TLS nonce-nse

The text discusses the importance of Initialization Vectors (IVs) or nonces in encryption schemes. IVs provide non-determinism to make duplicate encrypted messages indistinguishable from each other. They are usually not secret and are distributed prepended to the ciphertext since they are necessary for decryption. The text also covers how different versions of TLS handle nonces, including RC4, CBC in TLS 1.0, TLS 1.1, TLS 1.2 GCM, and TLS 1.3. It concludes by discussing the importance of Nonce Reuse Resistance to mitigate adverse consequences when the same nonce is reused or is predictable.
