Encrypts text
VBcoders
pass$ = Len(password.Text) 'the number you shift Each letter To encrypt
tmpstr = Len(Text1.Text)
If tmpstr = "0" Then
MsgBox ("You must first Type In something To Encrypt") 'You can't encrypt nothing
Exit Sub
End If
For i = 1 To tmpstr
letter = Mid$(Text1.Text, i, 1) 'takes the ascii value and adds the length of the password To it
encstr = Asc(letter) + pass$
newstr = Chr$(encstr) 'changes ascii value To a character
encrypted$ = encrypted$ & newstr 'puts all the encrypted characters together
Next i
Text1.Text = encrypted$ 'puts the encrypted String in text box
End Sub
Private Sub cmdDecrypt_Click()
pass$ = Len(password.Text) 'this is the exact same For the Encrypt Function
tmpstr = Len(Text1.Text) 'the only difference is that instead of adding the lenght of password.text
'it is subtracted
If tmpstr = "0" Then
MsgBox ("You must first Type In something To Decrypt")
Exit Sub
End If
For i = 1 To tmpstr
letter = Mid$(Text1.Text, i, 1)
encstr = Asc(letter) - pass$
newstr = Chr$(encstr)
decrypted$ = decrypted$ & newstr
Next i
Text1.Text = decrypted$
End Sub
