🔒 What is Perfect Forward Secrecy?
Perfect Forward Secrecy (PFS) ensures your past encrypted communications remain private, even if long-term encryption keys are compromised in the future. Learn how PFS uses ephemeral keys and algorithms like Diffie-Hellman to protect your data from retroactive decryption. Discover where PFS is used, why it matters for privacy, and its role in the future of secure communication, including post-quantum cryptography. Understand the trade-offs and benefits of this vital security measure.
