Public Overrides Function GetBytes() As Byte() is obsolete

Question

What does the poet try to say?

Public Overrides Function GetBytes() As Byte() is obsolete: Rfc2898DeriveBytes replaces PasswordDeriveBytes for deriving key material from a password and is preferred in new applications.

Should i replace this one...

Dim keyBytes As Byte()
keyBytes = password.GetBytes(keySize / 8)

...with what?

Answer 1

You are missing crucial part of your code. It is that part that declares password to be PasswordDeriveBytes. Change that to Rfc2898DeriveBytes and you are good.

Answer 2

// Constructor needs parameters...fill in with yours
Dim password as new Rfc2898DeriveBytes(yourParamsHere)

Dim keyBytes As Byte()
keyBytes = password.GetBytes(keySize / 8)

Answer 3

sounds like what you need is http://msdn.microsoft.com/en-us/library/system.security.cryptography.rfc2898derivebytes.getbytes.aspx
