This page documents an earlier version of InfluxDB OSS.[InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a
copy of the database file doesn’t expose usable tokens. Existing
tokens are hashed on first startup and the original strings can’t
be recovered afterward — **capture any plaintext tokens you still
need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

Flux is InfluxData’s functional data scripting language designed for querying,
analyzing, and acting on data.

These guides walks through important concepts related to Flux and querying time
series data from InfluxDB using Flux.

## Tools for working with Flux

The [Execute queries](/influxdb/v2/query-data/execute-queries) guide walks through
the different tools available for querying InfluxDB with Flux.

## Before you start

To get a basic understanding of the Flux data model and syntax, see[Get started with Flux](/flux/v0/get-started/) in the[Flux documentation](/flux/v0/).
