# fonts.verifyIntegrity

Part of [Fonts](https://kernstra.com/docs/web-sdk/config/fonts) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `boolean`
- Default: `true`
- Page: https://kernstra.com/docs/web-sdk/config/fonts/verifyintegrity

SHA-256 verify downloaded bundled fonts. Downloads from the store are always verified. `false` is only needed when self-hosting _modified_ font files under the same ids via `fontsBaseUrl`; exact copies of the original files pass verification.
