// gen-release-key generates an ed25519 keypair for signing release artifacts.
|
||
|
|
// Run once per repository, then store the printed values:
|
||
|
|
//
|
||
|
|
// RELEASE_SIGNING_KEY → GitHub Actions secret (private key, base64)
|
||
|
|
// RELEASE_SIGNING_PUBKEY → GitHub Actions variable (public key, base64)
|
||
|
|
//
|
||
|
|
// The public key is injected into the binary at build time via the
|
||
|
|
// goreleaser ldflags entry that resolves
|
||
|
|
// `github.com/torrentclaw/unarr/internal/upgrade.releasePubKeyBase64`.
|
||
|
|
// The private key is used by the workflow's "Sign checksums.txt" step.
|

|
|
//

// Build and run:
|
||
|
|
//
|

// go run ./scripts/gen-release-key
