+
+### Azure TDX Attestation
+
+When the agent runs on an Azure TDX CVM, Azure attestation uses the direct Azure TDX flow. The agent writes TDX report data to Azure HCL vTPM storage, reads the refreshed HCL report, requests a TD quote from Azure IMDS, and submits the quote plus HCL runtime data to Microsoft Azure Attestation. This path does not depend on Confidential Containers attestation-agent `GetEvidence` or KBS token retrieval.
+
+`AGENT_MAA_URL` selects the Microsoft Azure Attestation endpoint. `AZURE_TDX_IMDS_URL` can override the Azure IMDS TDX quote endpoint, and `AZURE_HCL_REFRESH_WAIT` controls the wait used to avoid reading a stale HCL report after report-data is written.
+
+### Remote Resource Download (Optional)
+
+The agent supports downloading encrypted algorithms and datasets from remote registries (S3, HTTP/HTTPS) and retrieving decryption keys from a Key Broker Service (KBS) via attestation.

+                                             (Key Broker)
+```
+
+## 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_}")
+EOF
+
+# 2. Create requirements.txt
+cat > requirements.txt << 'EOF'
+pandas
+scikit-learn
+EOF
+
+# 3. Create a Dockerfile
+cat > Dockerfile << 'EOF'
+FROM python:3.9-slim
+RUN pip install pandas scikit-learn
+COPY lin_reg.py /app/algorithm.py
+COPY requirements.txt /app/requirements.txt
+WORKDIR /app
+ENTRYPOINT ["python", "algorithm.py"]
+EOF
+
+# 4. Build the image
+docker build -t localhost:5000/lin-reg-algo:v1.0 .
+docker push localhost:5000/lin-reg-algo:v1.0
+
+# 5. Generate and store key
+openssl rand -out algo.key 32
+
+# 6. Store key in KBS using kbs-client
+../target/release/kbs-client --url http://localhost:8080 config \
+  --auth-private-key kbs-admin.key \
+  set-resource \
+  --path default/key/algo-key \
+  --resource-file algo.key
+
+# 7. Encrypt the image using Host Skopeo + Docker Keyprovider
+# Start Keyprovider in background
+docker run -d --rm --name keyprovider --network host \
+  -v "$PWD:/work" -w /work \

+
+## 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 $NF}')
+
+DATASET_HASH=$(./build/cocos-cli checksum iris.csv 2>&1 | awk '{print $NF}')
+
+go build -o build/cvms-test ./test/cvms/main.go
+HOST=$HOST_IP PORT=7001 ./build/cvms-test \
+  -public-key-path ./public.pem \
+  -attested-tls-bool false \
+  -algo-type python \
+  -algo-source-url docker://$HOST_IP:5000/encrypted-lin-reg:v1.0 \
+  -algo-kbs-path default/key/algo-key \
+  -algo-kbs-url http://$HOST_IP:8080 \
+  -algo-hash $ALGO_HASH \
+  -algo-args datasets/dataset_0.csv \
+  -dataset-source-urls docker://$HOST_IP:5000/encrypted-iris:v1.0 \
+  -dataset-kbs-paths default/key/dataset-key \
+  -dataset-kbs-urls http://$HOST_IP:8080 \
+  -dataset-hash $DATASET_HASH
+```
+
+> [!NOTE]
+> You must specify the KBS URL for each encrypted resource using `-algo-kbs-url` and `-dataset-kbs-urls`. A global KBS is no longer supported.
+
+
+### 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",
+    "kbs": {
+      "url": "http://192.168.100.15:8080",
+      "enabled": true
+    }
+  },
+  "datasets": [
+    {
+      "filename": "iris.csv",
+      "source": {
+        "type": "oci-image",
+        "url": "docker://localhost:5000/encrypted-iris:v1.0",
+        "encrypted": true,
+        "kbs_resource_path": "default/key/dataset-key"
+      },
+      "kbs": {
+        "url": "http://192.168.100.20:8080",
+        "enabled": true
+      }
+    }
+  ],
+  "kbs": {
+    "url": "http://192.168.100.15:8080",
+    "enabled": true
+  }
+}
+```
+
+## 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
+```
+
+## 4. Testing with Non-OCI Sources (S3, HTTP, GCS)
+
+The `cvms` test utility also supports testing remote encrypted resources hosted in more traditional environments like S3-compatible storage or simple web servers, bypassing the need for container registries and OCI images.
+
+### Supported Flags
+
+The following flags define how resources should be fetched:
+
+- `--algo-source-url`: The URL of the algorithm (e.g. `s3://bucket/algo.bin`, `https://server/algo.bin`)
+- `--algo-source-type`: The type of remote endpoint (`s3`, `gcs`, `https`, `http`). If omitted, it will automatically be inferred from the URL scheme.
+- `--algo-kbs-path`: The KBS path to retrieve the AES-256-GCM key from. If present, the agent will attempt decryption.
+- `--dataset-source-urls` and `--dataset-source-type`: Defines the locations and protocols for datasets.
+
+### Encryption Format for Non-OCI Sources
+
+Unlike OCI images where `ocicrypt` wraps the dataset, resources hosted on HTTP/S3 must be straightforwardly encrypted using **AES-256-GCM**.
+
+The expected format is exactly as produced by standard Go AES-GCM:
+`nonce (12 bytes) || ciphertext || tag`
+
+### Test Example
+
+If you had a Python script encrypted using a key hosted at KBS path `default/my-keys/python-script` and uploaded to `s3://my-secure-bucket/script.enc`, you could run:
+
+```bash
+cd test
+go run cvms/main.go --algo-source-url="s3://my-secure-bucket/script.enc" \
+                    --algo-source-type="s3" \
+                    --algo-kbs-path="default/my-keys/python-script" \
+                    --algo-type="python" \
+                    --public-key-path=./test-data/public-key.pem
+```
+
+The system will:
+1. Connect via `attestation-agent` to the KBS to retrieve the symmetric key
+2. Use Google Cloud Storage client library methods (support for generic S3 via environment variables is standard) to fetch the resource
+3. Decrypt using AES-256-GCM
+4. Run the code normally

+# 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
