Flac Fingerprints and md5 Checksums

Here's a quick guide on how to make flac fingerprints or md5 checksums to put into your announce thread and also supply with your torrent. It also covers what you are supposed to do with them after you finish a download.

How to make a flac Fingerprint

On a PC using flac frontend:

  1. Open flac frontend
  2. Shift-select all the flac files and drop them into the open window
  3. Hit the Fingerprint button.
  4. In the box, name the flac fingerprint, usually what the name of the torrent file or show name is. Hit 'OK'
  5. Now, to put the checksums into the thread, go to the folder where you saved the ffp file
  6. Right-click -> Edit
  7. You should end up with a file that looks something like the following, simply copy and paste it into your thread.

    Sample file (only showing four lines):

    u21982-02-11t01.flac: cf86017424cad0dbedd8aefc0679ea48
    u21982-02-11t02.flac: e3e874279d6704434a710e99e2890e9a
    u21982-02-11t03.flac: 5550071e464ba8d7ae1d83128dd46148
    u21982-02-11t04.flac: 2fcb131b22e7474baacbb538bd0feef9

On a Mac using xACT:

  1. Open xACT
  2. Hit the checksum tab
  3. Hit the add button and navigate to the folder you have the flac files in
  4. Select all the flac files (select first file, shift/select last file from list) picture
  5. Click Add files
  6. Then click the checksum button in xACT window
  7. It will ask you if you want to Make Fingerpritn or Verify, hit Make Fingerprint
  8. Navigate again to the folder to be torrented and Save (I also change the name from the default fingerprint.ffp to something more appropriate, keeping the ffp extension, of course) picture
  9. Now, to put the checksums into the thread, go to the folder where you saved the ffp file.
  10. Control + click on the file and then go to Open With -> Other
  11. Navigate to your TextEdit Application (or any text editing application, I suppose) and hit Open
  12. You should end up with a file that looks like that example given above

How to make an md5 checksum

On a PC using mkwACT:

  1. Open mkwACT
  2. Hit the Options tab -> File Options
  3. Make sure you have the option "Generate md5 checksums after compressing" checked
  4. Close the Options box
  5. Hit the Options tab -> Shorten
  6. Make sure it says "Do not generate seek table" or "Save seek table in separate (*.SKI) file"
  7. Close the Options box
  8. Select your WAV files
  9. Hold down the Shif t key when you drop your WAV files onto the open window
  10. Now, to put the checksums into the thread, go to the folder where you saved the md5 file.
  11. Right -click -> Edit
  12. You should end up with a file that looks something like the following, simply copy and paste it into your thread.

    Sample file (only showing four lines):

    929198fc4b10075d3d59200b0ecda3c8 *u21982-02-11t01.shn
    5098e33b1532c708906cfaa12fdafc28 *u21982-02-11t02.shn
    c299f880f51a103ae0fb379a0ad78875 *u21982-02-11t03.shn
    0e661b6910477df6dbedb77ec8e312b9 *u21982-02-11t04.shn

On a Mac using xACT:

  1. Open xACT
  2. Hit the checksum tab
  3. Hit the add button and navigate to the folder you have the shn files in
  4. Select all the shn files (select first file, shift/select last file from list) picture
  5. Click Add files
  6. Then click the checksum button in xACT window
  7. Navigate again to the folder to be torrented and Save (I also change the name from the default md5sum.md5 to something more appropriate, keeping the md5 extension, of course)
  8. Now, to put the checksums into the thread, go to the folder where you saved the md5 file.
  9. Control + click on the file and then go to Open With -> Other
  10. Navigate to your TextEdit Application (or any text editing application, I suppose) and hit Open
  11. You should end up with a file that looks like that example given above.

How to use an ffp file (how to verify flac files)

You don't really need to 'use' an ffp file. Flac files will self-verify when you decompress them.

On a PC using flac frontend:

  1. Open flac frontend
  2. Click Add files
  3. Select all the files for the show.
  4. Click open,k then click on test.
  5. After done, scroll up and make sure all the files tested ok.

On a Mac using xACT:

  1. Open xACT
  2. Hit the checksum tab
  3. Hit the add button and navigate to the folder you have the flac files and ffp file in (they must be in the same folder)
  4. Select the ffp file picture
  5. Click Add files
  6. Then click the checksum button in xACT window picture
  7. When it is done, an new output window will pop up listing every flac file with and OK next to it (hopefully) picture. If there is a problem with a file, it will say "Error reading checksum. file may be missing or corrupt" next to the file picture.

How to use an md5 checksum (how to verify shn files)

You should always run your md5 checksum on your shn files prior to decompressing them.

On a PC using mkwACT:

  1. Double-click the md5 file -> Go to step 4 .
    If that didn't work, continue on to step 2
  2. Open mkwACT
  3. Drag the md5 checksum into the open window
  4. It will verify the files one by one as shown in the Processing Status
  5. A window will then pop up telling you they passed. If some did not pass, it will give you the option to delete the ones that did not pass.

On a Mac using xACT:

  1. Double-click the md5 file -> Go to step 7 .
    If that didn't work, continue on to step 2
  2. Open xACT
  3. Hit the checksum tab
  4. Hit the add button and navigate to the folder you have the shn files and md5 file in (they must be in the same folder)
  5. Select the md5 file picture
  6. Click Add files
  7. Then click the checksum button in xACT window
  8. When it is done, an new output window will pop up listing every shn file with and OK next to it (hopefully) picture. If there is a problem with a file, an error window will pop up and then the output window will come up and it will have an error message next to the shn file which failed and then have a warning on the bottom of the window picture.
