Key vaults

The full guide is at Vaults. Two keys configure them.

key_vaults

• Type: list[dict]  ·  Default: []

An ordered list of key-vault backends. unshackle queries them in order and reuses the content keys instead of licensing them again. Each entry needs a type (the backend module name) and a name, plus backend-specific keys.

type	Purpose	Required keys	Notes
SQLite	Local SQLite database	name, path	Loaded critically; a failure aborts the run.
MySQL	Remote MySQL database	name, host, database, username	Extra keys (e.g. password, port) forwarded to pymysql. connect_timeout defaults to vault_timeout.
API	RESTful JSON API	name, uri, token	Optional headers map is sent with every request. Honours vault_timeout.
HTTP	HTTP API with modes	name, host, one of password/api_key, and username in query mode	api_mode: query (default), json, decrypt_labs. Honours vault_timeout.

key_vaults:
  - type: SQLite
    name: Local
    path: ~/.unshackle/keys.db
  - type: MySQL
    name: Team
    host: db.example.com
    database: keys
    username: unshackle
    password: hunter2
    no_push: false

!!! note "Per-entry options" - no_push: true makes a vault read-only (unshackle fetches content keys from it but never writes to it). - A vault of type: API whose name contains decrypt_labs auto-fills its token from decrypt_labs_api_key when not set inline. Vault type values are case-sensitive module names. - unshackle treats an all-zero content key (32 zeros) as "no key" everywhere and never stores it.

!!! note "Bad content keys" A content key from a vault is proven by a short FFmpeg decode of the decrypted output. A content key that fails the decode is written to the bad_keys table of every SQLite vault with the name of the vault that supplied it, and every vault lookup skips a flagged pair from then on. Only the SQLite backend stores flags. A serve instance with server_cdm flags a pair the same way when a remote client reports it, so a server whose key_vaults hold no SQLite entry cannot remember a bad content key.

vault_timeout

• Type: float  ·  Default: 10.0

Timeout in seconds for vault operations. Injected automatically into any backend whose constructor accepts a timeout parameter (a per-vault timeout still wins). The MySQL backend uses it as the default connect_timeout.
