Problem description
MD5 value of the key provided by SSE-C encryption is empty.
Root cause
When using SSE-C encryption, the Base64-encoded 128-bit MD5 digest of the encryption key is not provided.
Example
When uploading an object, the x-tos-server-side-encryption-customer-key-MD5 header is missing.
PUT /object HTTP/1.1
Host: <Bucket name>.<TOS endpoint>
Date: Fri, 30 Jul 2021 13:59:18 GMT
Authorization: authorization xxx
x-tos-server-side-encryption-customer-algorithm: AES256
x-tos-copy-source-server-side-encryption-customer-key: YWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWE=
......
Solution
When using SSE-C encryption, use the x-tos-server-side-encryption-customer-key-MD5 header to provide TOS with the Base64-encoded 128-bit MD5 digest of the encryption key to ensure the key is transmitted correctly. For more information, see Server-Side Encryption with Customer-Provided Keys (SSE-C).
