@objcMembers public class Dpop: NSObject, Codable

The Dpop class represents the context used for the Demonstrating Proof of Possession protocol used for authenticating requests that prove ownership of a private key

Properties

jwkThumbprint

public let jwkThumbprint: String

The JWK Thumbprint of the DPoP public key

Methods

isEqual(_:)

override public func isEqual(_ object: Any?) -> Bool

encode(to:)

public func encode(to encoder: Encoder) throws

Parameters

init(from:)

public required init(from decoder: Decoder) throws

Parameters

createProof(httpMethod:url:)

Create a DPoP proof token (a signed JWT) for the provided HTTP-method and URL. To sign the JWT, the cryptographic key of the Dpop context is used. This method can only be used when running Curity Identity Server versions below 7.1 which use legacy DPoP Proof configuration or when client is explicitly configured to use legacy DPoP Proof.

• Parameter httpMethod: the HTTP method of the request to authenticate

• Parameter url: the URL of the request to authenticate

• Returns: a string containing the compact serialization of a signed JWT that can be used as DPoP Proof Token for the request of url by httpMethod

• Throws: CryptoError when an error occurred with performing cryptographic operations

createProof(httpMethod:url:nonce:accessToken:)

public func createProof(httpMethod: String,
                        url: URL,
                        nonce: String? = nil,
                        accessToken: String? = nil) throws -> String

Create a DPoP proof token (a signed JWT) for the provided HTTP-method and URL. To sign the JWT, the cryptographic key of the Dpop context is used.

• Parameter httpMethod: the HTTP method of the request to authenticate

• Parameter url: the URL of the request to authenticate

• Parameter nonce: the current DPoP nonce held

• Parameter accessToken: the current held access token

• Returns: a string containing the compact serialization of a signed JWT that can be used as DPoP Proof Token for the request of url by httpMethod

• Throws: CryptoError when an error occurred with performing cryptographic operations

• Note: When running Curity Identity Server versions below 7.1 which use legacy DPoP Proof configuration or when client is explicitly configured to use legacy DPoP Proof, omit parameters nonce and accessToken.

Parameters

getHeaderValue(httpMethod:url:)

Calculate the DPoP request header value that can be used to authenticate a request of url by httpMethod. This method can only be used if running Curity Identity Server versions below 7.1 which use legacy DPoP Proof configuration or when client is explicitly configured to use legacy DPoP Proof.

• Parameter httpMethod: the HTTP method of the request to authenticate

• Parameter url: the URL of the request to authenticate

• Returns a String with the header value

• Throws: CryptoError exception when the DPoP proof token could not be generated due to a cryptograhic error

getHeaderValue(httpMethod:url:nonce:accessToken:)

public func getHeaderValue(httpMethod: String,
                           url: URL,
                           nonce: String? = nil,
                           accessToken: String? = nil) throws -> String

Calculate the DPoP request header value that can be used to authenticate a request of url by httpMethod.

• Parameter httpMethod: the HTTP method of the request to authenticate

• Parameter url: the URL of the request to authenticate

• Parameter nonce: the current DPoP nonce held

• Parameter accessToken: the current held access token

• Returns a String with the header value

• Throws: CryptoError exception when the DPoP proof token could not be generated due to a cryptograhic error

• Note: When running Curity Identity Server versions below 7.1 which use legacy DPoP Proof configuration or when client is explicitly configured to use legacy DPoP Proof, omit parameters nonce and accessToken.
