Public Overrides Function GetBytes() As Byte() is obsolete

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Public Overrides Function GetBytes() As Byte() is obsolete: Rfc2898DeriveBytes replaces PasswordDeriveBytes for deriving key material from a password and is preferred in new applications.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

Solution

  • 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.
