This page contains links to official releases of JetS3t. To obtain the latest code, or to contribute to the project, visit the development site at http://bitbucket.org/jmurty/jets3t/.
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, 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.

jets3t-0.8.1.zip (11.6 MB, MD5: 187b3233453499121a4871b9df39bd52) |
New Amazon S3 features:
-
Added support for the Multipart Uploads feature, including the
utility class MultipartUtils to make it easier to use.
-
Added support for the Website Configuration feature, which allows
static S3 bucket to behave more like a dynamic web site with
custom index and error documents.
-
Added support for configuring buckets to send Simple Notification
Service (SNS) messages.
-
Added threaded service subclass of ThreadedStorageService for
features specific to Amazon's S3, namely multipart upload.
New Amazon CloudFront features:
-
Added support for custom (non-S3) distribution origins (API 2010-11-01).
This improvement involved changes to the CloudFrontService API which
are not backwards-compatible, so code that relies on the prior version
will need to be updated.
Bug fixes:
-
Fixed incorrect file path for XMLBuilder library in shell scripts.
-
Fixed nasty Cockpit bug that prevented directories from being included when
uploading files.
-
Fixed issue in FileComparer utility that prevented locally-deleted
files within directories from being noticed and removed from the
remote service. Also affected JetS3t's Synchronize and Cockpit apps.
See issue 69.
New toolkit functionality / improvements:
-
StorageObject and its subclasses (e.g. S3Object) now include a convenience
constructor that accepts byte array data.
-
Greatly reduced memory usage in FileComparer file comparison
utilities when working with large numbers of files.
-
FileComparer utility now skips/ignores 'special' files on the local
file system, to avoid problems synchronizing system directories
that contain files that are not really data and cannot be
synchronized to a storage service.
Synchronize application updates:
-
Improved batching algorithm to reduce memory usage when working with
large numbers of files.
-
Added support for the Amazon S3 service's Multipart Upload feature,
which allows large files to be uploaded in smaller parts for improved
transfer performance or to upload files larger than 5 GB.
-
Added new property `upload.max-part-size` to synchronize.properties
file, to allow the maximum upload part size to be configured when
using the Amazon S3 service. The maximum part size defaults to 5 GB.
-
Improved file comparison logic so object metadata is only retrieved
from a service when it is required.
-
Removed support for `--skipmetadata` option. This option is no longer
necessary since metadata retrieval is more intelligent, and is not
desirable because metadata retrieval is no longer optional when
comparing objects uploaded using the Multipart Upload mechanism.
