A GPG keypair stores an ASCII-armoured GPG public key and private key pair. Both halves are encrypted at rest and delivered to your containers as separate files.

When to use a GPG keypair

  • Your application signs artifacts, packages, or commits with a GPG key
  • You verify signatures produced by a third party and need the public key on disk
  • A release pipeline signs container images or SBOMs before publishing
  • You encrypt or decrypt data at the application layer using GPG

What Bahriya stores

When you upload a GPG keypair, Bahriya parses it and stores metadata alongside the encrypted material:

FieldDescription
Key IDThe short key ID extracted from the public key
FingerprintFull fingerprint for verification
AlgorithmKey algorithm (RSA, DSA, EdDSA, etc.) and key size
User IDThe UID embedded in the key (e.g. deploy@example.com)
ExpiresKey expiry date, shown as a countdown badge in the console

This metadata is visible in list views and detail pages so you can spot expiring keys at a glance.

Mounting in containers

When you attach a GPG keypair to a container, you choose a mount path. The key files appear as:

<mount-path>/public_key    # The public key (ASCII-armoured)
<mount-path>/private_key   # The private key (ASCII-armoured)

Your application reads them from these paths. For example, a signing service might reference /etc/gpg/public_key and /etc/gpg/private_key.

Rotation

Rotation creates a new version of the keypair. The previous version is retained for rollback. After rotation:

  • File-mounted containers pick up the new keys automatically within about 60 seconds. No manual action needed.
  • If you need to force a restart, use the Redeploy button on the Consumers panel.

Pricing

GPG keypairs are billed at $0.02 per month while they exist, plus $0.02 per region per month when attached to a project.
