# Rust CTF Party


## Description


Rust CTF Party is a tool that provides various cryptographic and network utilities for CTF (Capture The Flag) competitions. It is written in Rust and offers a command-line interface for easy usage.


### How to Use the Tool


To use the tool, you need to provide a command and subcommand. Here are some examples:

1. **Base64 encoding**:
   ```
   rust_ctf_party.exe base64 to-b64 "hello"
   ```

2. **Calculate MD5 hash**:
   ```
   rust_ctf_party.exe digest md5 "hello"
   ```

3. **Rotate text by 13 positions (ROT13)**:
   ```
   rust_ctf_party.exe rot rot13 "hello"
   ```

4. **Check if a string is a valid flag**:
   ```
   rust_ctf_party.exe flag check "flag{example}"
   ```

5. **Convert text to hexadecimal**:
   ```
   rust_ctf_party.exe hex to-hex "hello"
   ```

6. **Check if an IP address is valid**:
   ```
   rust_ctf_party.exe network ipv4 "192.168.1.1"
   ```

### Using Piped Input


You can also pipe input to the tool:

```
echo "hello" | rust_ctf_party.exe base64 to-b64
```

### Getting Help


To get help for a specific command, use:

```
rust_ctf_party.exe base64 --help
```

This will show you all the available subcommands for the base64 command.

### Summary


The error you're seeing is not actually an error - it's the tool telling you that you need to provide a specific command to perform an operation. The tool is working correctly, but you need to specify which operation you want to perform.
