# Insecure

A container for older, cryptographically insecure algorithms.

## Declaration

```swift
enum Insecure
```

## Overview

Overview important: These algorithms aren’t considered cryptographically secure, but the framework provides them for backward compatibility with older services that require them. For new services, avoid these algorithms.
