Let's Encrypt is developing support for post-quantum cryptography to protect HTTPS certificates against future quantum computing threats. The certificate authority plans to issue post-quantum certificates starting in 2026.
Let's Encrypt announced plans to issue certificates using post-quantum cryptographic algorithms, addressing security risks posed by quantum computers capable of breaking current encryption methods.
The initiative involves implementing hybrid certificates that combine classical and post-quantum algorithms during a transition period. This approach ensures compatibility with existing systems while introducing quantum-resistant security.
Post-quantum cryptography relies on mathematical problems believed to resist quantum computing attacks, such as lattice-based and hash-based algorithms. Standards for these methods are being finalized by NIST, with adoption expected across the industry.
The 2026 timeline aligns with the broader industry push toward quantum-safe infrastructure. Let's Encrypt's role as a major certificate provider makes this transition significant for web security.
The move follows growing recognition that encrypted data collected today could be decrypted by quantum computers in the future, creating urgency for cryptographic modernization across critical infrastructure.
