# XORCIPHER

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.
