Hyperdrive now supports custom TLS/SSL certificates

Hyperdrive now supports more SSL/TLS security options for your database connections:

• Configure Hyperdrive to verify server certificates with verify-ca or verify-full SSL modes and protect against man-in-the-middle attacks
• Configure Hyperdrive to provide client certificates to the database server to authenticate itself (mTLS) for stronger security beyond username and password

Use the new wrangler cert commands to create certificate authority (CA) certificate bundles or client certificate pairs:

# Create CA certificate bundle
npx wrangler cert upload certificate-authority --ca-cert your-ca-cert.pem --name your-custom-ca-name

# Create client certificate pair
npx wrangler cert upload mtls-certificate --cert client-cert.pem --key client-key.pem --name your-client-cert-name

Then create a Hyperdrive configuration with the certificates and desired SSL mode:

npx wrangler hyperdrive create your-hyperdrive-config \
  --connection-string="postgres://user:password@hostname:port/database" \
  --ca-certificate-id <CA_CERT_ID> \
  --mtls-certificate-id <CLIENT_CERT_ID>
  --sslmode verify-full
