Encoding Settings

This topic contains details for encoding settings related to decryption of videos.

Overview

Zencoder supports processing encrypted media files using the “encryption at rest” paradigm; we retrieve the encrypted files from your server, and only decrypt them while processing. The decrypted version of the file is removed immediately after processing, keeping your data secure.

We support both AES-128 and AES-256 encrypted files in CBC and CTR modes. Decryption parameters must be included with your job request. Decryption is enabled when either a decryption_key or decryption_key_url is specified.
