTWN. The same encryption scheme produced the following on some examples

A -> UV

B -> 34

C -> M

ABC -> 4J55

KEY -> 10WCH4F

CLOSE -> 1F6JLP27

1KV -> B

2 -> B

(Hint: think in binary)

The hash of the entire key (without hyphens again) is 8E6E66804A43093452D8BB7E9EDA9F18.

Good luck!

Edit: added a hint

Edit: The encoded key was wrong, as pointed out by u/Randomiser. It's fixed now.

This is a steam key, which comes in the format xxxxx-xxxxx-xxxxx, where the x’s are capital letters or numbers.

In this text file , find the total sum of all the calculations and call this z. Then the key converted from base 36 to base 10 is equal to z - 76244809007158401894839.

Good luck!

Hint: XY-YX

Keep up the good work people!

The reward is a steam key in the form AAAAA-AAAAA-AAAAA where each A can be [A-Z0-9].

There exists a single number in this pastebin file with the following properties:

• It is a 15 digit Base 36 number (where A-Z maps to 10-35)
• All digits are consecutive (i.e. all 15 digits are part of a single 15 character substring of the text)
• If reduced by 4 the number becomes a prime number

If you found the number insert the 2 hyphens and get your game.

Have fun :)

PS: This is my first post on this subreddit, so don't hate please :) Also i don't know if the difficulty of my code is adequate. Please tell me, so i can make it easier/harder next time.

This steam key comes in the form AAAAA-BBBBB-CCCCC where the A, B and C are capital letters or numbers.

The last 3 characters of AAAAA are the bay and the country in the following picture. The others can also be found in the picture.

We converted BBBBB from base 36 to base 10, this gave a certain number x. Then x^(3)+x+1 mod 2147483647 = 2056384123.

You can find CCCCC here.

Good luck!

Edit: AAAAA was slightly unclear so I added some additional information.

The reward is a steam key in the form AAAAA-BBBBB-CCCCC. As usual, capital letters and digits.

AAAAA: I seem to like encodings

BBBBB: User input validation can be tricky

CCCCC: Don't trust your eyes

I tried to make it slightly less hard than my (still unsolved) Teslagrad challenge. If you want to know whether you're on the right path or you want to verify partial solutions, feel free to drop a message.

The code comes in the form AAAAA-BBBBB-CCCCC. AAAAA,BBBBB and CCCCC were converted (from base 36) to binary strings with length 25,26 and 24 respectively. These strings were concatenated to form a 75 bit string.

This message was then transmitted over a network using 4 packages. One packet however was lost during transmission. Luckily we used some kind of forward error correction.

The received packets were: 1010000101011101111100011 1101011000110111110010010 1010100011000101000001010

in that order.

Good Luck!

If you thought this challenge was easy you might want to leave the key for one of our newer members.

This steam key comes in the form xxxxx-xxxxx-xxxxx, where the x’s are capital letters or numbers.

Let m be the key without hyphens, converted from base 36 to base 10. Bob wants to privately send this key to both Alice and Anna. They use RSA for this, see https://en.wikipedia.org/wiki/RSA_(cryptosystem) for more information. Alice and Anna use the same value of n for their public key, this is 7039155432311088712096080213790997488546825780010282082951498556747517816202753235797481633771239715470599856957831129125144951809292819568181428802762486602513148006608098677415001236525322295065287567336268276244846262191740426316786551176858729778093135910202223188365281948380210782753600670882002281548326979303730237130509478556324653192849262230723780743181330289776595404070002790847544051962644369792166597367770221721801197683427071.

For the other part of their public key (this is usually called e), they use the following

Good luck!

This steam key comes in the form xxxxx-xxxxx-xxxxx where the x’s are capital letters or numbers.

The key can be found in https://pastebin.com/7Qpdrj9C. In this text, find every substring of the form a[number]b*, where [number] is a number (the empty string is not considered a number) and where * is any character. The *’s together form the key.

Good luck!

This blizzard key comes in the form xxxx-xxxx-xxxxx-xxxx-xxxx (so 21 characters) where each x is either a capital letter or a number.

Our code for this challenge was encrypted using the following method:

First we put our code somewhere in an english text and encrypted this text using the ROT0 Vigenere cipher.

We then used a columnar transposition cipher on the encrypted text to finish it off.

Another three hints are also provided:

• The column transposition key length is at most 10.
• The Vigenère key length is between 1 - 21.
• The code only contains characters.

Edit: I made a mistake when copying the key. I don't have time to fix this right now but I'll do it in a couple of hours. Also, the key was only 21 characters.

Edit: The challenge is fixed.

This key comes in the form XXXXX-XXXXX-XXXXX where every X is either a number or a capital letter.

If we put the entire string together ( XXXXXXXXXXXXXXX) we can refer to each character by their index. The first character has index 1, the second character has index 2, ... , the last character has index 15.

The X’s with an even index have been encrypted with the following SHA512 hash :

80fbd3da3b536d00352236363d51ae7b02e40c042f3a96b3e90484c50cbcda39ea944c3e48eeeee387f5e4f4e95593424984ea4712ee6561505195f579e02823

The X’s with an index that is divisible by 3 are encrypted with the following MD5 hash:

8f2854aebcb0e0f27dfb4ac86241f462
