Authentication

AK/SK authentication is used for calling APIs. Specifically, requests are encrypted using the access key (AK) and secret key (SK) to provide higher security.

AK/SK Authentication

In AK/SK authentication, AK/SK is used to sign requests and the signature is then added to the requests for authentication.

AK: access key ID, which is a unique identifier used in conjunction with a secret access key to sign requests cryptographically.
SK: secret access key used in conjunction with an AK to sign requests cryptographically. It identifies a request sender and prevents the request from being modified.

In AK/SK authentication, you can use an AK/SK to sign requests based on the signature algorithm or use the signing SDK to sign requests. For details about how to sign requests and use the signing SDK, see API Request Signing Guide.

The signing SDK is only used for signing requests and is different from the SDKs provided by services.
