Resumo

The Mutt email client uses Ed25519 for Autocrypt key generation, which is vulnerable to quantum attacks via Shor's algorithm. While Ed25519 is currently secure against classical attacks, systems expecting long-term confidentiality (5-10+ years) face significant risk as quantum computers advance. Migration to NIST-approved post-quantum algorithms is necessary for future-proof cryptographic protection.
