A leaked European Council document reveals that Spain wants to ban end-to-end encryption, with 15 out of 20 EU countries expressing support for scanning encrypted messages for illegal content. The proposed law aims to stop the spread of child sexual abuse material, but experts argue that it would undermine online privacy and security. Some countries, like Germany, oppose the proposal, citing concerns about data protection and the potential for abuse. The document highlights the ongoing debate between law enforcement and privacy advocates over the use of encryption.
