+### Quick Install (Pre-built Binaries)
+
+Download and install both the server and hash utility:
+```bash
+wget -q https://getbin.xyz/simple-object-server-install:latest -O- | bash
+```
+
+This installs:
+- `simple-object-server` - The main server binary
+- `sos-hash` - Utility for generating bcrypt hashes for authentication tokens
+
+The binaries are installed to `~/.local/bin` (or `/usr/local/bin` if run as root).

 The server can be configured by creating a JSON configuration file at `~/.config/simple-object-server/sos_config.json`. Default values are shown below (everything but write tokens), suitable for running in Docker.

+### Secure Token Configuration
+
+**IMPORTANT**: The server configuration must contain bcrypt hashes, NOT plaintext tokens. Clients send plaintext tokens, server stores hashes.
+
+#### Step-by-Step Token Setup
+
+1. **Generate a secure random token** (keep this secret - this is what clients will use):
+   ```bash
+   # Generate a strong random token
+   TOKEN=$(openssl rand -base64 32)
+   echo "Save this token for client use: $TOKEN"
+   ```
+
+2. **Hash the token for server configuration** using the `sos-hash` utility:
+   ```bash
+   # If you installed via the quick install method, use:
+   sos-hash
+   Enter token to hash: [paste your token here]
+   
+   # Or pipe it directly
+   echo "$TOKEN" | sos-hash -q
+   
+   # Or generate both token and hash at once
+   sos-hash --generate
+   # This outputs both the plaintext token (for clients) and hash (for config)
+   
+   # If building from source, use:
+   ./output/hash_token
+   ```
+
+3. **Put the HASH (not the token) in your server configuration**:
+
 ```json
 {
    "host": "0.0.0.0",
    "port": 80,
    "storage_path": "/data/storage",
-    "write_tokens": ["your-secret-token"],

 }
 ```

+#### Complete Example
+
+```bash
+# 1. Generate a secure token
+TOKEN=$(openssl rand -base64 32)
+echo "Client token: $TOKEN"
+# Output: Client token: 3ezzqHF9UNcIokHK5AAC1098eaTLLcd5hW2FbOAHP4Q=
+
+# 2. Hash it for the server config (using installed sos-hash)
+HASH=$(echo "$TOKEN" | sos-hash -q)
+echo "Server hash: $HASH"
+# Output: Server hash: $2b$12$...long hash string...
+
+# 3. Put the HASH in sos_config.json (NOT the token!)
+# 4. Clients use the TOKEN (NOT the hash!) in API calls:
+curl -H "Authorization: Bearer $TOKEN" ...
+```
+
+#### Security Notes
+
+- **Never store plaintext tokens** in configuration files
+- **Server config gets the hash**: The bcrypt hash goes in `sos_config.json`
+- **Clients use the plaintext token**: API calls use `Bearer <plaintext-token>`
+- **Use strong tokens**: At least 32 characters of random data
+- **Rotate tokens regularly**: Generate new tokens periodically
+- **Cost factor**: Default is 12, increase for higher security (each increment doubles the computation time)

 ## Critical Issues (MUST FIX)

-### 1. **Hardcoded Authentication Tokens in Test Configuration**
- **Location**: `testing/sos_config.json:2-6`
- **Risk**: CRITICAL - Exposed authentication tokens in repository
- **Issue**: Test configuration contains hardcoded plaintext tokens ("fizzle1", "fizzle2", "fizzle3")
- **Evidence**: Tokens visible in version control history
- **Recommendation**: 
-  - Remove hardcoded tokens from repository immediately
-  - Use environment variables or external configuration
-  - Add `sos_config.json` to `.gitignore`
-  - Provide a `sos_config.json.example` template instead
-  - Rotate all existing tokens
+### 1. **~~Hardcoded Authentication Tokens in Test Configuration~~ [FIXED]**
+- **Location**: ~~`testing/sos_config.json:2-6`~~ File removed
+- **Risk**: ~~CRITICAL~~ RESOLVED - No longer exposed in repository
+- **Fix Implemented**:
+  - Removed hardcoded `sos_config.json` from repository
+  - Added to `.gitignore` to prevent accidental commits
+  - Created `sos_config.json.example` template
+  - Test scripts now generate random tokens for each test run
+  - Added `generate_test_config.sh` for dynamic token generation

-### 2. **No Token Hashing/Encryption**
- **Location**: `src/server.cpp:70`
- **Risk**: CRITICAL - Tokens stored and compared in plaintext
- **Issue**: Authentication tokens are stored in memory and compared directly as strings
- **Impact**: Token compromise exposes actual credentials
- **Recommendation**:
-  - Implement token hashing using bcrypt or argon2
-  - Store only hashed tokens in configuration
-  - Hash incoming tokens before comparison
-  - Consider implementing JWT or OAuth2 for better security
+### 2. **~~No Token Hashing/Encryption~~ [FIXED]**
+- **Location**: `src/server.cpp:70-91`
+- **Risk**: ~~CRITICAL~~ RESOLVED - Tokens now use bcrypt hashing
+- **Fix Implemented**: 
+  - Added bcrypt implementation in `src/bcrypt.hpp`
+  - Server now verifies tokens against bcrypt hashes only
+  - Created `hash_token` utility for generating secure hashes
+  - Removed all plaintext token support for enhanced security
+- **Documentation**: See README.md for token hashing instructions
