"23. In spite of its benefits, Governments sometimes restrict the use of encryption, for example for the protection of national security and combating crime, in particular to detect child sexual abuse material. Restrictions include bans on encrypted communications and criminalization for offering or using encryption tools or mandatory registration and licensing of encryption tools. Similarly, in some instances, encryption providers have been required to ensure that law enforcement or other government agencies have access to all communications upon request, which can effectively amount to a blanket restriction of encryption that could require, or at least encourage, the creation of some sort of back door (a built-in path to bypass encryption, allowing for covert access to data in plain text). Another form of interference with encryption is the requirement that key escrow systems be created and maintained, and all private keys needed to decrypt data be handed over to the Government or a designated third party. The imposition of traceability requirements, according to which providers need to be able to trace any message back to its supposed originator, could also require the weakening of encryption standards. Recently, various States have started imposing or considering general monitoring obligations for providers of digital communications, including those offering encrypted communications services. Such duties could effectively force those providers to abandon strong end-to-end encryption or to identify highly problematic workarounds (see paras. 27-28 below).
