# SHSignature

An object that contains the opaque data and other information for a signature.

## Declaration

```swift
class SHSignature
```

## Overview

Overview You can save signatures to files and share them with others. Use saved signatures to populate a custom catalog. Check whether your captured query signature is long enough to search for a match by comparing duration to the minimumQuerySignatureDuration and maximumQuerySignatureDuration of a catalog. For signatures longer than maximumQuerySignatureDuration, use slices(from:duration:stride:) to create multiple segments that meet the duration requirement.
