I for one, speaking for myself, would not have any reason to do this. Also, given todays technology and technology of the future- I wouldn't go there.
I just posted a message on a "Numbers Relay Page"; for fun and educational purposes. Since I used a shared network, Public Library and my Library Card- that cover is "blown". Same goes for WIFI network. I consider the Internet a unsecured network "period".
Over the Radio, with the logistics involved and need for cohesive organization- forget it. Somebody, somewhere, for some reason is likely to cause compromise.
Although, it's ancient history- case in point, remember Walker the guy who gave the Russians operating and repair manuals and whatnot for KW-7 and KG-13 Cryptomachines? Former Navy Officer. I did field maintainance on both the KW-7 and KG-13; and never saw any of these manuals; evidently the Russians got to read them at there leisure.
I commented on this subject sometime ago and deleted my comments because of the anonymous comments that followed mine; or so he thinks, General Class License isn't? Point is none of this is secure; and these deletions may not be visible, but they are stored somewhere.
Speaking for myself, other than for fun and educational purposes, I for one, would be very carefull. Presently, I'm interested in learning about "Book Encryption" Techniques and musing about how this One-Time Encryption material is physically distributed in the Field. For fun and education.
I would like to point out, that it is my understanding that some governments including the U.S. Government, consider Cryptography Equipment and Techniques as Weaponry. Some of you Guys do that QRPP Beacon Stuff, and perhaps drift off Frequency from time-to-time; however, to my mind this is a whole different Enchilada. It is legal to practice One-Time Encryption on the Internet- just go to a Numbers Relay page. In this day and age I would do nothing that could come back to haunt me- keep it light. Based on my recent experiences of opting out of my Internet accounts especially FaceBook (SUCKS!!!!!); then finally opening another e-mail account; I wouldn't trust these computers any further than I could throw one. I have never owned a Computer in my life- you couldn't give me one; I use the Public Library and presently this malfunctioning piece of crap at Cal Poly University- it's all tracable. LapTops transmit some type of signal that ID's that particular machine when used in a WiFi network or so I'm told.
