About The Position

Keyfactor and the Bouncy Castle team are looking for a Software Engineer/ Cryptography Specialist, to join the open-source cryptography project famous for the use of cartoon spies. You are proficient in either Java or C#, and comfortable in the other. Decent background in mathematics will help. We do not expect a zero-knowledge proof that you are the right person, but if you know what ZKP is, then you just might be.

Position favors someone who is patient, likes solving technical problems, and conquering standards documents. This is a job best approached from the point of view that you will probably never know enough, but there is plenty of scope to learn more. You will contribute to a product that is used by millions of humans and devices out there, hence the ability to patiently communicate with and provide support to non-cryptography versed engineers and users is a necessity.

What is Zero-knowledge?

Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact

In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof

Here are some examples of zero-knowledge:

  1. Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
  2. Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
  3. Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
  4. Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
