Disclaimers and correction to above wget script

In reply to: Wgetting bytes from by pr1268
Parent article: Appropriate sources of entropy

Standard disclaimers and a correction:

  1. I claim no liability whatsoever for whatever happens if anyone runs the above script on their computer. Granted, I have tested it on Slackware 12.0, and it appears to work fine.
  2. imposes a quota (based on client IP address) for fetching entropy bits from it. Please be mindful of this, as I do not want to blamed for others being denied access due to overuse.
  3. I seem to have misspelled the last query parameter name. According to's HTTP interface specification, it should be rnd= instead of md=.

The value of the num= query parameter specifies how many bytes are provided. I'm unsure whether 8 bytes (64 bits) would be preferred for 64-bit Linux users (anyone 64-bit user out there wish to comment on that?).

Finally, my apologies for sounding like a shill, but there are some really good articles and links on entropy and randomness there.
