# Permits

## Query Permits

Query permits are an alternative querying method introduced in the SNIP-24 design specification. Query permits use of a cryptographic technique known as public-key encryption coupled with digital signatures.

A permit is a formatted message, it outlines several arguments such as what tokens the permit applies to and what permissions the permit should allow (e.g. should the permit allow the querier to view a user’s transaction history, balance, etc.). Permits are not saved in the smart contract state and do not require the initiation of a blockchain transaction. Therefore, permits are a less permanent way of gaining viewing access with less network strain.

## Signing Permits

Users can sign permits with their account’s private key to give certain dApps or parties viewing access to specific parts of their private data for a specified amount of time. To get viewing access a user sends a query, with the signed permit as an argument, to a smart contract. Once received, the smart contract, using the user’s public key, can validate the identity based on the signature the user provided. If the user’s identity is confirmed, the smart contract returns the data as requested.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.scrt.network/secret-network-documentation/development/development-concepts/secret-contract-fundamentals/access-control/permits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
