Go maintainer joins collective klaxon about encryption-breaking quantum computers — developer urges immediate switch to post-quantum methods to prevent worldwide disaster

Filippo Valsorda, the maintainer of the cryptography library in the Go language, is raising concerns about the potential threat of quantum computers breaking current encryption methods within three years. He emphasizes the need for an immediate switch to post-quantum cryptographic methods to prevent a global disaster. Valsorda highlights the urgency for the tech industry to transition swiftly to post-quantum solutions, stating that any non-post-quantum key exchange could be a security risk. The shift to post-quantum cryptography poses challenges due to increased bandwidth and latency, especially in areas like secure website connections, code signing, and blockchain technology. Valsorda warns that failing to adopt post-quantum encryption could lead to compromised security in various computing applications, including IoT devices and trusted execution environments like Intel's SGX and AMD SEV-SNP.
