Should I seed a SecureRandom?

Question

Found the following code in our code base:

public static final int DEFAULT_LENGTH = 16;
private static SecureRandom SR;
static
{
   try
   {
      SecureRand         


        

Answer 1

Just an addendum to this answer. According to Google, if you are using this code in android you should definitely seed the SecureRandom using a high entropy source like /dev/urandom or /dev/random.

Even the post below is an year old now, perhaps this has already been corrected but I couldn't confirm if it was.

EDIT:

It seems that the default behavior of the class is now the one specified in the post so seeding is again deemed unnecessary:
