public abstract class DeriveBytes {
// Protected Constructors
protected DeriveBytes( );
// Public Instance Methods
public abstract byte[ ] GetBytes(int cb);
public abstract void Reset( );
}
This abstract class is the basis for implementations that derive byte
sequences from input data. For example, the .NET Framework class
library includes the PasswordDeriveBytes class,
which derives a cryptographic key from an easily remembered password.
The GetBytes( ) method derives a number of bytes
from the input, where the number of bytes to derive is specified as
the methods argument.
