+```
+
+## Prerequisites
+
+### 1. Install Skopeo (Host Machine)
+
+```bash
+# Ubuntu/Debian
+sudo apt-get install skopeo
+
+# macOS
+brew install skopeo
+
+# Or build from source
+git clone https://github.com/containers/skopeo
+cd skopeo
+make bin/skopeo
+sudo make install
+```
+
+### 2. Start KBS Server (Host Machine)
+
+```bash
+# Clone and build KBS
+git clone https://github.com/confidential-containers/trustee
+cd trustee/kbs
+# Patch Cargo.toml to disable SGX requirement (for testing only)
+sed -i 's/"all-verifier",//g' Cargo.toml
+
+make
+make cli
+
+# Generate admin keys
+openssl genpkey -algorithm ed25519 -out kbs-admin.key
+openssl pkey -in kbs-admin.key -pubout -out kbs-admin.pub
+
+# Create KBS configuration file
+cat > kbs-config.toml << 'EOF'
+[http_server]
+sockets = ["0.0.0.0:8080"]
+insecure_http = true
+
+[admin]
+type = "Simple"
+[[admin.personas]]
+id = "admin"
+public_key_path = "kbs-admin.pub"
+
+[attestation_service]
+type = "coco_as_builtin"
+work_dir = "kbs-data/as"
+
+[attestation_service.rvps_config]
+type = "BuiltIn"
+
+[attestation_service.rvps_config.storage]
+type = "LocalFs"
+file_path = "kbs-data/rvps-values"
+
+[[plugins]]
+name = "resource"
+type = "LocalFs"
+dir_path = "kbs-data/repository"
+EOF
+
+# Create configuration directories
+mkdir -p kbs-data/as kbs-data/rvps kbs-data/repository
+
+# Start KBS
+sudo ../target/release/kbs --config-file kbs-config.toml
+```
+
+KBS will listen on `http://localhost:8080`
+
+### 3. Setup Local OCI Registry (Optional)
+
+For testing, you can use a local registry:
+
+```bash
+docker run -d -p 5000:5000 --name registry registry:2
+```
+
+## Creating Encrypted Resources
+
+### Encrypt an Algorithm (Python Script)
+
+```bash
+# 1. Create a simple algorithm
+cat > lin_reg.py << 'EOF'
+import pandas as pd
+from sklearn.linear_model import LinearRegression
+import sys
+import os
+
+# Load dataset
+data = pd.read_csv(sys.argv[1])
+X = data[['feature1', 'feature2']]
+y = data['target']
+
+# Train model
+model = LinearRegression()
+model.fit(X, y)
+
+# Save results
+os.makedirs("results", exist_ok=True)
+with open("results/output.txt", "w") as f:
+    f.write(f"Coefficients: {model.coef_}\n")
+    f.write(f"Intercept: {model.intercept_}\n")
+
+print(f"Coefficients: {model.coef_}")
+print(f"Intercept: {model.intercept_}")

+
+## Running a Computation
+
+### 1. Start Manager (Host)
+
+```bash
+cd /path/to/cocos-ai
+./build/cocos-manager
+```
+
+### 2. Start CVMS Test Server (Host)
+
+Get your host IP:
+```bash
+HOST_IP=$(ip -4 addr show | grep -oP '(?<=inet\s)\d+(\.\d+){3}' | grep -v 127.0.0.1 | head -n1)
+```
+
+Start CVMS server:
+```bash
+# Calculate SHA3-256 of decrypted files using cocos-cli or cvms-test
+# NOTE: We use the hash of the original plaintext files, as the Agent validates the decrypted content.
+# For single files, use the file hash. For directories, use the hash of the directory (which the tools zip deterministically).
+
+ALGO_HASH=$(./build/cocos-cli checksum lin_reg.py 2>&1 | awk '{print $NF}')
+

+### 3. Create VM via CLI (Host)
+
+```bash
+export MANAGER_GRPC_URL=localhost:7002
+./build/cocos-cli create-vm \
+  --server-url $HOST_IP:7001 \
+  --log-level debug
+```
+
+The agent will:
+1. Receive computation manifest from CVMS
+2. Use Skopeo to download encrypted OCI images
+3. Skopeo invokes CoCo Keyprovider via ocicrypt
+4. CoCo Keyprovider requests decryption key from KBS
+5. Attestation Agent generates TEE evidence for KBS
+6. KBS validates evidence and returns decryption key
+7. Image layers are decrypted and extracted
+8. Computation executes with decrypted algorithm and dataset
+
+## Verifying the Setup
+
+### Check CoCo Keyprovider Status (Inside CVM)
+
+```bash
+# SSH into CVM or use console
+systemctl status coco-keyprovider
+journalctl -u coco-keyprovider -f
+```
+
+### Check Attestation Agent Status
+
+```bash
+systemctl status attestation-agent
+journalctl -u attestation-agent -f
+```
+
+### Test Skopeo Decryption Manually
+
+```bash
+# Inside CVM
+export OCICRYPT_KEYPROVIDER_CONFIG=/etc/ocicrypt_keyprovider.conf
+
+skopeo copy \
+  --src-tls-verify=false \
+  --dest-tls-verify=false \
+  --decryption-key provider:attestation-agent:cc_kbc::null \
+  docker://localhost:5000/encrypted-lin-reg:v1.0 \
+  oci:/tmp/decrypted-algo
+
+# Verify decryption
+skopeo inspect oci:/tmp/decrypted-algo | jq -r '.LayersData[].MIMEType'
+# Should show: application/vnd.oci.image.layer.v1.tar+gzip
+```
+
+## Computation Manifest Format
+
+The CVMS server sends this manifest to the agent:
+
+```json
+{
+  "computation_id": "1",
+  "algorithm": {
+    "type": "oci-image",
+    "uri": "docker://localhost:5000/encrypted-lin-reg:v1.0",
+    "encrypted": true,
+    "kbs_resource_path": "default/key/algo-key"
+  },
+  "datasets": [
+    {
+      "type": "oci-image",
+      "uri": "docker://localhost:5000/encrypted-iris:v1.0",
+      "encrypted": true,
+      "kbs_resource_path": "default/key/dataset-key"
+    }
+  ],
+  "kbs_url": "http://192.168.100.15:8080"
+}
+```
+
+## Troubleshooting
+
+### CoCo Keyprovider Not Starting
+
+```bash
+# Check logs
+journalctl -u coco-keyprovider -n 50
+
+# Verify socket is listening
+ss -tlnp | grep 50011
+
+# Check environment
+cat /etc/default/coco-keyprovider
+```
+
+### Skopeo Decryption Fails
+
+```bash
+# Verify ocicrypt config
+cat /etc/ocicrypt_keyprovider.conf
+
+# Test keyprovider connection
+grpcurl -plaintext 127.0.0.1:50011 list
+
+# Check KBS connectivity from CVM
+curl http://HOST_IP:8080/kbs/v0/auth
+```
+
+### KBS Returns 401
+
+```bash
+# Check KBS logs on host
+# Verify attestation evidence format
+# Ensure KBS is configured for sample attestation
+```
+
+## Differences from Previous Approach
+
+| Aspect | Old (Custom) | New (CoCo Standard) |
+|--------|-------------|---------------------|
+| **Download** | Custom S3/HTTP clients | Skopeo (OCI standard) |
+| **Decryption** | Custom KBS client | CoCo Keyprovider |
+| **Attestation** | Direct KBS RCAR | AA → CoCo KP → KBS |
+| **Format** | Raw encrypted files | OCI encrypted images |
+| **Complexity** | ~2000 lines custom code | Standard CoCo components |
+
+## Benefits
+
+1. **Standards Compliance**: Uses OCI and CoCo standards
+2. **Better Tooling**: Leverage Skopeo, Docker, Podman ecosystem
+3. **Simplified Code**: Remove custom registry/decryption logic
+4. **Proven Solution**: Battle-tested CoCo components
+5. **Docker Native**: Works with existing Docker workflows
+
+## Next Steps
+
+- Encrypt your algorithms and datasets as OCI images
+- Push to your preferred OCI registry (Docker Hub, GHCR, etc.)
+- Update computation manifests to use `oci-image` type
+- Test end-to-end flow with encrypted workloads

+# CoRIM Generation CLI Commands
+
+This document describes the CLI commands for generating CoRIM (Concise Reference Integrity Manifest) attestation policies.
+
+## Overview
+
+The `cocos-cli policy create-corim` command provides subcommands for generating CoRIM policies for different platforms:
+- **azure**: Generate from Azure Attestation Token
+- **gcp**: Generate from GCP endorsements
+- **snp**: Generate for AMD SEV-SNP (direct host generation)
+- **tdx**: Generate for Intel TDX (direct host generation)
+
+## Commands
+
+### Azure SEV-SNP
+
+Generate CoRIM from an Azure Attestation Token (JWT).
+
+```bash
+cocos-cli policy create-corim azure --token <path-to-token> [--product <product>]
+```
+
+**Flags:**
+- `--token` (required): Path to file containing Azure Attestation Token (JWT)
+- `--product` (optional): Processor product name (default: "Milan")
+
+**Example:**
+```bash
+cocos-cli policy create-corim azure \
+  --token /path/to/token.jwt \
+  --product Milan \
+  > azure-policy.corim
+```
+
+### GCP SEV-SNP
+
+Generate CoRIM from GCP SEV-SNP measurement and endorsements.
+
+```bash
+cocos-cli policy create-corim gcp --measurement <hex> [--vcpu <num>]
+```
+
+**Flags:**
+- `--measurement` (required): 384-bit measurement hex string
+- `--vcpu` (optional): vCPU number (default: 0)
+
+**Example:**
+```bash
+cocos-cli policy create-corim gcp \
+  --measurement abc123... \
+  --vcpu 0 \
+  > gcp-policy.corim
+```
+
+### SEV-SNP (Direct Host)
+
+Generate CoRIM for AMD SEV-SNP platform directly on the host.
+
+```bash
+cocos-cli policy create-corim snp [flags]
+```
+
+**Flags:**
+- `--measurement` (optional): Measurement/Launch Digest (hex string, defaults to zero if not provided)
+- `--policy` (optional): SNP policy flags (default: 0)
+- `--svn` (optional): Security Version Number/TCB (default: 0)
+- `--product` (optional): Processor product name (default: "Milan")
+- `--host-data` (optional): Host data (hex string)
+- `--launch-tcb` (optional): Minimum launch TCB (default: 0)
+- `--output` (optional): Output file path (default: stdout)
+
+**Examples:**
+
+Generate with defaults (zeroed measurement):
+```bash
+cocos-cli policy create-corim snp \
+  --product Milan \
+  --output snp-policy.corim
+```
+
+Generate with custom measurement:
+```bash
+cocos-cli policy create-corim snp \
+  --measurement abc123def456... \
+  --product Genoa \
+  --svn 1 \
+  --policy 0x30000 \
+  --output snp-policy.corim
+```
+
+Generate with host data and launch TCB:
+```bash
+cocos-cli policy create-corim snp \
+  --measurement abc123... \
+  --host-data deadbeef \
+  --launch-tcb 1 \
+  --output snp-policy.corim
+```
+
+### TDX (Direct Host)
+
+Generate CoRIM for Intel TDX platform directly on the host.
+
+```bash
+cocos-cli policy create-corim tdx [flags]
+```
+
+**Flags:**
+- `--measurement` (optional): MRTD measurement (hex string, uses default if not provided)
+- `--svn` (optional): Security Version Number (default: 0)
+- `--rtmrs` (optional): Comma-separated RTMRs (hex)
+- `--mr-seam` (optional): MRSEAM (hex)
+- `--output` (optional): Output file path (default: stdout)
+
+**Examples:**
+
+Generate with defaults (matches legacy script behavior):
+```bash
+cocos-cli policy create-corim tdx \
+  --output tdx-policy.corim
+```
+
+Generate with custom values:
+```bash
+cocos-cli policy create-corim tdx \
+  --measurement abc123def456... \
+  --rtmrs rtmr0,rtmr1,rtmr2,rtmr3 \
+  --mr-seam 789abc... \
+  --svn 2 \
+  --output tdx-policy.corim
+```
+
+## Signing CoRIMs
+
+CoRIMs can be signed using a private key (COSE_Sign1). The generated output will be a COSE-wrapped CoRIM in CBOR format.
+
+### Prerequisite: Generate Signing Key
+
+You will need an EC private key (P-256) in PEM format. You can generate one using `openssl`:
+
+```bash
+openssl ecparam -name prime256v1 -genkey -noout -out private-key.pem
+```
+
+### Signing with CLI
+
+Use the `--signing-key` flag to sign the CoRIM during generation.
+
+**SNP Example:**
+```bash
+cocos-cli policy create-corim snp \
+  --product Milan \
+  --signing-key private-key.pem \
+  --output signed-snp.corim
+```
+
+**TDX Example:**
+```bash
+cocos-cli policy create-corim tdx \
+  --signing-key private-key.pem \
+  --output signed-tdx.corim
+```
+
+### Verification
+
+The output file is a standard COSE_Sign1 message containing the CoRIM. It can be verified using any tool that supports COSE and CoRIM verification, such as the [veraison/corim](https://github.com/veraison/corim) library.
+
+## Output Format
+
+All commands output CoRIM in CBOR (Concise Binary Object Representation) format. By default, output is written to stdout, allowing for piping:
+
+```bash
+# Pipe to file
+cocos-cli policy create-corim snp --product Milan > policy.corim
+
+# Pipe to another command
+cocos-cli policy create-corim tdx | base64
+
+# Use --output flag
+cocos-cli policy create-corim snp --product Milan --output policy.corim
+```
+
+## Integration with Manager
+
+The manager service can dynamically generate CoRIM policies using the same underlying generator package. When `FetchAttestationPolicy` is called:
+
+1. For SNP: Calculates IGVM measurement using the `igvmmeasure` binary
+2. Extracts host data and launch TCB from VM configuration
+3. Generates CoRIM using the `generator` package
+4. Returns CBOR-encoded CoRIM
+
