This is such an amazing piece. I second this and am very surprised to see it pop up on HN. Way cool! :)

One of my favorite memories is driving far north of Jackson, WY with my partner and her father. We pulled over off the road near a farm and started stargazing when I noticed this colorful ribbon flowing in the sky. I thought it was the Aur

NuCypher uses this on our proxy re-encryption scheme. You don't want a re-encryption key to be all together in one place, so we split it up using SSS and distribute the fragments. For cryptography beginners, this scheme is relatively e

No, sMPC is seen as different from FHE (Fully Homomorphic Encryption). Some protocols utilize the partially homomorphic qualities of certain cryptosystems, e.g. Paillier for additive homomorphism. I view both of these things as methods to p

This is what some people who don't understand any art history say about art. You can often hear this with statements like, "Picasso just drew cubes! Anyone can do that!"

I think it's pretty neat that you have banned imports for md5, rc4, and des, but why not also add SHA1 to the list?

We have a more feature-complete reference implementation of Umbral called pyUmbral you may want to look into[0]. We (NuCypher) are using this to build a blockchain privacy layer in the form of a decentralized key management system similar t

Go supports Bignums, this is true. I love Go's interfaces, but it doesn't support constant time arithmetic for all of the operations[0]. Go also doesn't support all the curves we need (mainly secp256k1). We also have a `Point

Hey, everyone! For some context, here's our blogpost about this pre-release. We're really excited to debut our cryptography arithmetic layer for Go. It's the first step to making our split-key threshold proxy re-encryption li

FYI, 2g is not a safe choice for security. For an introduction to the security issues, take a look at how the encryption can be easily broken: https://link.springer.com/chapter/10.1007%2F978-3-319-28166-...

CTs don't use homomorphic encryption. They use "additively homomorphic commitments" which are, essentially, cryptographic proofs.

I noticed this on your site: > We encrypt all user data on our end with cryptographically secure hash functions. Can you please tell me if you _actually_ encrypt anything? A hashing function is not encryption...

Most definitely this. Bad messenger OPSEC is a real problem, still. Just recently Paul Manafort backed up his encrypted WhatsApp messages to iCloud, for example. Many users of these apps don't realize that they are opening themselves u

I like to use GitHub to find vulnerabilities. I mostly do cryptographic engineering, so when hunting for issues, I search for things that are usually problematic. For example, searching for something like "XOR encrypt" and you mig

Security centric development. I don't think I need to go into the details of why it's useful, but I think nearly every developer should have an idea of very common vulnerabilities and bugs and be able to catch them _before_ code g

I haven't done a lot of research on MeWe (though I have heard of it previously), but many people misuse the term "SSL" to mean "TLS". Before making this assumption, it might be best to check and see if they _actuall
