Parameter

Argument Type Definition and Requirements

secret

String

The secret identifying an existing key or token.

Returns

An object containing data returned by performing a lookup for the secret. If the secret does not match an existing key or token, an error is returned.

When the secret string identifies a key, the object has the following fields:

Field Name Field Type Definition and Requirements

ref

Reference

The reference identifies the key that was retrieved.

ts

Integer

The timestamp, with microsecond resolution, reporting the most recent modification time of the key.

database

Reference

A reference to the database the key is protecting.

role

String

The security role for this key.

hashed_secret

String

The hash of the secret.

When the secret string identifies a token, the object has the following fields:

Field Name Field Type Definition and Requirements

ref

Reference

The reference identifies the token instance that was retrieved.

ts

Integer

The timestamp, with microsecond resolution, reporting the most recent modification of the token.

instance

Reference

A reference to the document representing the logged-in user (the one passed to the Login function invocation that created the token.)

hashed_secret

String

A hash of the secret. The secret is not recoverable from this value.

Examples

The following query retrieves a key by providing a given secret:

client.Query(
  KeyFromSecret("fnAChGwBcAACAO70ziE0cfROosNJHdgBmJU1PgpL"));
