# EcdhKeyDeriveParams

The `EcdhKeyDeriveParams` represents the object that should be passed as the algorithm parameter into [`deriveBits`](/docs/k6/latest/javascript-api/crypto/subtlecrypto/derivebits/), when using the ECDH algorithm.

ECDH is a secure communication method. Parties exchange public keys and use them with their private keys to generate a unique shared secret key.
