Britain wants to ban methods of internet-encryption that are too hard to crack.

Internet and social media companies will be banned from putting customer communications beyond their own reach under new laws to be unveiled on Wednesday.
Companies such as Apple, Google and others will no longer be able to offer encryption so advanced that even they cannot decipher it when asked to, the Daily Telegraph can disclose.
Measures in the Investigatory Powers Bill will place in law a requirement on tech firms and service providers to be able to provide unencrypted communications to the police or spy agencies if requested through a warrant.

In other words: They want to ensure by law that your encryption has a back-door that somebody else can use. This "somebody else" could be the GCHQ, it could be hackers...

In the words of Edward Snowden: They wouldn't just ensure a back-door for surveillance-agencies. They would effectively "ban encryption that works."
