A quick google search I find that the RLEextension is related to Run Length Encoded Bitmaps.

Further searching I find that there is a tool called “Golly” for viewing RLE files.

I let the online webapp load and then open my golly.rle file in it:

That gives me the flag in a scrolling marquis-type display:

UDCTF{th3y_c4ll_thems3lves_the_fl4g_smash3rs}

This was a pretty unique challenge.

As recommended by the challenge text, I got the latest Minecraft Java Launcher and launched a world:

I followed the YouTube video and gave myself a command block, placed it with a button on it, and posted the mc86 initcode:

I clicked the button and received an enchanted book:

I followed the instructions and clicked each of the six links to generate my mc86 computer in my world:

Next, following the YouTube video, I pasted the challenge source code into the command block I created earlier and click the button:

This gave me a 41 page book and quill:

I placed a button in the mc86 computer (as directed in the YouTube video) and and clicked it to run the challenge program:

This created a strange pattern of fence panels with pigs being in holes in some of the sections:

Here is a better view of the whole structure:

Based on the challenge name, I googled for ciphers containing symbols (looking for symbols similar to the fance panels). This led me to the pigpen cipher:

Being lazy, I go to my favorite cipher decoder website… dcode.fr:

I punch in the symbols found in my Minecraft world and click to decrypt it:

This gave me the flag:

For this challenge, we are given the following information and image:

Here is mc.png:

I stared at this once clueless until my son walked in and looked at the screen and just casually said “Get Blocked.”

I asked what he meant and he said “the names of the blocks… those are the first letters of each.

This was the flag:

UDCTF{GETBLOCKED}

For this challenge, we are given a hint and a text file:

A quick trip over to RapidTables and we get this:

Apparently the princess is in another castle. I see that there is what appears to be a base64 encoded string. A quick trip over to Base64Decode and we get this:

Yet another castle. This time I have another string that appears to be a cipher along with a clue. This leads me to think it could be a Caesar Cipher. A quick trip to dcode.fr and I get this:

congratulations! you have finished the beginner cryptography challenge. here is a flag for all your hard efforts: utflag{now_youre_playing_with_crypto}. you will find that a lot of cryptography is building off this sort of basic knowledge, and it really is not so bad after all. hope you enjoyed the challenge!
