# Stella Ops Release {{VERSION}} - Verification Guide
|
||||
|
||||
This bundle contains everything needed to verify the authenticity and integrity
|
||||
of Stella Ops release {{VERSION}} in an air-gapped environment.
|
||||
|
||||
## Quick Verification (requires cosign)
|
||||
|
||||
```bash
|
||||
./verify.sh
|
||||
```
|
||||
|
||||
Or on Windows (PowerShell 7+):
|
||||
|
||||
```powershell
|
||||
./verify.ps1
|
||||
```
|
||||
|
||||
## Manual Verification
|
||||
|
||||
### 1. Verify Checksums
|
||||
|
||||
Verify all artifacts match their expected checksums:
|
||||
|
||||
```bash
|
||||
cd artifacts/
|
||||
sha256sum -c ../checksums/SHA256SUMS
|
||||
```
|
||||
|
||||
On Windows:
|
||||
```powershell
|
||||
Get-Content ..\checksums\SHA256SUMS | ForEach-Object {
|
||||
$parts = $_ -split '\s+', 2
|
||||
$expected = $parts[0]
|
||||
$file = $parts[1]
|
||||
$computed = (Get-FileHash -Path $file -Algorithm SHA256).Hash.ToLower()
|
||||
if ($computed -eq $expected) {
|
||||
Write-Host "[PASS] $file" -ForegroundColor Green
|
||||
} else {
|
||||
Write-Host "[FAIL] $file" -ForegroundColor Red
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Verify Checksums Signature (requires cosign)
|
||||
|
||||
Verify that the checksums file was signed by Stella Ops:
|
||||
|
||||
```bash
|
||||
cosign verify-blob \
|
||||
--key cosign.pub \
|
||||
--signature checksums/SHA256SUMS.sig \
|
||||
checksums/SHA256SUMS
|
||||
```
|
||||
|
||||
### 3. Verify Individual Artifact Signatures
|
||||
|
||||
```bash
|
||||
# For each artifact
|
||||
cosign verify-blob \
|
||||
--key cosign.pub \
|
||||
--signature artifacts/stella-{{VERSION}}-linux-x64.tar.gz.sig \
|
||||
artifacts/stella-{{VERSION}}-linux-x64.tar.gz
|
||||
```
|
||||
|
||||
### 4. Verify Provenance (SLSA)
|
||||
|
||||
Verify that the SLSA provenance statement was signed and inspect its contents:
|
||||
|
||||
```bash
|
||||
# Verify signature
|
||||
cosign verify-blob \
|
||||
--key cosign.pub \
|
||||
--signature provenance/stella-cli.slsa.intoto.jsonl.sig \
|
||||
provenance/stella-cli.slsa.intoto.jsonl
|
||||
|
||||
# Inspect provenance contents
|
||||
cat provenance/stella-cli.slsa.intoto.jsonl | jq .
|
||||
```
|
||||
|
||||
The provenance should show:
|
||||
- **Builder ID**: `https://ci.stella-ops.org/builder/v1`
|
||||
- **Source commit**: `{{SOURCE_COMMIT}}`
|
||||
- **Build timestamp**: Matches release time
|
||||
- **Materials**: Lists all build inputs with digests
|
||||
|
||||
### 5. Verify SBOMs
|
||||
|
||||
```bash
|
||||
# Verify SBOM signature
|
||||
cosign verify-blob \
|
||||
--key cosign.pub \
|
||||
--signature sbom/stella-cli.cdx.json.sig \
|
||||
sbom/stella-cli.cdx.json
|
||||
|
||||
# Inspect SBOM (requires jq or any JSON viewer)
|
||||
cat sbom/stella-cli.cdx.json | jq '.components | length'
|
||||
```
|
||||
|
||||
## Transparency Log Verification (requires network)
|
||||
|
||||
If you have network access, you can verify the artifacts were recorded in the
|
||||
Rekor transparency log:
|
||||
|
||||
```bash
|
||||
rekor-cli verify \
|
||||
--artifact artifacts/stella-{{VERSION}}-linux-x64.tar.gz \
|
||||
--signature artifacts/stella-{{VERSION}}-linux-x64.tar.gz.sig \
|
||||
--public-key cosign.pub
|
||||
```
|
||||
|
||||
### Rekor Log Entries
|
||||
|
||||
The following Rekor log entries are associated with this release:
|
||||
|
||||
{{REKOR_ENTRIES}}
|
||||
|
||||
You can look up any entry:
|
||||
|
||||
```bash
|
||||
rekor-cli get --uuid <UUID>
|
||||
```
|
||||
|
||||
## Offline Rekor Proof Verification
|
||||
|
||||
If Rekor proofs are included in this bundle (in `rekor-proofs/`), you can verify
|
||||
Merkle inclusion proofs without network access:
|
||||
|
||||
```bash
|
||||
# Verify inclusion proof (advanced)
|
||||
# See: https://docs.sigstore.dev/verification/offline/
|
||||
```
|
||||

||||

||||
Install cosign:
|
||||
- macOS: `brew install cosign`
|
||||
- Linux: Download from https://github.com/sigstore/cosign/releases
|
||||
- Windows: Download from https://github.com/sigstore/cosign/releases
|
||||
|
||||
### "Error: no matching signatures"
|
||||
|
||||
Ensure you're using the `cosign.pub` file from this bundle, not a different key.
|
||||
|
||||
### Checksum mismatch
|
||||
|
||||
If checksums don't match:
|
||||
1. Re-download the artifact
|
||||
2. Verify the download completed successfully
|
||||
3. Check for file corruption during transfer
|
||||
|
||||
### Certificate verification failed
|
||||
|
||||
For keyless-signed artifacts, you may need to specify the expected identity:
|
||||
|
||||
```bash
|
||||
cosign verify-blob \
|
||||
--certificate-identity "https://ci.stella-ops.org" \
|
||||
--certificate-oidc-issuer "https://oauth2.sigstore.dev/auth" \
|
||||
--signature artifact.sig \
|
||||
artifact
|
||||
```
