Tripple DES Encrypt/Decrypt string Function or Example

[Peter]

Has anyone made a simple tripple des encryption function?

I'm looking for a function to pass a string into with a password and
generate an encrypted output. That's it.

IE. Public Function EncryptMe (StringtoEncrypt, Password)as string
End Function

Public Function DecryptMe (StringtoDecrypt, Password)as string

End Function

or something to this nature? I know this is not reinventing the
wheel.

Here I found this on the net somewhere. It works as wel
