Kelsi 4b48fcdab2 Enhanced Warden implementation with comprehensive documentation
Added MD5 hashing and extensive testing documentation for future attempts
at supporting strict Warden servers like Warmane.

Enhancements:
- Added MD5 hash support to Crypto class (OpenSSL-based)
- Tested 6 different module ACK response formats against Warmane
- Analyzed module packet structure (37 bytes: opcode + seed + trailing)
- Enhanced debug logging for plaintext and encrypted Warden data

Documentation:
- WARDEN_IMPLEMENTATION.md: Complete implementation guide with all attempts
- WARDEN_QUICK_REFERENCE.md: Quick troubleshooting and testing guide

Test Results (Warmane):
- Empty ACK (0 bytes): Server silent
- XOR/MD5 checksum (18 bytes): Server silent
- Single byte (1 byte): Server disconnects (rejected)
- Echo trailing (20 bytes): Server silent
- Result + SHA1 (21 bytes): Server silent

Conclusion:
- Current implementation works with permissive/disabled Warden servers
- Warmane requires module execution or undocumented response format
- Full documentation provided for future reverse engineering attempts

Next steps documented:
1. Capture packets from real WoW client (protocol analysis)
2. Implement module execution engine (months of work)
3. Test with local AzerothCore server

# Warden Quick Reference
## TL;DR
**What works**: Servers with Warden disabled or permissive settings
**What doesn't work**: Warmane (requires module execution)
**What we have**: Complete crypto system, no module execution
---
## Testing a New Server
1. **Check if Warden is required**:
```
Connect → Look for SMSG_WARDEN_DATA (0x2E6)
If no Warden packet → Server doesn't use Warden ✅
If Warden packet → Continue testing
```
2. **Watch for server response**:
```
After CMSG_WARDEN_DATA sent:
- Gets SMSG_CHAR_ENUM → SUCCESS ✅
- Connection stays open but silent → Rejected ⏸️
- Connection closes → Rejected ❌
```
3. **Check logs**:
```bash
tail -f logs/wowee.log | grep -i warden
```
Look for:
- `packetsAfterGate=0` (bad - server silent)
- `packetsAfterGate>0` (good - server responding)
---
## Quick Fixes
### Server Goes Silent
**Symptom**: Connection stays open, no SMSG_CHAR_ENUM
**Cause**: Server doesn't accept our response format
**Fix**: Try different response format (see below)
### Server Disconnects
**Symptom**: Connection closes after Warden response
**Cause**: Response is definitely wrong
**Fix**: Don't use that format, try others
### Can't Get Past Warden
**Solution 1**: Use a server with Warden disabled
**Solution 2**: Contact server admin for test account
**Solution 3**: Implement module execution (months of work)
---
## Trying New Response Formats
Edit `src/game/game_handler.cpp` around line 1850:
```cpp
std::vector<uint8_t> moduleResponse;
// Try your format here:
moduleResponse.push_back(0xYOUR_BYTE);
// Add more bytes...
// Existing code encrypts and sends
```
Rebuild and test:
```bash
cd build && cmake --build . -j$(nproc)
cd bin && ./wowee
```
---
## Response Formats Already Tried (Warmane)
| Format | Bytes | Result |
|--------|-------|--------|
| Empty | 0 | Silent ⏸️ |
| `[0x00][MD5][0x01]` | 18 | Silent ⏸️ |
| `[0x01]` | 1 | Disconnect ❌ |
| `[20-byte echo]` | 20 | Silent ⏸️ |
| `[0x01][SHA1]` | 21 | Silent ⏸️ |
---
## Module Packet Structure
```
Byte Content
0 Opcode (varies each packet)
1-16 Seed (16 bytes for RC4)
17-36 Trailing data (20 bytes, possibly SHA1)
```
---
## Crypto Overview
```cpp
// Initialize (first packet only)
wardenCrypto_->initialize(moduleData);
// Decrypt incoming
auto plain = wardenCrypto_->decrypt(encrypted);
// Encrypt outgoing
auto encrypted = wardenCrypto_->encrypt(plain);
```
Keys are derived from:
- Hardcoded Warden module key (in `warden_crypto.cpp`)
- 16-byte seed from server
- XOR operation for output key
---
## Check Types Reference
| Opcode | Name | What It Checks | Our Response |
|--------|------|----------------|--------------|
| 0x00 | Module Info | Module status | `[0x00]` |
| 0x01 | Hash Check | File/memory hashes | `[0x01][0x00...]` |
| 0x02 | Lua Check | Suspicious addons | `[0x02][0x00]` |
| 0x04 | Timing | Speedhacks | `[0x04][timestamp]` |
| 0x05 | Memory | Memory scans | `[0x05][num][0x00...]` |
All responses are **faked** - we don't actually check anything.
---
## Common Errors
**Build fails**: Missing OpenSSL
```bash
sudo apt-get install libssl-dev
```
**Crypto init fails**: Bad module packet
```
Check log for "Warden: Initializing crypto"
Ensure packet is at least 17 bytes
```
**Always disconnects**: Server detects fake client
```
No easy fix - need module execution or different server
```
---
## Next Steps for Warmane Support
1. **Capture real WoW client packets** (Wireshark)
2. **Compare with our responses** (find differences)
3. **Implement matching format** (edit game_handler.cpp)
4. **OR**: Implement module execution (months)
