# Dew Vault Secret Manager
Dew Vault is a secret manager for your projects. It helps you keep secrets out of
version control by storing each secret as an encrypted file under `.project/vault`.
Dew Vault stores project secrets as encrypted files under `.project/vault`.
By default the vault password is stored in `.project/secrets/dew.vault.password`.
## Config

run or stored in secret rotation metadata.
`generators` maps a generator name to a built-in generator definition. Values

Built-in generator types are resolved inside Dew, so secrets can be generated
without depending on host binaries.

### Rename a secret
`rename` changes a secret identifier while preserving value and metadata.
```bash
dew vault rename OLD_NAME NEW_NAME
dew vault rename OLD_NAME NEW_NAME --format json
dew vault rename --from OLD_NAME --to NEW_NAME
dew vault rename --from OLD_NAME --to NEW_NAME --format json
```
### Generate a secret value
`generate` runs a built-in generator without writing to the vault by default.
`generate` uses configured generators without writing to the vault by default.
```bash
dew vault generate postgres_password --length 64 --include_symbols
dew vault generate jwt_secret --bytes 64 --encoding base64
dew vault generate postgres_password --service payments --username app_user --format json
```
Pipe generated output directly into `set` when needed:
```bash
dew vault generate postgres_password --service payments | dew vault set DB_PASSWORD
dew vault generate --generator postgres_password --arg length=64 --arg include_symbols=true
dew vault generate --generator jwt_secret --arg bytes=64 --arg encoding=base64
dew vault generate --generator postgres_password --arg service=payments --arg username=app_user --format json
```
### Rotate secrets
`rotate` rewraps secrets with a new vault password when run without a name.
When run with a secret name, it rotates only that secret. For a secret with rotation
metadata (`rotation.enabled: true` and `rotation.generator`), Dew invokes that
configured built-in generator using the provided rotation values.
When run with a secret name, it rotates only that secret.
```bash
dew vault rotate
dew vault rotate <secret-name>
dew vault rotate <secret-name> --format json
dew vault rotate --name DB_PASSWORD
dew vault rotate --name DB_PASSWORD --format json
```
### Delete a secret
`delete` removes a secret and metadata from the vault.
```bash
dew vault delete <secret-name>
dew vault delete <secret-name> --format json
dew vault delete --name DB_PASSWORD
dew vault delete --name DB_PASSWORD --format json
```

## Status
This package is currently a scaffold/stub to establish the command and MCP
wiring. It does not yet implement full encrypted secret storage or rotation logic.
This package implements encrypted secret storage, rotation-aware metadata, and
command handlers exposed as MCP tools.
## Features
- Encrypted secret storage under `.project/vault` using AES-GCM + PBKDF2.
- Vault password stored at `.project/secrets/dew.vault.password` by default.
- Configurable generators for secret rotation in `dew.vault.generators`.
- Built-in generator-backed `generate` command.
- Metadata-aware rotation and metadata persistence for rotation policy configuration.
- Rotation support:
- `vault rotate` rotates the vault password and rewraps every secret.
- `vault rotate --name <name>` regenerates a single secret value (via metadata-defined
generator when available).
## Commands
- `dew vault init`
- `dew vault get`
- `dew vault set`
- `dew vault update`
- `dew vault rename`
- `dew vault rotate`
- `dew vault generate`
- `dew vault list`
- `dew vault delete`
Run `dew vault <command> --format json` for machine-friendly output.
## License
MIT — see [LICENSE](LICENSE).
## Example metadata
```yaml
rotation:
generator: postgres_password
length: 48
include_symbols: false
```
Store it with `--metadata` or `--metadata-file` on `dew vault set`/`dew vault update`.
