Encryption password can be zero or more characters long.
All leading and trailing spaces are ignored and removed.
The password is case sensitive, so PASSWORD and password will give you different results.
The longer the password is, the harder it is for someone to workout the password.
The different code versions are incompatible with each other, see below.
You should only use space (Character 32) to ~ (Character 126) as other characters are either, control characters or foreign letters not available on all keyboards.

The message text can be any text you wish.
When encrypted / decrypted any control characters will not be altered. (EG. Characters under 32, such as line-feeds)

Version 0.00.0001 and 0.00.0002 will convert all characters including characters above 127.
Characters above 127 may not copy, paste and/or save correctly with some programs.

Ticked = Don't convert to any top-bit characters.

• Ticked = The top-bit is lost and characters 128 to 255 are converted to character 0 to 127.
  (If a top-bit character is converter to a control character, then it is converted to ? instead.)
  
• Unticked = Characters can be converter to/from characters above 127. Use this option if;
  You want to decrypt a message that was encrypted with version 0.00.0001 or 0.00.0002.
  You want top-bit characters in your message. EG. €, Ċ, ċ, Ġ, ġ, Ħ, ħ, Ż, ż
  

Recommended setting is ticked.

When encrypted, do not add any spaces, characters or line-feeds to the start of the message. If you do then the message will not decrypt correctly.

Data is saved for 5 years, unless deleted with Full reset. See below.

Reset form will clear the message box and reset the password from the stored cookie data.
Reset will also reset the font face, font size and message box height, from the stored cookie data.
Full reset will clear any stored cookie data and reset the display. Your stored password will be lost.

Code versions:
Note:
Different versions will convert the text to a different string.
The different versions are incompatable with each other.
Encrypting text with one version may not decrypt correctly with a different version.


• 0.00.0001 ( 4/07/2016)
  First version, converts all characters, including control characters.
  As some fonts and browsers don't display all characters above 126, some characters above 126 will not be displayed.
  When converting back, some of the non displayed characters, will be incorrectly converted.
  Also copy and paste dose not work correctly with some characters above 126 with some browsers.
  
  
• 0.00.0002 (10/07/2016)
  If password='', then '?' is used as the password.
  Control characters are not converted.
  Any character that will converted to a control character is not converted.
  (Characters 0 to 31 and 127)
  This version will still encrypt/decrypt characters above character 127.
  Characters above 127 will not copy and/or paste into/from some text editors, such as Notepad.
  
  You can copy and/or paste characters above 127 using some word processors, such as;
  
  • Microsoft Word.

  • Open Office.
    
  
  
• 0.00.0003 (20/07/2016)
