Unique way to encrypt a file. I have posted an example of this, put this here just in case people did not feel like downloading it. This is my first encryption method. Wanted to make one that no other method used. So I came up with this. Please leave comments to let me know what you think of this, like I said it is my first so I would really appreciate some feedback. Thanks.
VBcodersPublic Function Encrypt(StringToEncrypt As String, Optional AlphaEncoding As Boolean = False) As String
On Error GoTo ErrorHandler
Dim Char As String
Encrypt = ""
For i = 1 To Len(StringToEncrypt)
Char = Asc(Mid(StringToEncrypt, i, 1))
Encrypt = Encrypt & Len(Char) & Char
Next i
If AlphaEncoding Then
StringToEncrypt = Encrypt
Encrypt = ""
For i = 1 To Len(StringToEncrypt)
Encrypt = Encrypt & Chr(Mid(StringToEncrypt, i, 1) + 147)
Next i
End If
Exit Function
ErrorHandler:
Encrypt = "Error encrypting string"
End Function
Public Function Decrypt(StringToDecrypt As String, Optional AlphaDecoding As Boolean = False) As String
On Error GoTo ErrorHandler
Dim CharCode As String
Dim CharPos As Integer
Dim Char As String
If AlphaDecoding Then
Decrypt = StringToDecrypt
StringToDecrypt = ""
For i = 1 To Len(Decrypt)
StringToDecrypt = StringToDecrypt & (Asc(Mid(Decrypt, i, 1)) - 147)
Next i
End If
Decrypt = ""
Do
CharPos = Left(StringToDecrypt, 1)
StringToDecrypt = Mid(StringToDecrypt, 2)
CharCode = Left(StringToDecrypt, CharPos)
StringToDecrypt = Mid(StringToDecrypt, Len(CharCode) + 1)
Decrypt = Decrypt & Chr(CharCode)
Loop Until StringToDecrypt = ""
Exit Function
ErrorHandler:
Decrypt = "Error decrypting string"
End Function
