ECDH enables two people who each have a key pair consisting of a public and a private key to derive a shared secret. They exchange public keys and use the combination of their private key and the other entity's public key to derive a secret key that they — and noone else — share.
The parameters for ECDH
deriveKey() therefore include the other entity's public key, which is combined with this entity's private key to derive the shared secret.
DOMString. This should be set to
CryptoKeyobject representing the public key of the other entity.

The definition of 'SubtleCrypto.EcdhKeyDeriveParams' in that specification.
Browsers that support the "ECDH" algorithm for the
SubtleCrypto.deriveKey() method will support this type.
