Encryption Strength Warning

Although JetS3t includes support for data encryption, Sun's Java distribution does not always include support for industrial-strength encryption algorithms. JetS3t comes configured to use a relatively weak encryption algorithm (PBEWithMD5AndDES) that is available by default on all platforms and Java versions from 1.4. If you intend to encrypt your data in S3, we recommend that you configure Java and JetS3t to use a much stronger algorithm than this.

To enable full-strength encryption algorithms on your system, you may need to configure Java by downloading and installing the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files available for Java versions 1.4.2 or later.

Once Java is configured to enable full-strength encryption algorithms, you will have a wide range of algorithms to choose from as JetS3t now includes the excellent Bouncy Castle security provider suite. You can configure your preferred algorithm in the jets3t.properties configuration file or via the Preferences dialog in Cockpit. We recommend you use a strong algorithm such as PBEWithSHAAnd256BitAES-CBC-BC or PBEWithSHAAndTwofish-CBC.
