DevOps Guide

Automate certificate pin management in production environments using the TrustPin CLI. This guide covers the complete workflow for managing certificate pins from installation to automated CI/CD deployments.

Overview

TrustPin uses a two-step process for certificate pin updates:

Upsert: Add or update certificate pins in your project configuration
Sign: Cryptographically sign the configuration and publish it to the CDN

This separation allows you to:

Stage multiple pin changes before publishing
Review configuration changes before they go live
Maintain an audit trail of all pin modifications
Use different security controls for staging vs. publishing

Quick Start

1. Install the CLI

Homebrew (Recommended):


brew tap trustpin-cloud/trustpin-cli
brew install trustpin-cli

Direct Download (Linux x64 for CI/CD):


curl -L https://github.com/trustpin-cloud/homebrew-trustpin/releases/latest/download/trustpin-cli-linux-x64 -o trustpin-cli
chmod +x trustpin-cli
sudo mv trustpin-cli /usr/local/bin/

See Installation for platform-specific instructions.

2. Configure Authentication

Set the TRUSTPIN_API_TOKEN environment variable:


export TRUSTPIN_API_TOKEN="tp_your_token_here"

Get your Personal Access Token from TrustPin Console .

The CLI automatically uses this environment variable when available.

3. Get Your Project IDs


# List all projects
trustpin-cli projects list
 
# Get IDs in JSON format
trustpin-cli projects list --output json | jq -r '.data.projects[] | "\(.organization_id) \(.id) \(.name)"'

Note your Organization ID and Project ID for subsequent commands.

Certificate Pin Management Workflow

Step 1: Extract Pin from Certificate

Extract the SPKI SHA-256 fingerprint and expiration date from your certificate:


#!/bin/bash
CERT_FILE="cert.pem"
 
# Extract SPKI SHA-256 (OWASP recommended - pins the public key)
SPKI_SHA256=$(openssl x509 -in "$CERT_FILE" -pubkey -noout | \
  openssl pkey -pubin -outform der | \
  openssl dgst -sha256 -binary | \
  base64)
 
# Extract expiration date (portable across Linux/macOS)
EXPIRES_EPOCH=$(openssl x509 -in "$CERT_FILE" -noout -enddate | \
  cut -d= -f2 | \
  xargs -I{} date -jf "%b %d %H:%M:%S %Y %Z" "{}" +%s 2>/dev/null || \
  date -d "$(openssl x509 -in "$CERT_FILE" -noout -enddate | cut -d= -f2)" +%s)
EXPIRES=$(date -u -r "$EXPIRES_EPOCH" +%Y-%m-%dT%H:%M:%SZ 2>/dev/null || \
  date -u -d "@$EXPIRES_EPOCH" +%Y-%m-%dT%H:%M:%SZ)
 
echo "SPKI SHA-256: $SPKI_SHA256"
echo "Expires: $EXPIRES"

Example output:


SPKI SHA-256: oxVSdCLgthL3M5Vnnzepq8WWlkUfRPYkpjLpm+wn+1o=
Expires: 2026-04-13T08:37:02Z

Step 2: Upsert the Pin

Add or update the certificate pin in your project configuration:


trustpin-cli projects upsert \
  <organization-id> \
  <project-id> \
  --domain api.example.com \
  --pin spki-sha256:$SPKI_SHA256 \
  --expires $EXPIRES \
  --output json

Example output:


{
  "status": "success",
  "operation": "upsert",
  "domain": "api.example.com",
  "action": "added",
  "pin": {
    "type": "spki-sha256",
    "value": "oxVSdCLgthL3M5Vnnzepq8WWlkUfRPYkpjLpm+wn+1o=",
    "expires_at": "2026-04-13T08:37:02Z"
  },
  "config_version": {
    "before": 2,
    "after": 3
  }
}

Note: The configuration version increments, but changes are not yet published.

Step 3: Sign and Publish

Sign the configuration and publish it to the CDN:

Cloud-Managed Keys:


trustpin-cli projects sign \
  <organization-id> \
  <project-id> \
  --password <master-password>

Bring Your Own Key (BYOK):


trustpin-cli projects sign \
  <organization-id> \
  <project-id> \
  --private-key path/to/private-key.pem

Example output:


[1/5] Getting project information
  Project: Production API (Managed CDN with Cloud Keys)
[2/5] Loading project configuration
  Configuration loaded with 3 domains
[3/5] Preparing private key
  Using cloud-managed private key
[4/5] Creating and signing JWT
  JWT signed successfully
[5/5] Uploading signed configuration
✅ Configuration published successfully!

The signed configuration is now live and available to your mobile apps.

Complete Workflow Script

This script automates the entire process with error handling:


#!/bin/bash
set -e
 
ORG_ID="fb52418e-b5ae-4bff-b973-6da9ae07ba00"
PROJECT_ID="9caaea0a-013e-4e7b-80ea-cee6bfb52b36"
DOMAIN="api.example.com"
CERT_FILE="certs/api-cert.pem"
 
echo "═══ Step 1: Extract Pin from Certificate ═══"
SPKI_SHA256=$(openssl x509 -in "$CERT_FILE" -pubkey -noout | \
  openssl pkey -pubin -outform der | \
  openssl dgst -sha256 -binary | \
  base64)
 
# Extract expiration date (portable across Linux/macOS)
EXPIRES_EPOCH=$(openssl x509 -in "$CERT_FILE" -noout -enddate | \
  cut -d= -f2 | \
  xargs -I{} date -jf "%b %d %H:%M:%S %Y %Z" "{}" +%s 2>/dev/null || \
  date -d "$(openssl x509 -in "$CERT_FILE" -noout -enddate | cut -d= -f2)" +%s)
EXPIRES=$(date -u -r "$EXPIRES_EPOCH" +%Y-%m-%dT%H:%M:%SZ 2>/dev/null || \
  date -u -d "@$EXPIRES_EPOCH" +%Y-%m-%dT%H:%M:%SZ)
 
echo "  SPKI SHA-256: $SPKI_SHA256"
echo "  Expires: $EXPIRES"
 
echo ""
echo "═══ Step 2: Upsert Certificate Pin ═══"
RESULT=$(trustpin-cli projects upsert "$ORG_ID" "$PROJECT_ID" \
  --domain "$DOMAIN" \
  --pin "spki-sha256:$SPKI_SHA256" \
  --expires "$EXPIRES" \
  --output json)
 
echo "$RESULT" | jq '.'
 
# Verify success
STATUS=$(echo "$RESULT" | jq -r '.status')
if [ "$STATUS" != "success" ]; then
  echo "❌ Failed to upsert pin"
  exit 1
fi
 
ACTION=$(echo "$RESULT" | jq -r '.action')
echo "✅ Pin ${ACTION} successfully"
 
echo ""
echo "═══ Step 3: Sign and Publish Configuration ═══"
trustpin-cli projects sign "$ORG_ID" "$PROJECT_ID" \
  --password "$MASTER_PASSWORD"
 
echo ""
echo "✅ Certificate pin updated and published!"

Advanced Use Cases

Verifying Published Configuration

After signing and publishing, verify the configuration is correctly deployed to the CDN:


# Verify JWS signature using public key from CDN
trustpin-cli projects jws $ORG_ID $PROJECT_ID --verify
 
# Decode and inspect published configuration
trustpin-cli projects jws $ORG_ID $PROJECT_ID --decode
 
# Save published JWS for archival/compliance
trustpin-cli projects jws $ORG_ID $PROJECT_ID \
  --output-file "archive/config-$(date +%Y%m%d-%H%M%S).jws"

Why validation matters:

Confirms the sign command successfully published to CDN
Catches CDN propagation delays or failures
Provides audit trail of published configurations
Enables comparison between database and CDN state

Example validation script:


#!/bin/bash
set -e
 
ORG_ID="fb52418e-b5ae-4bff-b973-6da9ae07ba00"
PROJECT_ID="9caaea0a-013e-4e7b-80ea-cee6bfb52b36"
 
echo "Verifying published configuration..."
 
# Check if JWS is published
JWS=$(trustpin-cli projects jws $ORG_ID $PROJECT_ID 2>/dev/null)
if [ -z "$JWS" ]; then
  echo "❌ No JWS published on CDN"
  exit 1
fi
 
# Verify signature
if ! trustpin-cli projects jws $ORG_ID $PROJECT_ID --verify &>/dev/null; then
  echo "❌ JWS signature verification failed"
  exit 5
fi
 
echo "✅ JWS signature valid"
 
# Check version alignment
trustpin-cli projects jws $ORG_ID $PROJECT_ID --decode | grep -E "(Current DB Version|Published Version)"
 
echo "✅ Published configuration validated"

Self-Hosted CDN Deployment

For organizations hosting JWS configurations on their own infrastructure:

Workflow:

Use TrustPin to manage and sign configurations (upsert + sign)
Download the signed JWS from TrustPin CDN
Deploy to your own CDN/servers
Configure mobile SDKs to fetch from your infrastructure

Deployment script:


#!/bin/bash
set -e
 
ORG_ID="fb52418e-b5ae-4bff-b973-6da9ae07ba00"
PROJECT_ID="9caaea0a-013e-4e7b-80ea-cee6bfb52b36"
CDN_PATH="/var/www/cdn/trustpin"
 
echo "═══ Step 1: Upsert Certificate Pins ═══"
# Update your pins...
trustpin-cli projects upsert $ORG_ID $PROJECT_ID \
  --domain api.example.com \
  --pin spki-sha256:$SPKI_SHA256 \
  --expires $EXPIRES
 
echo ""
echo "═══ Step 2: Sign Configuration ═══"
trustpin-cli projects sign $ORG_ID $PROJECT_ID \
  --password "$MASTER_PASSWORD"
 
echo ""
echo "═══ Step 3: Download Signed JWS ═══"
trustpin-cli projects jws $ORG_ID $PROJECT_ID \
  --output-file "$CDN_PATH/config.jws"
 
echo ""
echo "═══ Step 4: Verify JWS Integrity ═══"
if ! trustpin-cli projects jws $ORG_ID $PROJECT_ID --verify; then
  echo "❌ JWS verification failed - aborting deployment"
  exit 5
fi
 
echo ""
echo "═══ Step 5: Deploy to CDN ═══"
# Example: Upload to S3, CloudFront, or your CDN
aws s3 cp "$CDN_PATH/config.jws" s3://your-bucket/trustpin/config.jws \
  --cache-control "public, max-age=3600" \
  --metadata "version=$(date +%s)"
 
# Invalidate CDN cache if needed
aws cloudfront create-invalidation \
  --distribution-id YOUR_DISTRIBUTION_ID \
  --paths "/trustpin/config.jws"
 
echo "✅ JWS deployed to self-hosted CDN"

Benefits:

Full control over CDN infrastructure and caching
Compliance with data residency requirements
Integration with existing CDN/monitoring systems
Custom cache invalidation strategies

AWS ACM: Automated Certificate Pinning on Renewal

When AWS Certificate Manager (ACM) automatically renews a certificate, this workflow detects the renewal via EventBridge, extracts the new certificate’s pins, upserts them into TrustPin, and signs/publishes the configuration using a BYOK private key stored in AWS Secrets Manager.

What happens on ACM renewal:

ACM renews the certificate (automatic, managed by AWS)
EventBridge detects the ACM Certificate Action event with ActionType: RENEWAL
Lambda is invoked automatically
Lambda exports the renewed certificate from ACM via the AWS SDK
Extracts the SPKI SHA-256 pin and expiration using openssl
Upserts the pin into TrustPin with trustpin-cli projects upsert
Signs and publishes the configuration using the BYOK private key with trustpin-cli projects sign --private-key
Mobile apps fetch the updated configuration from the CDN on their next refresh

Critical considerations:

⚠️ ACM Key Rotation: ACM generates new key pairs on every renewal (key reuse is not supported). This means the SPKI pin will change on every renewal. To prevent mobile app pinning failures:

Maintain dual pins: Keep both old and new certificate pins active during the transition period
Monitor app refresh cycles: Ensure sufficient overlap time for all active app instances to fetch the new configuration
Set appropriate overlap windows:
- Recommended: 7-14 days overlap between old and new pins for mobile apps
- Minimum: Consider your app’s usage patterns—if users don’t open the app for weeks, a longer overlap is critical
- Automated environments: For server-to-server or CI/CD deployments with guaranteed refresh cycles, shorter overlaps (hours to days) may be acceptable

Recommended dual-pin strategy:


# Before renewal (old cert expires in 30 days)
# Old pin: expires 2026-03-01
# Status: Active
 
# After renewal detected (new cert issued)
# Old pin: expires 2026-03-01 (keep active)
# New pin: expires 2027-03-01 (newly added)
# Status: Both active for 30 days
 
# After old cert expires (2026-03-01)
# New pin: expires 2027-03-01
# Status: Old pin automatically ignored by SDKs

This ensures zero downtime during certificate renewals and accounts for mobile apps that haven’t fetched the updated configuration yet.

Troubleshooting

Authentication Issues

Problem: HTTP 401 Unauthorized

Solutions:


# Verify token is set correctly
echo $TRUSTPIN_API_TOKEN
 
# Test authentication
trustpin-cli projects list --output json
 
# Reconfigure CLI
trustpin-cli configure

In CI/CD:

Verify TRUSTPIN_API_TOKEN secret is set correctly
Ensure token hasn’t expired (create new token if needed)
Check token has access to the organization/project

Validation Errors

Problem: Invalid pin format or type


❌ Validation failed: invalid pin type: sha255
Valid types: sha256, sha512, spki-sha256, spki-sha512

Solution: Fix typo in pin type (e.g., sha255 → sha256)

Problem: Invalid base64 encoding


❌ Validation failed: invalid base64 encoding in pin value

Solution: Ensure hash is base64-encoded, not hex:


# Correct: base64 encoding
openssl dgst -sha256 -binary | base64
 
# Incorrect: hex encoding
openssl dgst -sha256

Problem: Wrong hash length


❌ Validation failed: invalid sha256 hash length: expected 32 bytes, got 16 bytes

Solution: Verify you’re hashing the correct data:


# For SPKI pins (correct)
openssl x509 -in cert.pem -pubkey -noout | \
  openssl pkey -pubin -outform der | \
  openssl dgst -sha256 -binary | base64
 
# For certificate pins (correct)
openssl x509 -in cert.pem -outform der | \
  openssl dgst -sha256 -binary | base64

Private Key Issues (BYOK)

Problem: Failed to decrypt private key


❌ Failed to decrypt private key: cipher: message authentication failed

Solutions:

Verify master password is correct for cloud-managed keys
Verify private key password is correct for BYOK
Check private key file is in PEM format: file private-key.pem

Problem: Private key format errors in CI/CD


# Verify key is properly decoded
file private-key.pem
# Should show: "PEM RSA private key" or similar
 
# Check file permissions
ls -la private-key.pem
# Should be 600 or 400

Network Issues

Problem: Connection timeout or network errors

Solutions:


# Test API connectivity
curl -H "Authorization: Bearer $TRUSTPIN_API_TOKEN" \
  https://api.trustpin.cloud/users
 
# Check API base URL
echo $TRUSTPIN_API_BASE_URL
 
# Use verbose mode for debugging
trustpin-cli projects sign <org-id> <project-id> --verbose

Upsert Operation Issues

Problem: Upsert succeeds but nothing changes

Reason: The pin already exists with the same expiration (idempotent operation)

Response:


{
  "status": "success",
  "operation": "upsert",
  "action": "no_change",
  "message": "Pin already exists with same expiration"
}

Solution: This is expected behavior. No action needed.

Exit Codes

The CLI uses standard exit codes for automation:

Code	Meaning	Example
0	Success or no-op	Pin added/updated, or already exists
2	API error	401, 404, 500 HTTP errors
4	Validation error	Invalid domain, pin format, or type
99	Unexpected error	Network timeout, file I/O error

Use in scripts:


if ! trustpin-cli projects upsert ... --output json > result.json; then
  EXIT_CODE=$?
  echo "❌ Upsert failed with exit code $EXIT_CODE"
  cat result.json
  exit $EXIT_CODE
fi
