1. A method comprising:

  • receiving, by a system and from a first encryption manager separate from the system, a first set of encryption management data converted from a proprietary format of a first conditional access system to a standard format different from the proprietary format of the first conditional access system, wherein the first set of encryption management data comprises an encryption algorithm;

    converting the first set of encryption management data from the standard format to a format useable by a first encryption module of the system, wherein the format useable by the first encryption module is different from the standard format;

    in response to the receiving and subsequent to the converting, configuring the first encryption module of the system using the first set of encryption management data resulting in a configured first encryption module;

    in response to configuring the first encryption module, receiving a first set of encryption control data comprising one or more control words;

    in response to receiving the first set of encryption control data, encrypting, by the configured first encryption module, a content item using the one or more control words and in accordance with the first set of encryption management data; and

    transmitting, by the system and to a device, the encrypted content item.
