What is Safe Pad

SafePad is a simple FREE text editor that lets you encrypt your documents using strong AES encryption (Advanced Encryption Standard). To protect your document you have to provide 2 passwords (The 2nd password is optional). Passwords have always been a problem when it comes to security as users tend to pick a password that is easy for them to remember. This also means that the password is most likely easy to crack. By using 2 passwords and performing multiple iterations of encryption, it makes it much harder to crack the passwords. If someone manages to crack password 1, all they will get back is encrypted text, so it would be very hard to them to know they have cracked that password.

Main Screen

Safe Pad is a very simple program to use. The main screen resembles a normal text editor like notepad or word-pad. Safe Pad has been designed to be familiar and easy to use. The majority of the main editing controls are contained on the tool bar at the top of the screen.

The tools bar buttons are as follows (from left to right):

    • New Document : Creates a new document. You will be prompted to enter a password for the document.
    • Open Document : Open up a saved document. You will be prompted to enter a password to open the document.
    • Save Document : This will overwrite the document with the current saved password. If you want to save with a different password, use the ‘Save As’ option from the File menu.
    • Print Document : This will send the document to the printer.
    • Cut : Cut out the selected text and save into the clipboard.
    • Copy : Copy out the selected text and save into the clipboard.
    • Paste : Paste the contents of the clip board to the current cursor position in the document.
    • Undo : Undo the last set of actions on the document.
    • Redo : Redo the last set of actions on the document.
    • Font Selection : This drop down box lets you select a new font to use. If you have text selected, then this will change the font of the current text selection.
    • Font Size : This drop down lets you change the font size of the current font or of the current selected text.
    • Bold : Change the current font or text selection to bold.
    • Italic : Change the current font or text selection to italic.

    • Left Justify : Justify the selected text to the left.

    • Right Justify : Justify the selected text to the right.

All of these editing functions besides the font selection and font size are contained on the document context menu which can be access by right clicking the mouse in the document area.

Browse to Hyper Link

If you have any web addresses (URL’s) in your document you can browse to them in your default web browser by selected the link text and right clicking on it to bring up the context menu. If the selected link is a valid link, then you will see a ‘Browse’ option. Select Browse to open up the link in your default browser.

Find and Replace

If you need to search for text in your document, or replace text you can do so from the Find and Replace dialog box. This is accessed from the Edit Menu. To find text in your document you just enter a phase into the first text box and hit the Find Next button. This sill locate the first occurrence of the text in the document. To search for any other occurrence you just hit Find Next again.

If you want to replace any text in the document, first enter the text you want to find in the first text box, and then type the text you want to replace in the 2nd text box. Then hit the Replace button to do the replacement. If you want to match the case of the text you are finding, you can select the Match Case option. If you want to match a whole word instead of a string that is part of a work, you can select the whole word option.

Changing Fonts and Colour

As well as using the main tool bar to change the font and font size, you can use a more detailed set of windows to do the same thing. To change the font colour, open up the View menu and select Select Color. This will bring up the window shown below.

Password Entry

When you create a new document, save a document, or load a document, you have to enter a password. You can also use a 2nd optional password. When you create a new document or want to save a document with a new password you have to entered the passwords twice to confirm them.

It is very important that you do not forget the password(s) that you set for a document. If you forget them, then the document becomes unrecoverable. There is nothing you can do to access the document, except try and remember the password(s).

As you enter each password, you are presented with a password strength meter. Ideally you want to aim for ‘very strong’ password. This will contain a combination of mixed case letters, numbers and punctuation. The password meter in Safe Pad also has a black list of common passwords and their variations. All passwords in this black list will be set to weak security.

On Screen Keyboard

An often requested feature of Safe Pad was an on screen keyboard for password entry. The reason people requested this, was because they were worried about potential keyboard sniffers that may have been installed on their systems. When you are on the password entry screen, you will see a square with 3 dots in next to each password box. If you click on this button, you will get a keyboard like that shown below.

This allows you to use the mouse to enter the password, or a touch screen if you have one. This will build up the password without sending any keyboard events.

Properties

On the File menu you can access the application properties. This is where global properties are stored. Currently there are only a few available.

    • Detect URLs in the document : This setting tells the editor whether to turn URL’s into click-able links. If you decide you don’t want URLs to be click-able, then you can still select the URLs, right click in the document and select Browse.
    • Word Wrap : This option enables or disables word wrapping in the document.
    • Clear Recent File List : This button will clear out the recent file list on the file menu.

Privacy Mode

The primary focus of Safe Pad is to securely store your documents. This is done using strong FIPS compliant AES encryption where the passwords are run through a Password Based Key Derivation Function to create the encryption key. This is all well and good, and secure, but it doesn’t guard against people looking over your shoulder whilst you are writing your document.

Low Contrast Screen Filter

Safe Pad offers 2 low contrast themes that you can enable. These low contrast themes makes it harder for someone standing behind you or to the side to see the text on the screen.

Safe Pad Dark Theme

There are 4 default themes available and they are all accessible from the Theme drop down menu or via keyboard short cuts. These themes, and keyboard short cuts are:

    • Normal : CTRL + F1 – This is a normal editing mode, of a white background and black text.
    • Invisible : CTRL + F2 – This colours both the text and background to white. This is useful if you want to quickly make your text disappear if someone is watching you type.
    • Low Contrast (Dark) : CTRL + F3 – This turns the background to a dark grey and the text to a slightly lighter grey (See screen shot above). This means you can still write your document, but it is harder for people near you to see what you are writing.
    • Low Contrast (Light) : CTRL + F4 – This turns the background to a light grey and the text to a slightly darker grey (See screen shot below). This means you can still write your document, but it is harder for people near you to see what you are writing.

One thing to bear in mind is that these options will loose any colouring to your text in the document. This are more like panic modes to obscure the text you are working on.

Quick Minimize

If you are working on a document and someone is standing near by, you can either change the document theme as described above, or you can hit the Escape key which will quickly minimise the whole application.
