How to Secure your data without any software

Secure your data without any software


This simple HTML application made with notepad can encrypt and decrypt the text entered into a text box using the given password. The encrypted output of the program is in only uppercase alphabet letters and numbers. The draw back of the program is that it will double the length of the string when encrypting.

1. Paste the code given into notepad

<html><head>
<title>TextEncrypt</title>
<HTA:APPLICATION
APPLICATIONNAME="TextEncrypt"
ID="TextEncrypt"
VERSION="1.0"
MAXIMIZEBUTTON="no"
SCROLL="no"/>
</head>
<style>
body {background-color: #000000; color: #808080;}
input {background-color: #101010; color: #808080;}textarea {background-color: #202020; color: #808080;}</style>
<script language="VBScript">
Sub Window_OnLoad
Dim width,height
width=460
height=400
self.ResizeTo width,height
End Sub
Function Validate(ID)
On Error Resume Next
Key = Int(pswd.value)
If (pswd.value = "") Then
X = MsgBox("Enter a password!", 48, "ERROR!")
Else If (boxa.value = "") Then
X = MsgBox("Enter the text to encrypt or decrypt!", 48, "ERROR!")
Else
Junk = SetTimeOut(KEYS(ID), 1)
End If
End If
End Function
Function KEYS(ID)
text = pswd.value
code = 0
Do Until text = ""
code = ((Asc(Left(text, 1)))+code)
text = Replace(text, Left(text, 1), "", "1", "1")
Loop
code = code Mod 255
akey.value = code
Junk = SetTimeOut(ID, 1)
End Function
Function Encrypt
Alph = Array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z")
text = boxa.value
code = ""
key = Int(akey.value)
Do Until text = ""
cnum = Asc(Left(text, 1))
cnum = (cnum+key) Mod 255
num = cnum Mod 26
count = 0
tst = num
Do Until tst = cnum
tst = tst+26
count = count+1
Loop
code = code & alph(num) & count
text = Replace(text, Left(text, 1), "", "1", "1")
Loop
boxa.value = code
End Function
Function Decrypt
Alph = Array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z")text = boxa.value
code = ""
key = Int(akey.value)
Do Until text = ""
lttr = Left(text, 2)
num = Asc(Left(lttr, 1))-65
chk = Right(lttr, 1)
count = 0
Do Until count = Int(chk)
num = num+26
count = count+1
Loop
num = num-key
Do While num <= 0
num = num+255
Loop
Code = code & Chr(num)
text = Replace(text, Left(text, 2), "", "1", "1")
Loop
boxa.value = code
End Function
</script>
<body bgcolor="white">
<input type="hidden" id="akey">
<table align="center" width="400">
<caption><hr><b>TEXT SECURE</b><hr></caption>
<tr>
<td align="center">Password: <input type="password" id="pswd"></td>
</tr>
<tr>
<td align="center"><input style="width: 410px; height:30px;" type="button" Value="Encrypt" id="BTNE" onClick="Validate('Encrypt')" onmouseover="BTNE.style.background='#303030'" onmouseout="BTNE.style.background='#101010'"></td>
</tr>
<tr>
<td align="center"><input style="width: 410px; height:30px;" type="button" Value="Decrypt" id="BTND" onClick="Validate('Decrypt')" onmouseover="BTND.style.background='#303030'" onmouseout="BTND.style.background='#101010'"></td>
</tr>
<tr>
<td align="center"><textarea id="boxa" cols="50" rows="10"></textarea></td>
</tr>
<tr>
<td align="right"><span style="font-size: 10px;">Copyright © 2013</span> | <span style="font-size: 10px;">By - #XByte</span></td>
</tr>
</table>
</body>
</html> 

2. Save as TextSecure.hta. You can name it anything but remember to include the .hta extension while saving.

3. Open the program, enter the text or code and password and click encrypt or decrypt.
