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

AK/SK-based Authentication

NOTE:

AK/SK-based authentication supports API requests with a body not larger than 12 MB. For API requests with a larger body, token-based authentication is recommended.

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

NOTICE:

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