Just for fun - importing binary encrypted blobs into LibreCalc
by Stefan Claas 05 Mar '21

05 Mar '21

Hi all, some of you may remember my binary to words converter at https://github.com/sac001/b2w When Alice saves her encrypted message for Bob, in binary format she simply uses the converter, import the file into LibreCalc and gives the file to Bob. Bob then simply loads the file into LibreCalc and saves then as .csv file and uses sed to replace the commas in the file with blanks, so that he can then convert the file back and decrypt it. https://postimg.cc/R33gpzWq Regards Stefan

PCWorld: Overclock at your own risk: Intel axes its overclocking warranty. https://www.pcworld.com/article/3609834/overclock-at-your-own-risk-intel-ax… Jim Bell's note:I over-clocked a Z-80B (6 MHz spec) to 12 MHz in 1978, cooling it with a thermoelectric device.

Crypto Paper: RSA destroyes vis Schnorr

https://eprint.iacr.org/2021/232 Cryptology ePrint Archive: Report 2021/232 Fast Factoring Integers by SVP Algorithms Claus Peter Schnorr Abstract: To factor an integer N we construct n triples of pn-smooth integers u,v,|u−vN| for the n-th prime pn. Denote such triple a fac-relation. We get fac-relations from a nearly shortest vector of the lattice L(Rn,f) with basis matrix Rn,f∈R(n+1)×(n+1) where f:[1,n]→[1,n] is a permutation of [1,2,...,n] and (Nf(1),...,Nf(n)) is the diagonal of Rn,f. We get an independent fac-relation from an independent permutation f′. We find sufficiently short lattice vectors by strong primal-dual reduction of Rn,f. We factor N≈2400 by n = 47 and N≈2800 by n = 95. Our accelerated strong primal-dual reduction of [Gama, Nguyen 2008] factors integers N≈2400 and N≈2800 by 4.2⋅109 and 8.4⋅1010 arithmetic operations, much faster then the quadratic sieve {\bf QS} and the number field sieve {\bf NFS} and using much smaller primes pn. This destroyes the RSA cryptosystem. Category / Keywords: secret-key cryptography / Primal-dual reduction, SVP, fac-relation Date: received 1 Mar 2021 Contact author: schnorr at cs uni-frankfurt de

Homebrew 8 1/2 Digit DIgital Voltmeter (DVM)Hackaday: Homebrew Metrology The CERN Way. https://hackaday.com/2021/02/26/homebrew-metrology-the-cern-way/ Jim Bell's note:. In 1974, one of my early electronics projects was to design and build a 4 1/2 Digit DVM, including a custom-designed printed circuit board that I laid out and etched. It used a MK5002 counter chip. https://www.datasheetarchive.com/?q=MK5002
