How Encryption Works
Encryption relies on symmetric or asymmetric methods, where data is encoded with a key and decoded only by the matching one. AES-256, a gold standard, converts plain text into ciphertext that's gibberish without the key, protecting it during transmission. Perfect Forward Secrecy adds layers by generating unique keys per session, preventing past breaches from exposing future data.
