Class Aws4UnsignedPayloadSigner

java.lang.Object

software.amazon.awssdk.auth.signer.internal.AbstractAwsSigner

software.amazon.awssdk.auth.signer.internal.AbstractAws4Signer<Aws4SignerParams,Aws4PresignerParams>

software.amazon.awssdk.auth.signer.internal.BaseAws4Signer

software.amazon.awssdk.auth.signer.Aws4UnsignedPayloadSigner

All Implemented Interfaces:

Presigner, Signer

public final class Aws4UnsignedPayloadSigner
extends BaseAws4Signer

Exactly the same as Aws4Signer except if the request is being sent over HTTPS, then it returns the string UNSIGNED-PAYLOAD as the content SHA-256 so services that support it can avoid needing to calculate the value when authorizing the request.

Payloads are still signed for requests over HTTP to preserve the request integrity over a non-secure transport.

calculateContentHash

protected String calculateContentHash(SdkHttpFullRequest.Builder mutableRequest,
                                      Aws4SignerParams signerParams,
                                      SdkChecksum contentFlexibleChecksum)

Description copied from class: AbstractAws4Signer

This method overloads calculateContentHash with contentFlexibleChecksum. The contentFlexibleChecksum is computed at the same time while hash is calculated for Content.

Overrides:

calculateContentHash in class AbstractAws4Signer<Aws4SignerParams,Aws4PresignerParams>
