@SdkPublicApi
@Immutable
@ThreadSafe
public final class SignerProperty<T>
extends Object

A strongly-typed property for input to an HttpSigner.

Signer properties are used to configure signing behavior by passing parameters to signers through AuthSchemeOptions. Common properties include signing region, service name, and signing algorithm parameters.

Common Built-in Properties

The SDK provides several built-in AWS V4 signer properties:

• AwsV4FamilyHttpSigner.SERVICE_SIGNING_NAME - The service name to use in the signature
• AwsV4FamilyHttpSigner.REGION_NAME - The AWS region for signing
• AwsV4FamilyHttpSigner.DOUBLE_URL_ENCODE - Whether to double URL-encode the path
• AwsV4FamilyHttpSigner.NORMALIZE_PATH - Whether to normalize the request path
• AwsV4FamilyHttpSigner.PAYLOAD_SIGNING_ENABLED - Whether to indicate that a payload is signed or not.

Overriding Properties via AuthSchemeProvider

To override signer properties, implement a custom AuthSchemeProvider that wraps the default provider and modifies the properties on resolved AuthSchemeOptions.

Example - Overriding service signing name:

Creating Custom Properties

When implementing a custom HttpSigner, you can define your own properties to accept additional configuration. Properties should be defined as public static constants in your signer class.

Example - Custom signer with custom property:
