How far can i push close-source code towards being "private and secure"?
im familiar with Kerckhoffs principle and the importance of transparency of implementation when it comes to cryptography, but as a thought excersise, i want to investigate how far i can go with close source. i notice there are big players in the field of secure messaging that are close-source and …
For anyone already going to RWC in March, you can swing by FHE to learn about homomorphic encryption too. Fees are waived for students.

How much of Coding Theory needs to be learnt for understanding Post-Quantum Algorithms (like McEliece etc) based on Codes?
I don't know Coding Theory at all - not even Hamming Codes. I know pre-Quantum Asymmetric systems reasonably well & I also understand Abstract Algebra reasonably well. I was trying to look up Coding Theory & it seems like a separate subject by itself. Is everything in the whole of …
NIST STS questions and use with encrypted data
**Hello cryptos.** I'm testing output of an encryption algorithm and would like to know if a test collection of STS results of a very high quantity will be meaningful. My test plan that I'm running right now... 1. Creation of 803 cleartext samples across 7 groups: * **RepetitivePatterns** * These …

Is magic wormhole safe?
I have a silly question about PAKE protocols often lauded here. Magic wormhole uses SPAKE2 algorithm. The passphrase has 16 bits entropy, from which a secure key is derived. The file is available for download for 24 hours in the relay server. Cannot attacker guess that weak password in 24 …
