Field Detail

SIGNING_CLOCK

static final SignerProperty<Clock> SIGNING_CLOCK

A Clock to be used to derive the signing time. This property defaults to the system clock.

Note, signing time may not be relevant to some signers.

Method Detail

doNotSign

default <T extends Identity> HttpSigner<T> doNotSign()

Retrieve a signer that returns the input message, without signing.

sign

SignedRequest sign(SignRequest<? extends IdentityT> request)

Method that takes in inputs to sign a request with sync payload and returns a signed version of the request.

Parameters:

request - The inputs to sign a request.

Returns:

A signed version of the request.

sign

default SignedRequest sign(Consumer<SignRequest.Builder<IdentityT>> consumer)

Method that takes in inputs to sign a request with sync payload and returns a signed version of the request.

Similar to sign(SignRequest), but takes a lambda to configure a new SignRequest.Builder. This removes the need to call SignRequest#builder(IdentityT)} and SdkBuilder.build().

Parameters:

consumer - A Consumer to which an empty SignRequest.Builder will be given.

Returns:

A signed version of the request.

signAsync

CompletableFuture<AsyncSignedRequest> signAsync(AsyncSignRequest<? extends IdentityT> request)

Method that takes in inputs to sign a request with async payload and returns a future containing the signed version of the request.

Parameters:

request - The inputs to sign a request.

Returns:

A future containing the signed version of the request.

signAsync

default CompletableFuture<AsyncSignedRequest> signAsync(Consumer<AsyncSignRequest.Builder<IdentityT>> consumer)

Method that takes in inputs to sign a request with async payload and returns a future containing the signed version of the request.

Similar to signAsync(AsyncSignRequest), but takes a lambda to configure a new AsyncSignRequest.Builder. This removes the need to call AsyncSignRequest#builder(IdentityT)} and SdkBuilder.build().

Parameters:

consumer - A Consumer to which an empty BaseSignRequest.Builder will be given.

Returns:

A future containing the signed version of the request.
