Contact form problems
22 December, 2025
We know - you’re not supposed to blink text! However…
Due to unfortunate invariant perturbations with email authentication protocols, and entropic effects thereon, some thoughts from the Contact form have been lost to the ether over the last few months. Many sorries 🙁
Full control has now been re-established. If any dear readers are awaiting responses from us, please contact us again and re-share your thoughts. More sorries.

We have pulled ent3000 for the time being as it undergoes some “re-thinking”. It will return shortly in a new guise.
13 March, 2025
v0.6.0-beta of ent3000 is now available. And a slightly newer look to the site. Phew!
3 March, 2024
v0.4.4-beta of ent3000 is now available.
31 December, 2023
v0.4.2-beta of ent3000 is now available. Happy New Year 😃
9 September, 2023
ent3000 source code repatriated from GitHub to here.
14 August, 2023
v0.3.3-beta of ent3000 is available, as well as technical descriptions of its tests.
22 July, 2023
And now v0.3.2-beta is released with rational and QA documentation.
9 July, 2023
Latest v0.3.0-beta release of ent3000, following successful QA testing.

ent3000: A new randomness testing suite for TRNG Makers generating in the sub 1 MB space. Successor to John Walker’s venerable ent. Please try it.
10 February, 2023
New year, new stuff. A piece highlighting the unseen dangers within America’s NIST organisation. And a related, very good read that seems frighteningly familiar.
14 March, 2022
Various re-jiggings of various things, but mainly to the 3 Golden Rules. And an analysis of the entropy coming from the Zenerglass ($ H_{\infty} = 5.5 $ bits/byte).
1 September, 2021
A solution to all of your life’s problems, using our un-biased quantum randomness powered life decision assistant. And some electro-mechanical details of the Zenerglass.
15 July, 2021
Further further electro-mechanical details of our Null Gamma Device, including a view of it running nicely.
10 June, 2021
PGP (GPG) key updated to outwit the Man.
5 June, 2021
Accurate entropy measurement of Photonic Instrument output using a novel chop and stack conditioning technique, resulting in $H_{\infty} = 7.9$ bits/byte or 34.5 46 kb/frame. And also a technique for mitigating the effects of ambient temperature changes.
13 April, 2021
Further mechanical details of our Null Gamma Device, including the I/O PCB. And Zener diode electrical behaviour, reaching the conclusion that $V_Z$ is pretty much unrelated to $H_{\infty}$.
30 December, 2020
An entropy analysis of our covert Type 3 cryptography kit (Mata Hari). We obtain 7.9 bits/byte $(\text{bias}, \epsilon = 2^{-9.5})$ of entropy at a rate of 4.4 kbits/s.

See what Zener diodes look like on the inside.
10 November, 2020
Some initial mechanical details of our Null Gamma Device. The four component entropy source produces a signal spanning 4.7 bits of binary range.
8 October, 2020
Analysis of the latest NIST 800-90B entropy measurement suite @ GitHub. And read about UK’s GCHQ training presentation for new covert operatives (29 MB).
A critique of the ent program vis-à-vis entropy measurement.

26 August, 2020
A response to a long OTP question and some cock-ups, including a cryptographic assessment of FinalCrypt.
14 August, 2020
A treatise on real Truth and pseudo-truth wrt TRNGs and cryptography.
27 July, 2020
The Null Gamma Device is now on stream, with live entropy and a random walk.
