'this function is the encryption
Public Function Encrypt(ByVal Plain As String)
Dim Letter As String
For i = 1 To Len(Plain)
Letter = Mid$(Plain, i, 1)
Mid$(Plain, i, 1) = Chr(Asc(Letter) + 99)'the 99 is the ascii value changed from password...you can change it to what ever you want as long as it's under 255
Next i
Encrypt = Plain
End Function
'this function is the decryption
Public Function Decrypt(ByVal Encrypted As String)
Dim Letter As String
For i = 1 To Len(Encrypted)
Letter = Mid$(Encrypted, i, 1)
Mid$(Encrypted, i, 1) = Chr(Asc(Letter) - 99)'the 99 is the ascii value changed from password...you can change it to what ever you want as long as it's under 255
