Encryption, or the encoding of messages in such a way that only intended recipients can understand them, is one of the main tools to guarantee the security of our information. It is recognised as necessary for the digital economy and for the protection of fundamental rights, such as privacy and free speech.
While law enforcement requires the means to fight crime on the internet, any new measure would have to first pass the test for necessity and proportionality, based on substantiated evidence. While encryption makes bulk data collection and mass surveillance difficult, it is not a limiting factor in more targeted and specific measures. Restrictions on encryption pose significant risks to the economy and society in general.
