...The use of this generator for REAL OTPs is not recommended. For REAL OTPs, hardware-based key generators (e.g. thermal noise of a pn junction, transistor or diode), white noise (e.g. out of tune radio) or other stochastic decay processes should be used. If used correctly, it cannot be decrypted by any intelligence service.

...It automatically forks and runs as a daemon, unless one of the testing options, -o or -t, are selected. Then it never forks. To use it, you need an rtl2832 USB dongle. They are relatively cheap (< $10 on ebay), and are actually used to listen to a broad range of radio transmissions. This application exploits the radio noise in the atmosphere to extract entropy. The kernel already has a module to use the rtl2832 for its intended purpose, listening to radio, so if you want to use it to generate entropy, you will have to blacklist that module, so it doesn't load. If it is loaded, this program will not be able to acquire the rtl2832 device, and won't run. ...

OpenBeacon is a free design for an active RFID device which operates in the 2.4GHz ISM band, containing a unique serial number. OpenBeacon is designed as a transceiver device and therefore both transmits and receives radio waves.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code.
