# Signs a release (docs/release-flow.md, "Signed checksums"): writes SHA256SUMS for the files given, then
|
|
# SHA256SUMS.sig beside them, one base64 Ed25519 signature per line over "horizon release <tag>\n" + SHA256SUMS,
|
|
# for every key set in RELEASE_SIGNING_KEY and RELEASE_SIGNING_KEY_NEXT (base64 PKCS#8, the `release`
|
|
# environment's secrets). The job that runs this holds the private keys, so it runs nothing from the repository
|
|
# but this file, which calls only the runner's sha256sum and OpenSSL; the publish job then checks the result
|
|
# with horizon-release-sign, as launchers do.
|
|
# EPHEMERAL=yes (dry runs) signs with a throwaway key instead and writes its public key to ephemeral.pub.
