Perfectly random one-time pad for encryption

I need to create a one-time pad to encrypt some data (a few KBs in size). How should I go about generating this one-time pad to avoid all of the pseudo-random problems associated with basic random number generation such as rand()?

Is there an existing, trusted tool or library I can use for this?

Solution

  • Try Random.ORG. They have various free (and paid) services that generate truly random numbers based on atmospheric noise (or at least that is what they claim to do).
