In this mode the program uses a 256-bit RC-4WA algorithm. This mode is faster (speed is up to 90 kB/s), and uses very small memory. Use this mode if you are low in memory.
Safer SK-128:
This mode uses a 128-bit Safer as algorithm. This is a bit slower (speed is up to 52 kB/s), but uses a lot more memory. This extra memory need is only temporary, it is regained after the file is done.
For a more technical description about these algorithms see "Algorithms".

It is possible to run two copies of Encrypt-it at the same time, however, you can't start these two copies from the Extras bar.
Do this: run the first copy from the Extras bar. Go to the system screen, and locate the encrypted file that you want to process, and if you press Enter, a second copy of Encrypt-it! is launched with this file.
This way you can Quick Update several files at the same time, while each copies of Encrypt-it! are waiting in the background.
NOTE: Before this mode works, you have to make sure that "Enter" opens a program twice. Go to the system screen, press CTRL-K for the "Preferences", and on the bottom select "Enter" to "Open multiple files". If you don't want to change this, it is fine, just remember to press "Fn+Enter" if you want to run Encrypt-it! twice.
When a file is deleted from your disk by the Series 5, its content may remain there for a while as unknown byte pieces. This way, a sophisticated hacker can find portions of the deleted files using a Disk Editor. This is why wiping is so important.
Encrypt-it! doesn't simply delete the files, instead, it wipes their contents first, then erases them from the disk. Dont't worry, this entire process only takes less than a second, but this way your unencrypted data is physically removed from the disk, making the process even more secure.

RC-4WA:
This is a C++ implementation of the well-known RC-4 algorithm. WA means work-alike, I simply call it that way because the RC-4 name is copyrighted. The final key size is 256 bits, see more about the key under "Key management". The algorithm is very safe, and is widely used in commercial applications like Netscape, Lotus Notes, Oracle, Apple Security, Web SSL, and so on.
Safer SK-128:
This is an extremely safe algorithm, often mentioned as "military strength". I don't like these terms myself, but agree with the experts that this is the choice if you have something really sensitive to protect. The program uses a 128-bit Safer, programmed in C++.
Secure hash algorithm (also known as Secure hash standard or SHS). This is a one-way hash function, often called as a message digest function. Its purpose is to create a small encrypted sequence to be used for checksums, digital signatures, and encryption keys. I use it for both checksum and final key generation. It is very fast, in part because it is programmed in C++. See more details about the key generation under "Key management".
A very important question in encryption is called "Key management". Basically what it means is that no matter how strong your algorithm is, it is worthless if you don't protect the password.
Encrypt-it! uses several steps to make sure that the key is secure:
1. When you enter the password, it is not used straight in the algorithm. Instead, it is converted into a highly uniform binary sequence using the SHA one-way hash function (see "Algorithms"). This way, even if you use a simple password like "NikonF5", it is scrambled. At the conversion all 256 possible ASCII characters are used at the same probability, to make the key more secure.
2. The password and key are never stored in the header of the files.
3. There are some file-specific bytes added to the password (like file size, file date), and then they are processed through the SHA together. This way, even if you use the same password for all of your files, the final encryption key will be totally different for the individual files. This makes the job of a potentional hacker extremely hard!
4. If the Caps lock is accidentally on when encrypting, you can enter a password by mistake that you won't be able to guess next time. Encrypt-it! detects the state of the Caps lock button, and warns you if it is on at the password entry dialog.
1. Select the file you want to encrypt.
2. Check "Delete original" if you want to delete the original file after enrypting it. Of course, you can get back the file by decrypting the scrambled version.
3. Select the required file type. This will affect Quick Update. Leave on standard if you are not sure.
4. Select the required encryption mode.
5. Select the desired "Action when done".
6. Click on "Go!" or press Enter.
7. Enter the password (5-16 characters). Re-enter it in the bottom line. If the Caps lock button was on, you are warned. Press Caps lock to turn it off (the warning won't change once you are inside the dialog).
8. Press "Enter".
The original filename will be used for the new file, only a # sign will be added to the filename.
NOTE: The Quick Update function does not do anything at the encryption step even if you selected it, read under "Quick Update" how to use it.
Don't try to encrypt a file that has a # sign at the end of the filename. Encrypt-it! will try to decrypt these files. If you have such a file and want to encrypt it, please rename it first (replace the # with something else).
A good encryption is relying very much on you. Please don't use too short passwords, and passwords that are very easy to guess by people who know you. Try to create a password containing special characters (numbers, signs like $#%^@!*<~{, alternating capitals and lower case letters, etc.). The program is prepared to the case if you use the same password on more than one file (see "Key management"), but to get the best results use a unique password each time!
Don't forget the password! If you forget it, nobody can help you to recover your file.
Also, before the first real use test the program if it works on your machine perfectly. Do this: create a dummy Word file, then encrypt it. Delete the original file, then decrypt the scrambled version. If you get back the same Word file, then everything is OK. If not, then please contact me immediately.

Since you are reading this help file, you probably succeeded with the installation. :-)
One important note: because a different encryption system is used in version 2.0 and above, the file format has changed. A decrypt utility is included with the program, this can decrypt all your files encrypted with versions 1.2-1.5. I recommend you to decrypt all your old files using this utility, then encrypt them using the new version of the program. If the program finds an old file later, it will launch this decrypt utility on demand.
1. Select the file you want to decrypt. It will be a file with a # sign at the end of the filename.
2. Check "Delete original" if you want to delete the encrypted version of the file after the original file is re-created.
3. You don't have to change the "File type" and the "Encryption mode", because they are read from the file header. Their actual state is indifferent.
4. Select the desired "Action when done". If you select "Quick Update", then the file will also be launched after decryption, then encrypted again. Please read under "Quick Update".
5. Click on "Go!" or press Enter.
6. Enter the password (5-16 characters). Make sure that you enter the password that you used to encrypt the file.
7. Press "Enter".
This mode will hopefully save you a lot of time. Select it from the main dialog, and then the Batch mode file selector dialog will appear. Select a file or folder, and press "add file" or "add folder" to add it to the list. You will see the name of the file(s) that are added to the list. Note: if you add a folder, all files in the folder will be added to the list, but subfolders are not added.
In the dialog you can follow the number of files and their added size. You can select up to 100 files altogether, even encrypted or decrypted files at the same time.
When you added all the files, press "Done" and a second dialog will apear. Enter the password, select if the originals should be deleted, select the encryption mode, and select the "action when done". Quick Update is not selectable, because there is no way updating 100 files at once. :-)
Note: make sure that all the files that you encrypt are of the standard type. You can't individually specify Html or JPG or VReader5 files, all files will be encrypted as "standard".
When ready, press Go! and the list will be processed. If the program finds an open file (opened in Word, etc.), it will give you a note and bypass the file. The progress indicator will show the cumulative progress, not the progress of individual files. The processed filename is also displayed.
This way, you can easily encrypt / decrypt (even mixed) many files at once.
The file types supported by the Quick Update module are listed inside the module. To see them locate the Encrypt folder from the system screen, and click on the file "qupdate.opo". Here you can check its version and date. Press enter, and you will see the supported file types.
Note: If you want to use these file types with Quick Update, be sure to select them at the "File type" box when encrypting.
See also "Launching special file types".
To read encrypted text, e-text and opl files you can now use Jean-Luc Damnet's excellent VReader5 linked with Encrypt-it!
Select "VReader5 document" as the file type upon encrypting. From now on the file header contains this special tag, and you can read the files easily using the Quick Update function. Even better, the files won't be recrypted since these documents are not modified, saving you time.
Note: If another copy of VReader5 was already running, it will be closed for safety reasons.
VReader5 won't allow you to open a different file when you read the file passed by Encrypt-it. Moreover, it will display the icon of Encrypt-it!, and by clicking it you can easily recrypt the file.
When you select special file types in the main dialog as "File type", they will be launched as follows:
Text files: If you select the file type as text, it will be launched using Word. The entire process: the file is decrypted, then the text file is temporarily copied to c:\. A temporary Word file is created in c:\system\temp\, and the text file is imported into Word. Now you can read it. If you make changes, it is important that you have to save the changes manually, because exiting Word does not save changes to the text file. Use the "Export as text file" option in Word to save changes to the temporary test file in c:\. Now as you exit Word, the temporary text file will be moved back to its original location, then it will be recrypted.
VReader5: You can load text, tcr, opl and other e-text compatible files into VReader5 this way. See also "VReader5 support".
S5Zip/RMRZip: The file will be loaded correctly into the Zip program even though regular zip files don't have a Psion file header.
HTML: Html files are loaded into HTMLEdit, but you can aso specify them as text file, and then they will be loaded into Word for editing as described above.
Picture: You can load JPG, MBM, BMP, GIF, TIF and other image files into MBMView this way. The process is very similar to that described for text files.

The encrypted file contains the header of the program itself. So if you are not inside of the program, and locate the file on the system screen, you can quickly decrypt it. Just press enter on the filename or tap two times with the stylus, and the file will launch Encrypt-it! The main dialog will be bypassed, bringing you instantly to the password dialog.
NOTE: The decryption will be performed using the settings of the Preferences file. E.g. if you want to Quick Update every time you use the Quick Decrypt function, open the program from the Extras bar, and click "Quick Update" in the Preferences dialog.
However, a small box is shown where you can change you mind and not perform a Quick Update if you don't want to.
Also, a notice is given if you have the "Close launched files automatically" option enabled in the Preferences dialog. A box is shown to temporarily disable it.
How to Register/
Peter Csutora
v3.0:
* The dialogs are now correctly displayed on the smaller screen of the Psion Revo, too.
* If you wish, the program can automatically compact Data files prior to encryption to keep these files tidy. This option can be turned on in the Preferences dialog (default=off).
* For added security, after a specified time the program will close the document that it has launched before via Quick Update. Great option if you launch a document just to look up something, but forget to close it. This option can be turned on and the delay adjusted in the Preferences dialog (default=off).
* Encrypt-it! can now launch text files by automatically loading them into a Word file. For this option set the file type to "Text file" in the main dialog.
* TomeRaider files are recognised by the Quick Update routine. Create huge personal databases with the TomeBinder package, then encrypt them. Quick updating these files is reasonably fast, a 1 MB file takes 9 seconds to decrypt and launch (Series 5mx).
* The default file type can now be set in the Preferences. Useful if you work with e.g. VReader5 files 90% of the time.
* The program now starts slightly faster. Tip: when using Quick Update you don't even have to wait for the password entry dialog to appear, you can start typing the password right after you click on the file.
The password will be there by the time the dialog appears.
This function means: Decrypt - Open - Recrypt if changed.
Basically, if you store your phonebook or agenda in an encrypted form, this is your function. Select "Quick Update" in the "Action when done" selector box, and pres"Go!". After the file was decrypted, the file will be opened by the application that created it, and you can make the modifications. When you are done, exit the application, and the file will be encrypted automatically using the same password. The decrypted version will always be wiped then deleted.
If you did not make any modifications to the file, it won't be recrypted, since you already have that version. This will save you lots of time.
The Quick Update function also works in the "Quick Decryption" mode, where you run Encrypt-it! by clicking on the file at the system screen.
NOTES: The "standard" file type setting applies to all recognized file types (see under "File types"). To S
use Html, JPG, GIF, MBM, text or VReader5 files please select one of them as the file type at the encryption step.
If a file has no Psion header, and you try to run Quick Update, a short error message will appear saying "Record is too large", and you will be moved back to the main screen.
Quick Update does not work on not encrypted files, for obvious reasons.
Also note that Encrypt-it! is waiting for the completion of the application that it has launched. Until you close the application, you can't use Encrypt-it! directly to process any other file. Also, never open a new file from the application launched by Encrypt-it!, because upon exiting Encrypt-it! won't be able to recrypt the file this way.
If you need to know what application is Encrypt-it! waiting for, just switch to Encrypt-it! (task list), and it will tell it to you.
An added security feature helps you if you often forget to close documents that you launched just to look up something. Select the option "Close launched files automatically" in the Preferences dialog, and specify a delay in minutes. The program will monitor the elapsed time, and if the document is still open, it will close it. Note, that it will close it even if you are actively using that document, and are typing something into it. Use this feature with care, otherwise you will have to launch the document again.
Use the preferences dialog to set the defaults you use most. Please note that these settings are also used if you start the program by clicking on a file (see "Quick Decryption").
Initial file folder: Please select the folder name where you want initially to look for files.
Delete original file: Select it if you want the program to wipe then delete the original file after encryption, or the encrypted file after decryption. Note: when you do a Quick Update, the decrypted (and only temporarily used) file wil always be wiped then deleted.
File type: Select which file type you want to be displayed in the main dialog by default. Useful if you are encrypting e.g. VReader5 files 90% the time.
Encryption mode: Select the default encryption mode.
Action when done: Select your favourite, but don't forget that this also affects the Quick Decrypt mode.
Beep: The program will beep after encryption or decryption. The volume will be same as the volume at the main control panel of your Psion. Select the beep type you like.
Compact Data files: If checked, the program will automatically compact Data files prior to encryption to keep these files tidy. This option uses some extra processor power, but is worth if you frequently edit large Data files which can grow huge in size without compacting them.
Close launched files automatically: If enabled, files launched by Quick Update will be automatically closed after the delay that you select below, under "How many minutes after launch". This feature is great if you often forget to close documents and they are just sitting open in the background, compromising security. See also "Quick Update".

v3.0:
* Full Revo compatibility.
* Automatic compacting of Data files.
* Closing of launched files after a delay time for added security.
* Launching of text files via Word.
* Support for TomeRaider files.
* Setting of the default file type in the Preferences.
* Even faster startup time.
* The program is now marketed through Pocket IQ, the successor of Palmscape (new logo and shared files).
v2.1:
* New Palmscape shared files and logo.
* These shared files can now reside on drive D: as well.
* Other minor changes and improvements.
v2.0:
* This is a really major upgrade! Both the speed and the security are greatly improved. The new algorithms featured are a 256-bit RC-4WA and a 128-bit Safer SK. The key management is now even more secure due to the use of the Secure Hash Algorithm message digest (one-way hash) function. Encrypt-it! is now the highest security encryption utility ever featured on a Psion palmtop!
* All the algorithms were programmed in C++ to maximize their speed. They are enclosed into an OPX file. The speed of the algorithms is 90 kB/s for the RC-4WA and 52 kB/s for the Safer SK-128 (measured on a 1.5 MB file). This means that a typical file of 30 kB is done in less than 1 second!
* Because of the new algorithms the file structure has changed. There is a Decrypt utility included for files encrypted with a previous version of the program. This utility is automatically launched when the program finds such a file.
* Files are securely wiped from the disk before deletion (there was only a partial wiping before).
* The program detects the state of the CAPS lock button, and if it is on, a message is displayed in the password entry dialogs.
* Extended technical section in the Help file.
v1.5:
Quick Update file definitions in a separate file to ease upgrading. Splash screen not displayed for registered users.
Quick decrypt/update can be chosen when starting a file from the system screen.
v1.4:
Batch mode, up to 100 files. JPG and MBM support through MBMView. Other small changes.
v1.3: Html support through HtmlEdit98. Progress indicator window had a major facelift. The program is now marketed by Palmscape. Changes to the task list display.
v1.22: New file types: Easynote, PsiList, S5Task, S5Fuel and S5Notes.
v1.2: The file format has been changed. 500-700% speed increase. Filetype recorded in the header. Smart Quick Update: it only decrypts if the file had been changed. Password size limited to 16 characters. The file is now decrypted into the folder where its encrypted version is located. New file types for Quick Update: Concept!, Timeplan, Plan, MyCar, S5Bank, ABP, PsiBio.
v1.1: Cooperation with Jean-Luc Damnet's excellent VReader5. New file types added: Sketch, Record, Comms, DP5Bank, Statistics and Chess. "Go!" button in the main dialog replaces encrypt/decrypt buttons. The # sign is now added to the filename.
v1.0 final: Quick Update for Data, Word, Sheet, Agenda and Program files. 300% speed increase. Preferences dialog added. Two encryption modes, high and low security type.
v1.0 beta3: Quick Decrypt. Password masking under 16 characters. Password checking (checksum). The file format has been changed.
v1.0 beta: First release: Dec 26, 1997

If you use Quick Up
date, be sure that you don't open any files using File>Open from the application launched by Encrypt-it! If you do so, Encrypt-it! can't get back th control upon exiting the application, re-encryption is not possible, and Encrypt-it! looks frozen.
In this case, you have to "kill" Encrypt-it! To do it switch to it (Extras bar or task list), then press Ctrl+Esc. The program will terminate.
