## Encryption

In this topic, various flexible encryption methods such as **full-site encryption** and **partial encryption** are supported.

::: warning Note
Due to the limitations of `vuepress` as a static site, **encryption** only makes the content *appear* invisible.
During compilation, the content is not pre-rendered into the `html`,
but it can still be retrieved from the site's source files.
Therefore, the **encryption** feature should not be considered as completely secure or reliable.

Avoid using the **encryption feature** for content that requires **strict confidentiality**.
:::

**Unlocked articles are only visible during the current session.**

## Enabling Encryption

Add the `encrypt` option in the theme configuration.

```ts title=".vuepress/config.ts"
import { defineUserConfig } from 'vuepress'
import { plumeTheme } from 'vuepress-theme-plume'

export default defineUserConfig({
  theme: plumeTheme({
    encrypt: {
      // more options...
    }
  })
})
```

## Full-Site Encryption

In some cases, you may need to encrypt the entire site.
You can configure full-site encryption using the `encrypt.global` option and set one or more passwords with `encrypt.admin`.

```ts title=".vuepress/config.ts"
export default defineUserConfig({
  theme: plumeTheme({
    encrypt: {
      global: true,
      admin: ['123456'],
    }
  })
})
```

## Partial Encryption

In most cases, you may only need to encrypt a specific article, directory, etc.
You can configure partial encryption using the `encrypt.rules` option.

```ts title=".vuepress/config.ts"
export default defineUserConfig({
  theme: plumeTheme({
    encrypt: {
      rules: {
        // Can be the relative path of an MD file to encrypt that file
        'frontend/basics.md': '123456',
        // Can be a directory path to encrypt all articles under that directory
        '/notes/vuepress-theme-plume/': '123456',
        // Can be a request path to encrypt all articles under that path
        '/vuepress-theme-plume/': '123456',
        // Can be a specific page's request path to encrypt that page
        '/article/f8dnci3/': '123456',
        // If prefixed with `^`, pages matching the regex will also be encrypted
        '^/(a|b)/': '123456',
      }
    }
  })
})
```

The **key** in `encrypt.rules` serves as the matching rule,
and the **value** is the corresponding password (or multiple passwords) for that rule.

:::tip Notes

- Passwords must be plain strings.
- If encrypting an entire directory, unlocking applies to the entire directory, not individual articles within it.
- `encrypt.admin` can also be used to unlock **partially encrypted** pages.
- After unlocking with `encrypt.admin`, the user is considered an admin, and all other locked pages are unlocked by default.

### Frontmatter

In the `Frontmatter` of a Markdown file, you can set the article's password using the `password` field.

```md
---
title: Encrypted Article
password: 123456
---
```

You can also add the `passwordHint` option to provide a password hint.

```md
---
title: Encrypted Article
password: 123456
passwordHint: The password is 123456
---
```

## Example

Click to visit [Encrypted Article, Password: 123456](/article/enx7c9s/)

## Partial Content Encryption

### Configuration

Partial content encryption is implemented through the `::: encrypt` container. You need to configure the `markdown.encrypt` option:

```ts title=".vuepress/config.ts"
export default defineUserConfig({
  theme: plumeTheme({
    markdown: {
      encrypt: true, // [!code ++]
    }
  })
})
```

You can also set a unified default password for the `::: encrypt` container:

```ts title=".vuepress/config.ts"
export default defineUserConfig({
  theme: plumeTheme({
    markdown: {
      encrypt: {
        password: 123456, // [!code ++]
      }
    }
  })
})
```

### Usage

Use the `::: encrypt` container to wrap the content that needs to be encrypted.
You can add `password` / `pwd` attribute to the container to set the password for that container.
If no password is set, the default password will be used.

You can also add a `hint` attribute to set a password hint.

```md /password="123456"/
::: encrypt password="123456" hint="The password is 6 consecutive digits"
This is encrypted content
:::
```

::: info Only one password is effective; multiple passwords are not supported simultaneously.
:::

### Example

**Input:**

```md
::: encrypt password="123456"
This is encrypted content
:::
```

**Output:**

::: encrypt password="123456"
This is encrypted content
:::

**Input:**

```md
::: encrypt password="654321" hint="The password is 6 consecutive digits"
This is encrypted content 2
:::
```

**Output:**

::: encrypt password="654321" hint="The password is 6 consecutive digits"
This is encrypted content 2
:::

::: warning Usage Limitations
**For encrypted content, you can use:**

- All standard markdown syntax
- Most extended syntax provided by the theme, except:
  - `@[demo]()` code examples imported from directories
  - `@[code]()` code snippets imported from directories
  - `@[code-tree]()` code trees imported from directories
- Global Vue components provided by the theme
- User-defined global Vue components
- Encrypted content cannot contain executable scripts; for special interactions, please implement through components.

**Network Environment Requirements:**
Partial content encryption is implemented using [Crypto API](https://developer.mozilla.org/en-US/docs/Web/API/Crypto),
therefore, it will not work properly in **non-HTTPS environments**.
:::

::: details If you are a technical developer, you may need to know

The original markdown content is first rendered into HTML content, then encrypted; transmitted to the client, then decrypted and rendered.
The decrypted content is wrapped as a dynamic Vue component, with HTML passed as the template to the dynamic component.
This involves runtime template compilation. As a result, if partial content encryption is enabled,
Vue needs to be switched to the `esm-bundler` version to support runtime compilation,
which has slightly worse performance and larger size compared to the default `runtime-only` version.

### encryptPageText

- **Type**: `string`
- **Default**: `'Only password can access this page'`
- **Description**:

  The prompt message for partial encryption. Supports HTML. Useful if you want to provide contact information for visitors to obtain the password.
