The EcdhKeyDeriveParams
dictionary of the Web Crypto API represents the object that should be passed as the algorithm
parameter into SubtleCrypto.deriveKey()
, when using the ECDH algorithm.
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.
