WebThis document is a W3C Recommendation of the Web Cryptography API specification. This document is produced by the Web Cryptography WG of the W3C. An implementation report is also available (as well as reports sent to the mailing list). Ongoing discussion will be on the [email protected] mailing list . Elliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. This shared secret may be directly used as a key, or to derive another key. The key, or the derived key, can then be used to encrypt subsequent communications using a symmetric-key cipher. It is a variant of the Diffie–Hellman protocol using elliptic-curve cryptography.
