How can I enable SSE-S3 (AES-256) encryption in cyberduck CLI?

274 Views Asked by Vargr At 19 February 2020 at 18:26

I am attempting to use cyberduck CLI to transfer files to an Amazon S3 bucket which requires AES-256 server side encryption for uploads.

While I can find the setting for this in the cyberduck GUI I can't seem to find any method of enabling upload encryption in the cyberduck CLI.

Does cyberduck CLI even support SSE? If so how can I enable it?

Cyberduck CLI does in fact support SSE-S3 (AES-256) encryption. According to their support it can be enabled by doing the following:

• On macOS: Execute the command defaults write ch.sudo.cyberduck s3.encryption.algorithm AES256.

• On Windows: Open or create the default.properties file in %AppData%\Cyberduck and add the line s3.encryption.algorithm=AES256
