+Reversing is hard. This time moreso than the last, but now by much.
+
+This file is a compiled executable binary (which we refer to as just "binary" for short).
+
+The process of compiling code is extremely complicated, but thankfully you don't need to know much about it to solve this challenge. At a high level, the source code is getting translated from a human-readable text file (not provided) to something much harder to read.... Try `cat`ing the file; it don't work so good. Much of the data in the program is encoded in such a way that makes it easier for the computer to understand - but there are still some elements in there intended to be interacted with by the user. So the question becomes "How do we extract that information?" And eventually "How to we better display that information intended for the computer to understand for a human to understand instead?" But that next question is for the next challenge...
+
+And like we have tools for working with text (such as text editors, `cat`, whatever you're reading this in), there are tools for working with binaries as well. In Linux (it will be helpful to have a Linux VM or Linux system to run these programs in, though technically not required), you can install "bin utils". Most notably, binutils includes `objdump` and `strings`. One of those are what you need to solve this challenge...
+
+Remember, the first rule of reading code is:
+
+DON'T
+
+READ
+
+THE
+
+CODE
+
+(just read the important bits... 👀)

+# Description
+
+A simple rev challenge where the user inpects the binary code to figure out the desired input for the flag.
+
+# Flag
+
+`csawctf{c20ad4d76fe97759aa27a0c99bff6710}``
+
+# Solution
+
+open the binary file in Ghidra.
+
+Look at the exports folder to see the exported functions from the binary. There you will find the main function.
+
+Once you have the main function in the decompiler window, you will see the string of the terminal ouput. This will prove that you are in the main function.
+
+You will see that there is for loop incrementing with the number of char variables inside the user's input. 
+
+The variable is then checked in a conditional to see if it matches the hex value "0xc", which is 12 in decimal. 
+
+Once you submit a 12-character long input, it will execute the correct code block in the if-else statement. This will return the flag, with is the md5 encoding of the string "12".

+
+# Flag
+
+`csawctf{01011100010001110000}`
+
+# Solution
+
+Given the binary, we need to inspect the decompiled ELF file in ghidra.
+
+We can see that there is not user input being accepted, but rather a hardcoded string is parsed through.
+
+It looks like ever second character is passed to a function called "printbinchar".
+
+Looking at printbinchar(), we see that each character is converted into a binary.
+
+The characters that are passed through would be "AY7Cw" and the binary of each value would be:
+
+A = 01000001
+Y = 01011001
+7 = 00110111
+C = 01000011
+w = 01110111
+
+For each character, the "xoring" function is called. The binary for each character is passed through this function.
+
+In the xoring() function, the binary is split down the middle into two 4-bit arrays. Then the xor operation is executed between the two arrays. The result for each character would be:
+
+A = XOR(0100, 0001) = 0101
+Y = XOR(0101, 1001) = 1100
+7 = XOR(0011, 0111) = 0100
+C = XOR(0100, 0011) = 0111
+w = XOR(0111, 0111) = 0000
+
+with each XOR result concatenated in order, this returns the flag:

+# rox 
+
+This challenge primarily involves significant xoring of some data with the goal of getting a password which can open a file. None of the flags can open the file but the final one needs to be password matched to be continued.
+
+Also this was compiled on GCC in FreeBSD so dynamic analysis would probably need a VM or some compatibility layer. You can open this up statically though.
+
+Author: Aneesh Maganti
+
+# Solution
+
+Look in the food_tests.cpp file to find the password. This originally was supposed to open a 7z file which is why the password doesn't have the normal flag{} formatting. 
+
+# Note
+
+the password is not enclosed in a flag{}, see challenge.json for more information on flag format
+
+# TestPlay Solution
+
+Don't have freebsd so the solution is static analysis
+
+func verify:
+1. before the first loop, there is a vector of size 45 with vector arr 
+
+2. First for loop iterates through key and xor by a1
+
+3. second for loop iterates through arr and c = key[i], j = (i * 10 + 12) % size(data), of which data is a giant blob of 4 byte nums at add 0x403680, then assign k = data[j % size(data)]. after which k = k + a1[i % sizeof(a1)] After which k = c ^ data[k % sizeof(data)], then key[i] = k
+
+4. third for loop iterates from 5 to key size, 
+5. inner loop, iterate from 0 to 299, k = key[i], l = j * 32 ^ key[i], l = l ^ (key[i-5] == 110), key[i] = l
+
+then the out is compared to "flag{ph3w...u finaLly g0t it! jump into cell}". 
+
+Write exfil.py which exfils the data listed above, the data is 3497 int wide, or 13988 bytes wide
+
+then essentially do the reverse
+
+replcation:
+
+first loop:
+
+```
+for (int i = 0; i < a1; i++)
+{
+    key[i] = a1[i] ^ key[i]
+}
+```
+
+second loop:
+
+```
+for(int i = 0; i < sizeof(key); i++)
+{
+    int c = key[i];
+    int j = (i * 10 + 12) % sizeof(data);
+    int k = data[j % sizeof(data)]
+    k = k + a1[i % sizeof(a1)]
+    k = c ^ data[k % sizeof(data)]
+    key[i] = k
+}
+```
+
+third loop:
+
+```
+for(int i = 5; i < sizeof(key); i++)
+{
+    for(int j = 0; j < 300; j++)
+    {
+        int k = key[i];
+        int l = j * 32 ^ key[i];
+        //notice this is optimized out 
+        //as xor by same number 300 times result in the same num
+        l = l ^ (key[i-5] == 110);
+        key[i] = l;
+    }
+}
+```
+
+Note: This challenge would be bruteforceable if not for the third loop

+Here is the solution to this CTF:
+
+- Before the first loop, there is a vector of size 45 with vector arr 
+- First for loop iterates through key and xor by a1
+- Second for loop iterates through arr and c = key[i], j = (i * 10 + 12) % size(data), of which data is a giant blob of 4 byte nums at add 0x403680, then assign k = data[j % size(data)]. after which k = k + a1[i % sizeof(a1)] After which k = c ^ data[k % sizeof(data)], then key[i] = k
+- Third for loop iterates from 5 to key size, 
+- Inner loop, iterate from 0 to 299, k = key[i], l = j * 32 ^ key[i], l = l ^ (key[i-5] == 110), key[i] = l
+- Then the out is compared to "flag{ph3w...u finaLly g0t it! jump into cell}"
+- Write exfil.py which exfils the data listed above, the data is 3497 int wide, or 13988 bytes wide
+- Then essentially do the reverse

+Reversing is hard. But, I hate to break it to you, you haven't really been reversing up to now.
+
+This program still has the flag embedded in it, but now it's obfuscated.
+
+You'll need to figure out:
+ 1. What the program is doing
+ 2. How it obfuscates the flag
+ 3. How you can recover the flag
+
+You can use `objdump` to read the raw disassembly of the file, but that's extremely complicated.
+Instead, let's use a tool that'll simply the output for us. I recommend a free decompiler, like:
+ - Dogbolt (lets you see the output of many tools at once): https://dogbolt.org/
+ - Binary Ninja Demo or Cloud (cloud lets you collab with your team members!): https://binary.ninja/demo/
+ - Ghidra (though setting up Java can be a pain): https://ghidra-sre.org/

+This is the first "real" reversing task. You need to use a disassembler or decompiler to view the code. See readme.txt for some suggestions.
+
+When you open the file, you should be able to tell that your input is getting mutated and then compared to a nonsense array.
+
+The mutation happening to your input is a single-byte repeating XOR with a key of `0xAA`. If you apply that same transformation on the array, you get the flag (because XOR is symetric).

+          What is a Metal Gear?
+        </Typography>
+        <Typography variant="body2" paragraph>
+          A Metal Gear is a colossal, bipedal, nuclear-armed mech with the potential to wreak havoc on a global scale.
+          Often used as a tool of warfare, its formidable power can disrupt the balance of world affairs. Identifying
+          one requires vigilance and knowledge.

+          How to Identify a Metal Gear?
+        </Typography>
+        <Typography variant="body2" paragraph>
+          Metal Gears are characterized by their massive size, armored structure, and advanced weaponry. They are designed
+          for both land and water operations. Vigilance is key; be on the lookout for unusual military developments,
+          secret research facilities, and unexplained disappearances that could indicate the presence of a Metal Gear.
+        </Typography>
