KeePassX

If you are looking for a free cross-platform password management program, try KeePassX. It is open source software, which is available under the GNU General Public License (GPL).

You can compile the software from source code or download precompiled binary versions for Linux, Mac OS X, and Windows.

Below is a screen shot from a Mac OS X entry showing fields that can be filled for a new entry in the password database.

Capturing a Screen Shot

To take a screen shot on a Mac OS X system, you can use the Grab application that comes with the operating system. To use it, take the following steps:
  1. With the finder, locate the Grab application which will be under Applications/Utilities.
  2. Open Grab
  3. Select Capture.
  4. Then select what you wish to capture. The choices are as follows:
    • Selection
    • Window
    • Screen
    • Timed Screen
  5. If you selected Window, you will see a Window Grab window appear offering you the chance to choose the window you want to capture. You can click on that window to select it and then click on the Choose Window button to capture it with Grab.
  6. Click on File and then Save to save the screen capture to a TIFF file.

Grab will save images as Tagged Image File Format (TIFF) files. You can convert such files to another graphics format, such as Joint Photographic Experts Group (JPEG) format using the Preview application that also comes with the operating system. Preview is located in the Applications folder. To convert a file from TIFF to JPEG using it, take the following steps:

  1. Open Preview, which is located in Applications, by double-clicking on it.
  2. Choose File.
  3. Chose Open and select the file to convert.
  4. Choose File.
  5. Choose Save As and select the file format you wish to use. You can choose from the following file formats:
    1. GIF
    2. JPEG
    3. JPEG-2000
    4. Microsoft BMP
    5. OpenEXR
    6. PDF
    7. Photoshop
    8. PICT
    9. PNG
    10. SGI
    11. TGA
    12. TIFF
  6. Click on Save.

There are also other third-party applications that will allow you to convert files in one graphics format to another.

As an alternative to running Grab and then Preview,you can open Preview and then from within it, select File and then select Grab, which will allow you to capture a window with Grab while inside Preview where you can select the file format you wish to use when you save the image. That can save you some steps in the process.
