Encryplet is a US$5 shareware AppleScript® droplet which makes it easy to encrypt and decrypt files by drag-and-dropping them onto a Desktop Encryptor icon (similar to the Desktop Printer icons in QuickDraw GX and System 7.5.1 and later).
Encryplet relies on your AppleScript-aware version of Philip Zimmermann's PGP software –MacPGP®– to perform encryption and decryption. For information on how to obtain MacPGP in the USA or Canada, first refer to <ftp://ftp.netcom.com/pub/dd/ddt/crypto/crypto_info/where> using your FTP client or a World Wide Web browser. For non-USA citizens, information on how to obtain MacPGP is available at Ståle Schumacher's International PGP Home Page <http://www.ifi.uio.no/~staalesc/PGP/>.
If you require human assistance on using the PGP software (not Encryplet), send e-mail to <mailto:pgp-help-humans@hks.net>. For Encryplet problems, questions, etc… send e-mail to <mailto:T-and-G@kagi.com>.
Note: Because PGP also compresses data when encrypting it, Encryplet can also be useful as an easy-to-use, effective data compression utility while it secures your private information - I was able to reduce some text files to 27% of their original size.
Software required
To use Encryplet you need to have:
1. An AppleEvent aware version of MacPGP,
2. The Scriptable Finder (MacOS 7.1.4 or later),
3. The AppleScript Extension in your Extensions folder, with the standard Apple osaxen, and of course
4. Encryplet.
Installation
1. Put Encryplet on your desktop so it can be accessible for drag-and-drop operation. Better still, put it somewhere else and create an alias to it (select it and choose Make Alias… under the File menu in the Finder or press Command-M key combo). Move the alias to an accessible place on your desktop.
2. Double-click Encryplet and set its global preferences (see • Setting global preferences in next section).
Operations
Encryplet can be launched in two ways and will behave differently accordingly.
1. Double-clicking Encryplet icon: Allows setting global preferences, and
2. Drag-and-dropping file(s) and folder(s) onto Encryplet: PGP Encrypts or PGP Decrypts dropped file(s) and folder(s) contents. The output file(s) is/are always created in the same folder as the source.
• Setting global preferences
When you double click Encryplet, it sets its global preferences. Here are the details:
•• Setting your User-ID
Encryplet tries to locate your PGP Preferences file which is supposed to be located in the Preferences folder inside the active System Folder. If successful, Encryplet will read your User-ID information from this file and use it to PGP Encrypt the files you will drag-and-drop onto it after MacBinarising it/them.
Note: If Encryplet is unable to find a valid User-ID in the PGP Preferences file, or if this file does not exist, it prompts you to enter a value that will be used as a User-ID. Bear in mind, that if MacPGP is unable to act upon this value, an error (usually #21: RSA Key Encryption Error) will occur.
•• Wipe Source File
Next, Encryplet will prompt you whether you want to wipe the source file(s) after you process it/them, be it after encryption or decryption. If you elect not to wipe the source file, the output file will overwrite the source if you have checked the Overwrite Files option under the Options menu in MacPGP.
Note: Overwriting a file does not wipe the contents of the old copy, so… do not consider Overwriting Files as a secure way of getting rid of clear (pre-encrypted) data. The Overwrite Files will not protect you from very sophisticated attacks.
•• Quit MacPGP When Done
Finally, Encryplet will prompt you whether you want to quit the MacPGP application after it finishes using it for encryption and decryption of dropped objects (files and folders).
Note: If you answer yes to this question then remember that you'll have to enter your secret pass-phrase everytime Encryplet is launched to do its work.
• Processing files
Encryplet will PGP Encrypt every file drag-and-dropped onto its icon, with you the user/owner as the recipient, after MacBinarizing it, unless the file is already a MacPGP encrypted file; ie. it bears MacPGP's signature. In the latter case, Encryplet opens it through MacPGP, causing it to be decrypted.
Note: Encryplet will always MacBinarise the file(s) you drop onto it. This will save all Macintosh related information such as the file's type and creator. In doing so, Encryplet when decrypting back the file, will restore it to its original double-clickable state.
Scriptability
Encryplet's dictionary consists of the following:
Required Suite:
open: Open the specified object(s)
open alias -- list of objects to open
quit: Quit the Finder (direct parameter ignored)
quit
run: Sent to an application when it is double-clicked
Process1Object file specification -- Target Finder object.
Result: anything
Process1Folder: Processes one Finder folder.
Process1Folder file specification -- path or alias to specified folder
Result: anything
Process1File: Processes one Finder file.
Process1File file specification -- path or alias to specified file
Result: anything
Here is an example of processing a file through Encryplet
tell application "Encryplet"
launch
Process1File (alias "Disk:Desktop Folder:Web Audit Report For Accoun.pgp")
end tell
Acknowledments
Encryplet was beta-tested by, and refined based on responses from, the following people: Bjorn E. Andersson, Marshall Clow, Dave Del Torto, Michel Eytan, Robert Guerra, Dennis Steele and David Stoler. My gratitude goes to them and especially to Dave Del Torto who found the time to also review and improve this documentation. Any remaining weaknesses in the grammar or ambiguities in interpreting this text is mine and not his.
Shareware Fee

The author and copyright holders retain complete and exclusive rights to the program, but specifically allow re-distribution via the following channels:
1. NON-COMMERCIAL bulletin board services,
2. INTERNET archives and file servers,
3. Disk libraries of NON-PROFIT organizations.
provided that all the contents of the folder containing the software and documentation are kept together.
Encryplet is Shareware. You may use the software for a trial period of 4 weeks. If you decide to continue using it, you must pay the shareware fee.
Encryplet has the following pricing:
• The individual user license fee is US$5, or AUD5 for Australian residents only.
• A Site License costs US$100 and covers all locations for your organisation within a 160 kilometer radius of your site (100 miles). One big advantage of a Site License is that you do not need to keep track of how many people at your site are using the Encryplet software.
• A World-Wide License costs US$500 and it covers all locations for your organisation on the planet Earth.
Paying for Encryplet
Paying for Encryplet is fairly simple. Open the Register program that accompanies Encryplet. Enter your name, your email address, and the number of single user licenses you desire for each program you wish to purchase (or Site or Word-Wide licenses). Save or Copy or Print the data from the Register program and send the data and payment to Kagi Shareware. Kagi Shareware handles my payment processing.
If paying with Credit Card or First Virtual, you can email or fax the data to Kagi Shareware. Their email address is <mailto:shareware@kagi.com> and their fax number is +1 510 652-6589. You can either Copy the data from Register and paste it into the body of an email message, or you can Save the data to a file which you attach to an email message. There is no need to compress the data file, it's already pretty small. If you have a fax modem, just Print the data to Kagi's fax number.
Payments sent via email are processed within 3 to 4 days. You will receive an email acknowledgement when it is processed. Payments sent via fax take up to 10 days and if you provide a correct Internet email address you will receive an email acknowledgement.
If you are paying with Cash (outside Australia) or US$ Check you should print the data using the Register application and send it to the address shown on the form, which is:
Kagi Shareware
1442-A Walnut Street #392-GT
Berkeley, California 94709-1405
USA
If you're a resident of Australia and are paying in AUD our address is:
Type & Graphics Pty Limited
POB 5607
Chatswood West NSW 2057
Australia
You can pay with a wide variety of cash from different countries but at present if you pay via cheque, and unless you're a resident of Australia, it must be a cheque drawn in US$. Kagi Shareware cannot accept cheques in other currencies, the conversion rate for non-US$ cheques is around US$15 per cheque and that is just not practical.
If you have a purchasing department, you can enter all the data into the Register program and then select Invoice as your payment method. Print three copies of the form and send it to your accounts payable people. You might want to highlight the line that mentions that they must include a copy of the form with their payment.
Kagi Shareware can not invoice your company, you need to act on our behalf and generate the invoice and handle all the paperwork on your end.
Please do not fax or email payment forms that indicate Cash, Check or Invoice as the payment method. As far as we know, there is still no technology to transfer physical objects via fax or email and without the payment, the form cannot be processed.
Payments send via postal mail take time to reach Kagi Shareware and then up to 10 days for processing. Again, if you include a correct email address, you will hear from Kagi Shareware when the form is processed.
