Server-Side Encryption Rules

Server-Side Encryption Rules Overview

Server-Side Encryption Rules allow you to apply Server Side Encryption automatically when you upload the files to Amazon S3.

This is a set of bucket/key rules you define in CS Browser, and CS Browser uses these rules during uploading to apply defined SSE type to the matching files.

These rules are stored locally and are CS Browser and machine specific, if you upload from another computer, the rules do not apply. You may however transfer the rules file between computers (%APPDATA%\S3Browser\bucket.rules).

There is another way to automatically apply SSE - Amazon S3 Default Bucket Encryption - an Amazon S3 feature that allows you to enable SSE on a bucket level, this is an S3 native feature and it is tool/computer independent.

The pros of CS Browser's Server-Side Encryption Rules are:

• Flexible - The rule may cover single file/folder/buket or group of files/folders/buckets.
• SSE-C support - Server-Side encryption with customer provided key (SSE-C) is supported.

The cons of CS Browser's Server-Side Encryption Rules are:

• Machine/App specific - The rules are CS Browser specific and are stored locally, if you upload from another machine or application, the rules do not apply.

To add new SSE Rule

1. Click Tools, Server-Side Encryption..

   

   The Server-Side Encryption Rules dialog will open:

3. Specify Bucket name or mask, File name or mask, and choose Encryption Type and click Add.

   Bucket name and File name are optional fields. If you will leave them empty, CS Browser will apply the rule for any file you upload to any bucket.

   You may also use wildcards to to specify the bucket or file mask, for example the file mask docs/* will apply the rule for all files you upload to the docs folder, the mask *.docx will apply the rule to all DOCX files you upload to the bucket.
