S3 Put Bucket Encryption

PUThttps://s3.<your-region>.backblazeb2.com/<your-bucket-name>/?encryption

Sets the bucket's explicit default encryption configuration. Backblaze B2 supports AES256, which maps to SSE-B2. Server-side encryption cannot be disabled, and SSE-KMS is not supported. If no explicit configuration is stored, the effective default remains AES256. This operation requires permission to write bucket encryption configuration.

A successful request returns 200 OK with no response body.
