WebChaCha20-Poly1305 is an authenticated encryption with additional data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. Its usage in IETF protocols is standardized in RFC 8439. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM. WebOne common use is with web browsers that use ephemeral Diffie-Hellman keys, EDH or DHE keys we call that. And we can combine this with elliptic curve cryptography to have elliptic curve Diffie-Hellman key exchange. ...

WebMay 9, 2013 · For ephemeral Diffie-Hellman (DHE) cipher suites, the RSA private key is only used for signing the DH parameters (and not for encryption). These parameters are used in a DH key exchange, resulting in a shared secret (effectively the pre-master secret which is of course not visible on the wire). Web"DHE_RSA" cipher suites provide forward secrecy because the actual key exchange secret (the DH private key) is transient, thus not saved by the server -- if the server does not save that key on its disk, then it should be …
