+# AST1060 Digest Server Integration
+
+This document describes the integration of the digest server into the AST1060 application.
+
+## Changes Made
+
+### 1. Application Configuration (`app/ast1060-starter/app.toml`)
+
+Added the digest server task:
+
+```toml
+[tasks.digest_server]
+name = "digest-server"
+priority = 2
+max-sizes = {flash = 16384, ram = 4096}
+start = true
+stacksize = 2048
+```
+
+- **Priority 2**: Same as UART driver, suitable for service tasks
+- **Flash**: 16KB allocated for the digest server code
+- **RAM**: 4KB allocated for session management and buffers
+- **Auto-start**: Server starts automatically with the system
+
+### 2. Task Dependencies
+
+Updated the helloworld task to include digest server access:
+
+```toml
+[tasks.helloworld]
+# ... existing config ...
+task-slots = ["uart_driver", "digest_server"]
+```
+
+This gives the helloworld task IPC access to the digest server.
+
+### 3. Kernel Resources
+
+Updated kernel requirements to accommodate the new task:
+
+```toml
+[kernel]
+name = "ast1060-starter"
+requires = {flash = 25000, ram = 4096}  # Increased from 20000/3072
+```
+
+## Demonstration Features
+
+The updated helloworld task now demonstrates:
+
+### 1. One-Shot Digest Operations
+- SHA-256 hashing of static data
+- SHA-384 hashing (showing first 8 words)
+- SHA-512 hashing (showing first 8 words)
+
+### 2. Session-Based Digest Operations
+- Multi-chunk hashing using sessions
+- Proper session lifecycle management
+- Demonstrates incremental data processing
+
+### 3. Interactive Features
+- Hashes any data received via UART
+- Displays hash results in hexadecimal format
+- Comprehensive error handling and reporting
+
+## Expected Output
+
+When the system boots, you should see:
+
+```
+Hello, world from AST1060!
+Testing digest server...
+Testing one-shot SHA-256...
+SHA-256 result: 6A09E667BB67AE856A09E66873A5A6726A09E667...

+Session SHA-256 result: 6A09E667BB67AE856A09E66873A5A6726A09E667...

+Testing SHA-512...
+SHA-512 result: 6A09E667BB67AE856A09E66773A5A6726A09E667...
+Digest server testing complete!
+```
+
+When you send data via UART, you'll also see the hash of that data.

+## Resource Usage
+
+- **Total Flash**: ~25KB (kernel + all tasks)
+- **Total RAM**: ~4KB (kernel + all tasks)
+- **Digest Server**: 16KB flash, 4KB RAM
+- **Session Limit**: 8 concurrent digest sessions
+- **Buffer Limit**: 1024 bytes per operation
+
+## Building and Running
+
+From the workspace root:
+
+```bash
+# Build the application
+cargo xtask build --app ast1060-starter
+
+# Flash to hardware (if available)
+cargo xtask flash --app ast1060-starter
+
+# Run in QEMU (if supported)
+cargo xtask run --app ast1060-starter
+```
+
+## Testing the Digest Server
+
+1. **Boot Test**: System should boot and show digest test results
+2. **UART Test**: Send text via UART and observe hash output
+3. **Algorithm Test**: Verify different hash algorithms work
+4. **Session Test**: Verify session-based operations work
+5. **Error Test**: Test error conditions (though limited in current mock)
+
+## Future Enhancements
+
+1. **Hardware Backend**: Replace mock with AST1060 crypto hardware
+2. **Performance Testing**: Measure actual hash performance
+3. **Stress Testing**: Test session limits and error conditions
+4. **Security Features**: Add HMAC and authenticated operations
+5. **Power Management**: Add sleep/wake support for the digest server

+
+The AST1060 application is now ready to be built with the integrated digest server:
+
+```bash
+# From workspace root
+cd /home/ferrite/rusty1968/initiative/hubris
+
+# Build the complete application
+cargo xtask build --app ast1060-starter
+
+# Flash to hardware (when available)
+cargo xtask flash --app ast1060-starter
+```
+
+The system will demonstrate both the digest server functionality and provide an interactive way to test hashing operations via UART input.
