Jacksum 1.7.0, July 30, 2006
- added a customizable CRC algorithm, now you can calculate any CRC which
  can be described by the Rocksoft Model CRC Algorithm (8 to 64 bit width),
  see also sf# 1518023 Setting of an initial value for a CRC
- support for combinable checksums, see also sf# 1210489
  (multiple hashes at the same time), thanks to synonymous2 for this feature request
- support for using all algorithms at once (-a all)
- two new algorithms are supported: crc32_bzip2, HAS-160
- support for Tiger Tree hashes (aka Merkle Hashes). Thanks to Carsten Krüger,
  Germany for the feature request and pointers to some resources
- support for new encodings (bin, dec, oct)
- support for the combination of both options -c and -w,
  Thanks to Dipl.-Inf. (FH) Ralf Kahrl, Germany for the implementation of this feature
- a small performance improvement for the whirlpool algorithms
- replaced the crc24 with a faster one by using the customizable CRC algorithm
  (the old one had also a minor bug in the parameterless constructor)
- bug fixed: -V summary does not always return reasonable values
- bug fixed: update(byte[], int, int) fails if offset is > 0 (sf # 1525183)
  This can cause problems if Jacksum is incorporated in different projects
- The bouncycastle and gnu classes have been moved to jonelo.jacksum.adapt so that
  they won't clash with different downloaded versions of the classes. Actually this
  is to avoid potential problems if a project uses both bouncycastle and Jacksum for example.
  Thanks to Alberto Rodriguez, Spain for the feature request
- documentation updated (BeOS' data integrity programs, Tru64 and year of the invention for
  many algorithms)
- tested with gij 4.0.2, JRE 1.3.1_18, 1.4.2_12, 5.0_07, 6.0-rc-b93

  Thanks to Christoph R., Germany and niku.u for the bug reports (sf# 1354426)
- bug fixed: stdout and stderr overwrite each other when stdout and stderr are equal
- bug fixed: -c and -V summary give meaningless summary
- exit status depends on the result of -c now
  Thanks to Martin Z., Germany for the feature request
- improved documentation ("exit status" and "see also" have been added)

Jacksum 1.6.0, Sep 3, 2005
- 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
- change: "whirlpool" refers to Whirlpool-2 now, rather than to Whirlpool-1  
- support for an alternate Adler 32 implementation
- improved option -c: Jacksum can check the integrity even if a file list has
  not been created by Jacksum (or a file list without meta information)
  Thanks to Sebastian J., Germany for this feature request
- new option -w for setting the working directory
- new algorithm-code called "none" for ignoring the real content of
  the files for being able to check just against the filesize
- new algorithm-code called "read" for being able to read the file's content,
  but without doing any calculation
- new option -E for an encoding of the checksum (hex, hexup, Base 16, Base 32,
  Base 64 and BubbleBabble are supported)
- new option -g (group some bytes) for better readability of a hex checksum
- new option -G (group separator) for better readability of a hex checksum
- new option -o for redirecting the output to a file rather than the standard output,
  in this case the file is also excluded from the calculation process
- new option -O for overwriting an existing file
- new option -I for ignoring lines when checking the integrity by -c
- new option -V for a verbose output (number of processed files and dirs, processed bytes,
  number of read errors and elapsed time)
- improved option -e: works also for multiple files and directories 
  for being able to find duplicates
- improved option -e: when using -e, the option -x is not necessary anymore,
  if the return value by default is hex anyway 
- improved option -m: unnecessary defaults are not be written to the header anymore
- improved option -h: can show only fractions of the help file rather than
  the complete help file
- improved option -t: #SEPARATOR and #QUOTE are also replaced
  Thanks to Claudio C., Italy for the feature request
- improved option -F: #FILENAME{NAME} and #FILENAME{PATH} can be used
  Thanks to Claudio C., Italy for the feature request
- bug fixed: if calling the getHexValue() method more than once, the hash based
  algorithms return a different value; this can cause problems if Jacksum 
  is used in other projects, Thanks to Bob C. for the bug report
- bug fixed: problem on Unix/Linux while checking a file list if the filename's
  last character is a colon (e. g. "Terminal 1:")
- improved documentation, added also collision files
- improved the public API (support a method to return byte[])
  Thanks to Alex G., Germany for this feature request
- improved the public API for other projects (methods getAvailableAlgorithms(),
  and equals() have been added)
- Added javadoc, Thanks to Corey Osman for this feature request
- refactored and code improvements

  Thanks to Lee A. Davis for the bugreport
- bug fixed: Jacksum hangs if it reaches a fifo under Unix/Linux
- bug fixed: files which are used by another process can't be processed properly
- new option -d for ignoring symbolic links to directories under Unix/Linux to avoid
  enless loops in particular cases
- improved option -q to support not only hex, but also text and decimal formats
- new option -F for being able to customize the output format
  see also sourceforge feature request #968469 (show file length on MD5)

- lists created with -m are platform independent now, you can verify files against
  a list on Linux/Unix if the list has been created on Windows for example
- new option -S to calculate just one fingerprint (summary)
  Thanks to Berthold Kohlmann, Germany for this feature request

  and round parameters (3 to 5)
- algorithms sha-256, sha-384 and sha-512 are also supported with JRE 1.3 now

  Thanks to Daniel Ellermann, Germany for both feature request and
  reference implementation

  generator poly X^16 + X^15 + X^2 + 1.
