You can encrypt a specific input stream using static key AES scrambling encryption (AES 128, AES 192, AES 256). The stream encryption prevents any further processing, such as analysis, transcoding, etc. For more information, see the [Transcoder](docId\:N_HeHZq5awqzbZmJsgxEH) section.

The encryption works in the following way:

- **If the stream has been encrypted at the source** - The stream will remain encrypted regardless of the output type. ZEC can only encrypt the stream after it has been decrypted. 
- **If the stream is being encrypted by the ZEC** - it will be encrypted only if the output is a Zixi Pull or Zixi Push output. All other outputs will send out an unencrypted stream.

### To encrypt an input stream in ZEC:

::::WorkflowBlock
:::WorkflowBlockItem
In the **Inputs** screen, click **+New Input**.
:::

:::WorkflowBlockItem
Select the relevant input type.
:::

:::WorkflowBlockItem
Fill in the stream parameters.
:::

:::WorkflowBlockItem
At the bottom, select the **Enable Encryption** checkbox.
:::

:::WorkflowBlockItem
In the **Encryption Type** field, select AES 128, AES 192, or AES 256 for fixed encryption.
:::

:::WorkflowBlockItem
In the **Encryption Key** field, enter your own key or click **Generate** to generate a key by the system. The exact key should be used to decrypt the stream on the other end.
