Moneroff

❍ An offline Monero key generator & (soon to be) transaction signer in Rust.

 

---

🔧 Build it:

❍ cargo +nightly build --release

Note the use of nightly since we're using the try_trait in order to unwrap options into Results and thus use the ? operator on both in the same fxn.

 

---

🎒 Test it:

❍ cargo +nightly test

📋 To Do:

• Add key generation ability.
• Add CLI arg support w/ docopt.
• Add key set generation from existing.
• Make sensible key type so that sizes are enforced!
• Have way to save and load from encrypted key file(s).
• how does monero encrypt the files (if it does?)
• Make work w/ multiple keys
• Use inquirerjs style menu (rustbox?) for picking which key to sign with.
• Add ability to add/rm keys (make latter require p-word of that key!).

✒️ Monero Notes:

Monero uses the Edwards25519 Elliptic Curve:

−x^2 + y^2 = 1 − (121665/121666) * x^2 * y^2

...which has the chosen base-point G:

G = (x, -4/5)

The prime order l of the curve is also chosen by the curve's authors as:

l = 2^252 + 27742317777372353535851937790883648493

… & so the maximum scalar for this curve is:

7237005577332262213973186563042994240857116359379907606001950938285454250989
