Hello,

  This is my first post on this forum.

    I have to implement the DES and RSA algorithms in C. Those codes
will run on the Smart Card processor, the code should run on
different smartcard processor.
  
  I'm kind of new to critography, I've read a little of the Applied
Cryptography book, I've read the DES alghoritm.

  

  My problem is, for exmple the DES algorithm, I don't know how to
generate the DES key.

  I'm reading right now the Random number generation alghoritms from
the Applied Cryptography book, but they seem to use a seed, and that
seed I don't know how to generate it.

  Acctually I don't know what alghorithm(with or without seed) to use
for the generation of the DES key.
   The problem is that I can't use some external hardware random
number generator device , or something like /dev/random, nor the
mouse movements... since this code will run inside of the smart card.

 
  Thank you very much!!!
