unkinben e7dda4bcda Add GPG/OpenPGP secrets engine 
Provide a transit-style Vault/OpenBao secrets engine whose key material is
OpenPGP, so services can sign/verify/encrypt/decrypt with GPG keys that never
leave the barrier — and so tools like pass can encrypt to an exported public
key while delegating decryption back to Vault.

- Add versioned key management (keys/<name> CRUD+list, config, rotate, import)
  with private material seal-wrapped under key/ and per-key locking.
- Add sign/verify (detached OpenPGP) and encrypt/decrypt paths; decrypt
  auto-detects armored vs raw-binary ciphertext (what pass/gpg write).
- Add export/<public-key|private-key>/<name>; public always exportable,
  private only when the key is marked exportable.
- Use ProtonMail go-crypto for OpenPGP; support rsa-2048/3072/4096 and ed25519.
- Clone the sibling plugin's build/packaging/CI: dual-target RPMs
  (vault + openbao plugin dirs), Woodpecker PR/release pipelines, and a
  Vault+OpenBao e2e harness. Unit tests include real gpg and pass interop.

# vault-plugin-secrets-gpg # vault-plugin-secrets-gpg
HashiCorp Vault / OpenBao secrets engine for GPG/OpenPGP keys (sign/verify/encrypt/decrypt, transit-style versioned keys, pass-compatible) A HashiCorp Vault / OpenBao secrets engine that manages **GPG / OpenPGP keys**
and performs **signing, verification, encryption and decryption** with them —
the transit engine, but the key material is OpenPGP.
Keys are generated and stored inside Vault's own barrier storage (seal-wrapped
under `key/`) and the private key never leaves Vault unless a key is explicitly
marked `exportable`. Each named key is **versioned**: rotating adds a new
OpenPGP entity, while older versions are retained so archived signatures still
verify and old ciphertext still decrypts.
The armored public key the engine hands back is a standard, importable OpenPGP
key, so `gpg`, [`pass`](https://www.passwordstore.org/) and friends can encrypt
to it while the private key stays in Vault and decryption is delegated back to
`decrypt/<name>`.
```
gpg / pass ──encrypt to public key──▶ binary .gpg
│ │
│ import public key │ decrypt/<name>
▼ ▼
export/public-key/<name> ◀── Vault ──▶ private key (never leaves the barrier)
```
## Paths
| Path | Purpose |
|------|---------|
| `keys/<name>` (write/read/delete, list `keys/`) | generate a key (`rsa-2048`, `rsa-3072`, `rsa-4096`, `ed25519`); read metadata + armored public key |
| `keys/<name>/config` | set `min_decryption_version`, `deletion_allowed`, `exportable` |
| `keys/<name>/rotate` | add a new version (older versions kept for decrypt/verify) |
| `keys/<name>/import` | import an existing armored private key |
| `export/<public-key\|private-key>/<name>[/<version>]` | export armored key material |
| `sign/<name>` / `verify/<name>` | detached OpenPGP signature over base64 input |
| `encrypt/<name>` / `decrypt/<name>` | OpenPGP encrypt to / decrypt with the key |
Creating a key is **idempotent** — writing `keys/<name>` again returns the
existing key rather than regenerating it. Deletion is refused unless
`deletion_allowed=true` is set via `keys/<name>/config`.
## Usage
```sh
# register + enable (the plugin_directory must contain the binary)
sha=$(sha256sum /opt/vault-plugins/vault-plugin-secrets-gpg | cut -d' ' -f1)
vault plugin register -sha256=$sha secret vault-plugin-secrets-gpg
vault secrets enable -path=gpg vault-plugin-secrets-gpg
# generate a key
vault write gpg/keys/app algorithm=rsa-4096 identity="App <app@unkin.net>"
vault read gpg/keys/app # metadata + armored public key
# sign / verify (input and output are base64 / armored)
sig=$(vault write -field=signature gpg/sign/app input=$(base64 <<<"ship it"))
vault write -field=valid gpg/verify/app input=$(base64 <<<"ship it") signature="$sig"
# encrypt / decrypt
ct=$(vault write -field=ciphertext gpg/encrypt/app plaintext=$(base64 <<<"secret"))
vault write -field=plaintext gpg/decrypt/app ciphertext="$ct" | base64 -d
# rotate; old ciphertext still decrypts
vault write gpg/keys/app/rotate
```
## Using it with `pass`
The engine holds the private key; `pass`/`gpg` only need the **public** key to
encrypt, and delegate decryption back to Vault.
```sh
# import the engine's public key into your gpg keyring
vault read -field=public_key gpg/keys/app | gpg --import
fpr=$(vault read -field=fingerprint gpg/keys/app)
# initialise a password store against it
pass init "$fpr"
pass insert email/example # writes ~/.password-store/email/example.gpg (binary OpenPGP)
# decrypt an entry through Vault (decrypt accepts binary ciphertext directly)
vault write -field=plaintext gpg/decrypt/app \
ciphertext=$(base64 -w0 ~/.password-store/email/example.gpg) | base64 -d
```
`decrypt/<name>` auto-detects ASCII-armored vs raw-binary input, so the binary
`.gpg` files `pass` writes work without conversion. A thin `gpg`/`pass`
wrapper that routes decryption to Vault automatically can be layered on top.
## Build
```sh
make build # -> dist/vault-plugin-secrets-gpg
make test lint # go test -race / go vet
make e2e # full lifecycle against Vault + OpenBao in Docker
make rpm # vault + openbao RPM flavours
```
CI (Woodpecker) runs pre-commit/build/lint/test on PRs and builds+publishes the
RPMs on a `v*` tag. The unit tests include real-`gpg` and real-`pass` interop
checks (skipped automatically when those binaries are absent).
