Problem description

The value of the X-Amz-Algorithm field in the request is invalid.

Causes

You initiated a request that uses an Amazon S3-compatible V4 signature, but the value of the X-Amz-Algorithm field is invalid.

Example Problem

You initiated a request that includes the signature in the URL parameters, but the value of the X-Amz-Algorithm field is invalid.

GET /test.txt?X-Amz-Algorithm=AWS4-HMAC-SHA1&X-Amz-Credential=LTAI****************/20221220/us-east-1/s3/aws4_request&X-Amz-Date=20221220T084818Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=ab2***st HTTP/1.0

Host: oss-example.oss-cn-hangzhou.aliyuncs.com
x-oss-s3-compat: true

The X-Amz-Algorithm field specifies the signature algorithm and supports only AWS4-HMAC-SHA256. In the example, the field is set to AWS4-HMAC-SHA1, which is an invalid value.

Solutions

Replace the value of the X-Amz-Algorithm field with AWS4-HMAC-SHA256 and ensure that other request parameters are correct. The following code provides a valid example:

GET /test.txt?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=LTAI****************/20221220/us-east-1/s3/aws4_request&X-Amz-Date=20221220T084818Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=ab2s**** HTTP/1.0
Date: Tue, 20 Dec 2022 08:48:18 GMT
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
x-oss-s3-compat: true

We recommend that you use Amazon S3 SDKs to initiate the request. For more information, see Use Amazon S3 SDKs to access OSS.
