* Gnome Nautilus on Linux/Unix

customizable CRC algorithms due to the Rocksoft Model CRC Algorithm are supported now. Algorithms can be combined together and multiple hashes can be calculated at the same time. The korean standard HAS-160, the CRC of Bzip2, and are Tiger Tree Hashes are supported as well. New encodings (dec, oct, bin) have been introduced. Performance and code improvements, bug fixes and the documentation has been updated.

The Jacksum Windows Explorer Integration program installs Jacksum's primary feature (compute checksums, CRCs and hashes) at the Windows Explorer.

The Jacksum File Browser Integration script installs Jacksum's primary feature (compute checksums, CRCs and hashes) at your favorite file browser on Linux or Unix operating systems: KDE Konqueror and/or Gnome Nautilus.

The changes in this release are as follows: A critical regression bug has been fixed (-r does not work anymore on Linux/Unix). Two minor bugs have been fixed: "stdout and stderr overwrite each other when stdout and stderr are equal", and "-c and -V summary give meaningless summary". The exit status depends on the result of the verification process, and the documentation has been updated.

The major changes in this release are as follows:

Twelve new algorithms are supported: CRC-8, CRC-24, GOST R 34.11-94, SHA-0, SHA-224, Tiger-128, Tiger-160, Tiger2, Whirlpool-0, Whirlpool-2, RIPEMD-256, RIPEMD-320. Jacksum is also able to check the integrity, even a file list has not been created
by Jacksum. Fingerprints can be not only encoded hexadecimal but also Base16, Base32, Base64 and BubbleBabble. Hex values can be grouped by bytes for better readability. Option -e works also for multiple files and directories for being able to find duplicates. The working directory can be set by commandline. Options are available for redirecting the output to a file rather than the standard output/error.
A verbosed output is possible now to get a summary which also helps to compare the performance of algorithms easier. Both the API and the documentation has been updated. Collision example files are available and javadoc can be created. The help on the commandline is much more user friendly.
All bugs have been fixed which were detected during the last ten months. Jacksum has also been tested sucessfully with latest free JVMs like Kaffe and gij.... read more

The changes in this release are as follows:
The regression bug has been fixed (when option -l is used, removed files will not be printed out to the standard output anymore). The Sourceforge feature request #1028824 has been implemented (add homepage URI if -m is used) and the documentation has been improved.

It's required to use at least JRE 1.3.1, but JRE 1.4.2 or JRE 5.0 are recommended.

The changes in this release are as follows:
Four new algorithms are supported (eDonkey/eMule, FCS-16, ELF-32, and CRC-64). The input on the command line supports not only hex, but also text and decimal formats now. You can verify files against a list on Linux/Unix if the list has been created on Windows and vice versa. The format for the output can be customized (e.g. creating SFV files, ed2k lists, or showing file length on MD5). It is also possilbe to calculate just one fingerprint for multiple files or a whole drive. Sourceforge bug #948070 (-c wouldn't work if -t had been set) has been fixed and Jacksum is now aware of FIFOs and symbolic directory links on on Unix/Linux.... read more

The changes in this release are as follows:
Three new algorithms are now supported: Tiger, Haval, and the MPEG spec of CRC-32. Haval can have both length (128, 160, 192, 224, or 256 bits) and round parameters (3 to 5). The algorithms SHA-256, SHA-384, and SHA-512 are also supported with JRE 1.3.1 now. Three new options have been introduced, -p for including path information, -l to show a list of modified resp. deleted files only, and -e for comparison against an expected checksum. Furthermore, the documentation has been updated with info about MacOS X's checksum tools.... read more

A new version of Jacksum has been released!

Jacksum is a free and platform independent utility for computing and verifying checksums, CRCs and message digests as well as timestamps of files. Jacksum is entirely written in Java. It supports most common checksum algorithms (Adler32, BSD sum, POSIX cksum, CRC-16, CRC-32, MD2, MD4, MD5, RIPEMD-128, RIPEMD-160, SHA-1, SHA-256, SHA-384, SHA-512, Unix System V sum, sum8, sum16, sum24, sum32, Whirlpool and xor8).... read more
