Subject : Q) SHA(Secure Hash Algorithm) for wireless NDIS driver.

Dear all,

I want to ask you a question about SHA(Secure Hash Algorithm) for wireless
NDIS driver.

It needs to use SHA algorithms because it's spec of that.

At first, I need to derive a new_key using a old_key according to below
statement.

      new_key = SHA(PAD|(old_key))

            old_key : 20 bytes char array. (will be given)
            PAD = 0x3a repeated 64 times.

  There is no more comments for this. I think the above function(SHA) is an
abstract representaion.

Q1) In this case, SHA refer the SHA-1?

Q2) Could you please tell me how to get the new_key little bit more detail?

    What's the SHA function refers? Is it refer the SHA-1? Is it an abstract
representaion?

    Is there any c source codes for the SHA function to create the new_key?

Have a nice day.

Thank you.
