Base64 Encryption Question

I have a spec that calls for a Base64 encrypted password to be passed
to a web service.
I have poked around Convert.ToBase64 but am at a total loss on how to
do this.
Made more complicated is that the password is part of a complex data
type class.

What I am trying to do is something functions like this below
(replacing FOO code with something that works) Any help is greatly
appreciated:

Public Property password() As String

'******** start totally FOO code: ************

Dim xRawString as string
Dim xEncryptedString as string

xRawString = "MyPasswordString"

xEncryptedString = SomehowConvertToBase64(xRawString)

'******** end totally FOO code: ************

Get
Return xEncryptedString
End Get

Set(ByVal value As String)
Me.passwordField = xEncryptedString
End Set

End Property
 
Base64 encoding is not an encryption method , it is just a way of converting
binary data into text ( e-mail progs use it for instance to onclude images
in a message )
the encode and decode base 64 classes can be found in the text namespace
and is pretty straigforward in use

As Michel pointed out, Base64 is not encryption. It's just encoding.

The Convert.ToBase64String method takes a byte array, so if you have a
string as input, you have to first encode it into binary data.

What encoding does the web service expect? ASCII? UTF-8? Latin1?

Here is an example using UTF-8 encoding:

base64Encoded = Convert.ToBase64String(Encoding.UTF8.GetBytes(password))

Goran,
Thanks much. Now I understand this and your line of code made it work
for me.
