I am aware [the following site](https://crocs-muni.github.io/ct-tools/) gives a table of constant time verification tools for hardware. What constant time verification tools exist to verify if a hardware implementation of a cryptosystem is constant-time (e.g. FPGA implementation prototyped in VHDL and …
It just occured to me that even businesses outside the US follow US Federal Government standards for cryptography. Proton, Tuta, Nitrokey, and Mullvad are just some of the online privacy services headquartered outside the US that follow US government standards …
[One of the things](https://csrc.nist.gov/projects/post-quantum-cryptography) that struck me about the NIST Post-Quantum announcement is that it takes two decades to ensure adoption of public key infrastructure. It makes me wonder--why does it take so long to influence people to adopt and …
I'm researching group based crypto-systems and I'm trying to determine if I've hit the edge of what is available. I'm basically up to speed on what is covered in this excellent survey: Semidirect Product Key Exchange: the State of Play …
The idea I have is a secure password into Argon2id using NaCl(truncated to 32 bytes), then use NaCl to turn that into a secret key that SSH will happily accept. I have managed to get OpenSSH to accept a key …
I saw Frank Denis (\`libsodium\` author) mention this on social media, stating: \> Until the Keccak or Ascon permutations receive proper CPU acceleration, the AES round function remains the best option for building fast ciphers on common mobile, desktop, and …
For a while now I have been messing around with a custom protocol for a pure P2P encrypted file transfer tool which uses password-based authentication, and was finally able to compile the bits and pieces I developed over a couple …
