▸ DPoP(client, keyPair, options?): DPoPHandle

Returns a wrapper / handle around a CryptoKeyPair that is used for negotiating and proving proof-of-possession to sender-constrain OAuth 2.0 tokens via DPoP at the Authorization Server and Resource Server.

This wrapper / handle also keeps track of server-issued nonces, allowing requests to be retried with a fresh nonce when the server indicates the need to use one. isDPoPNonceError can be used to determine if a rejected error indicates the need to retry the request due to an expired/missing nonce.

Parameters

Parameter	Type	Description
client	Pick<Client, typeof clockSkew>	-
keyPair	CryptoKeyPair	Public/private key pair to sign the DPoP Proof JWT with
options?	ModifyAssertionOptions	-

Returns

DPoPHandle

Example

let client!: oauth.Client
let keyPair!: oauth.CryptoKeyPair

let DPoP = oauth.DPoP(client, keyPair)
