You can encrypt a specific input stream using static key AES scrambling encryption (AES 128, AES 192, AES 256). If the stream has been encrypted at the source, it can be encrypted by ZEC only after its decryption (See [ZEC Decrypting an Input Stream](docId\:Za1bu5GIx3JA4mcTJY7wb) ). The stream encryption prevents any further processing, such as analysis, transcoding, etc.

**To encrypt an input stream in ZEC:**

::::WorkflowBlock
:::WorkflowBlockItem
In **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, 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.
