My last post: https://www.reddit.com/r/Python/comments/1nlvv14/pure\_python\_cryptographic\_commitment\_scheme/ Hello everyone, when I had last posted on r/python, the post named: (Pure Python Cryptographic Commitment Scheme: General Purpose, Offline-Capable, Zero Dependencies) I also posted on other subreddit's and found that I needed to create a …
My textbook *The Joy of Cryptography* is released in print today! Some of you may be familiar with early PDF drafts of the book. The new edition is a complete re-write: the coverage of existing material is greatly improved, and …
This is a small cryptography experiment I’ve been working on. I took the original RSA Factoring Challenge numbers (from the 1990s) and encrypted short messages with them using a fixed public exponent. Each challenge provides: \- the RSA modulus (n) …
Primality testing examples found online all say to first check against "a number of" small primes before invoking Miller-Rabin. For my hobby project in Forth, I've authored a routine to test against the first 97 primes. From 2 through 509, …
As the post says, im struggling to understand the difference between the regular and x25519 diffe hellman functions. For an assignment i need to produce a lightweight crytpographic system that encrypts with a symmetric Cipher and then encrypts that key …
For the sake of argument assume I have 10.000 qubit quantum computer, not via extensive hardware, but with math & algo on a classcial computer. I have reversible engine with both Clifford and Non Clifford gates. Now, how do I …
