Proton Mail现已支持后量子加密
Proton Mail 现在提供可选的后量子加密升级，适用于所有用户，包括免费用户。
此项功能利用后量子密码学 (PQC) 生成密钥，以保护未来的电子邮件安全，应对量子计算机可能破解当前公钥密码学方案的风险。
Proton Mail 长期以来使用 ECC（椭圆曲线密码学）和 RSA（RSA 加密算法）密钥进行加密，但量子计算机可能利用如 Shor 算法等技术破解这些方案。
PQC 密钥支持 OpenPGP v6 框架，并且 Proton Mail 致力于将后量子加密标准化应用于整个电子邮件生态系统，例如与 Thunderbird 等项目合作。

The quantum era is no longer a distant thought experiment. Quantum computers — advanced computing systems designed to solve complex problems that classical computers cannot — are not yet capable of breaking the encryption that protects email today. But the risk is real enough that security teams, standards bodies, and technology providers are already preparing for what comes next by adopting post-quantum encryption.
Post-quantum protection is now an optional upgrade in Proton Mail, available on all plans including free. Once enabled, Proton Mail can generate and use post-quantum-ready keys for new encrypted emails to protect your personal messages and business communications against today’s threats and a future where current public-key cryptography may no longer be enough.
