+Simple code for encrypt/decrypt files with xorcipher.
+
+# ZAŠTO OVO?
+
+Zato sta svugdi online svi nude enceypt/decrypt text sa xor cipher, a malo tko nudi za encrypt files...
+
+Jednostavan `.c` kod lagan i esy for usage. 
+
+## Here's how to compile **xorcrypt.c** file to a Win32 executable using **gcc**:
+
+**Method 1**: Using MinGW-w64 (Recommended)
+
+```bash
+# Compile as 32-bit Windows executable
+gcc -m32 -o xorcrypt.exe xorcrypt.c
+
+# Or with more specific options
+gcc -m32 -O2 -s -o xorcrypt.exe xorcrypt.c
+```
+
+**Method 2**: Using Specific Architecture
+
+```bash
+# If you have multiple gcc targets
+i686-w64-mingw32-gcc -o xorcrypt.exe xorcrypt.c
+
+# Or for standard MinGW
+mingw32-gcc -o xorcrypt.exe xorcrypt.c
+```
+
+**Method 3**: With Additional Compiler Flags
+
+```bash
+# Compile with optimizations and stripped debug info
+gcc -m32 -O2 -s -Wall -o xorcrypt.exe xorcrypt.c
+
+# Or for a smaller executable
+gcc -m32 -Os -s -ffunction-sections -fdata-sections -Wl,--gc-sections -o xorcrypt.exe xorcrypt.c
+```
+
+**Installation Options for GCC:**
+
+**Option A**: Install MinGW-w64
+
+ * Download from: `https://www.mingw-w64.org/`
+  * Or use Chocolatey: `choco install mingw`
+    * Or use MSYS2: `pacman -S mingw-w64-i686-gcc`
+
+    **Option B**: Using Visual Studio Developer Command Prompt
+
+    ```bash
+    # Open "Developer Command Prompt for VS" then:
+    cl /Fe:xorcrypt.exe xorcrypt.c
+    ```
+
+    **Usage after compilation:**
+
+    ```bash
+    # Encrypt/decrypt a file
+    xorcrypt.exe input.txt output.txt mypassword
+
+    # Example
+    xorcrypt.exe document.txt encrypted.bin secretkey
+    ```
+
+    **Important Notes**:
+
+* `-m32` flag: Forces 32-bit compilation (remove for 64-bit)
+* `-O2`: Optimization level 2
+* `-s`: Strip debug symbols (smaller executable)
+* `-Wall`: Enable all warnings
+
+If you get "**architecture not supported**" error:
+
+* Install **32-bit** development **libraries**
+
+* Use **i686-w64-mingw32-gcc** specifically for 32-bit Windows
+
+The compiled executable will be a standalone **Win32** console application that can encrypt/decrypt files using **XOR encryption** with the provided key.
