# Selenite
[](https://app.travis-ci.com/AtropineTears/Selenite)
An experimental rust crate for **Post-Quantum Code-Signing Certificates**.
All Digital Signatures are **Round Three NIST Post-Quantum Candidates** which are listed [here](https://csrc.nist.gov/Projects/post-quantum-cryptography/round-3-submissions).
Please read the [documentation](https://docs.rs/selenite/0.2.1/selenite/crypto/index.html) for usage.
## Overview
**Digital Signatures:**
* SPHINCS+
* FALCON512 and FALCON1024
* ED25519*
* BLS*
\*: Not Post-Quantum Cryptography
## Example Usage
### SPHINCS+ (SHAKE256)
Read [SPHINCS+](https://sphincs.org/)
**SPHINCS+** is a Stateless Hash-Based Signature Scheme taking its cryptographic assumptions against Quantum Computers from cryptographic hash functions.
This Digital Signature implementation reaches a **Security Level of 5**, which is the most secure a signature can be, by using the hash function **SHAKE256** and setting other security parameters. However, SPHINCS+ has slow verification time compared to other choices.
* **SPHINCS+ Version:** sphincsshake256256srobust
* **Public Key Size:** 64 bytes
* **Private Key Size:** 128 bytes
* **Signature Size:** 29,792 bytes
```rust
use selenite::crypto::*;
fn main() {
// Generates The Respected Keypair
let keypair = SphincsKeypair::new();
// Signs The Message as a UTF-8 Encoded String
let mut signature = keypair.sign("message_to_sign");
// Returns a boolean representing whether the signature is valid or not
let is_verified = signature.verify();
}
```
### FALCON512/FALCON1024
Read [FALCON](https://falcon-sign.info/)
FALCON is a lattice-based signature scheme whos underlying problem is based upon the short integer solution problem (SIS) over NTRU lattices, for which no efficient solving algorithm is currently known in the general case, even with the help of quantum computers. Falcon512 is similar in classical security assumptions to the security of RSA2048.
* **Public Key Size:** 897 bytes | 1793 bytes
* **Private Key Size:** 1281 bytes | 2305 bytes
* **Signature Size:** 660 bytes | 1280 bytes
```rust
use selenite::crypto::*;
fn main(){
// Generates FALCON512 Keypair
let keypair = Falcon512Keypair::new();
// Generates FALCON1024 Keypair
let keypair2 = Falcon1024Keypair::new();
// Signs The Message as a UTF-8 Encoded String using the first keypair (FALCON512)
let signature = keypair.sign("Message1");
// Returns a boolean representing whether the signature is valid or not
let is_verified = signature.verify();
}
```
### ED25519
ED25519 is an elliptic-curve based digital signature by DJB that has small public keys, private keys, and signatures.
It is not post-quantum secure but has been included in this library.
* **Public Key Size:** 32 bytes
* **Private Key Size:** 32 bytes
* **Signature Size:** 64 bytes
```rust
use selenite::crypto::*;
fn main(){
// Generates ED25519 Keypair
let keypair = ED25519::new();
// Signs Message
let signature = keypair.sign("Message1");
// Returns a boolean representing whether the signature is valid or not
let is_verified = signature.verify();
}
```
### BLS Signature
BLS is a pairing friendly elliptic curve that allows aggregation of signatures. Aggregation of signatures allow you to combine multiple signatures into a single one. Selenite supports aggregation (although it is still in the works).
```rust
use selenite::crypto::*;
fn main() {
let keypair = BLSKeypair::new();
let keypair2 = BLSKeypair::new();
let signature = keypair.sign("This message is being signed by BLS");
let signature2 = keypair2.sign("This message is also being signed by BLS");
let is_verified = signature.verify();
}
```
### Serialization
You can **Serialize** keypairs to YAML using serde-yaml.
```rust
fn serialize(){
// Generates Keypair
let keypair = SphincsKeypair::new();
// Serializes Keypair To YAML
let yaml = keypair.serialize();
// Deserializes Keypair To Respected Struct
let keypair_from_yaml = SphincsKeypair::deserialize(&yaml);
}
```
```rust
fn serialize_signature(){
// Generates Keypair
let keypair = SphincsKeypair::new();
// Generates Signature
let signature = keypair.sign("Hello World!");
// [BINCODE] Serialize To Bincode
let bincode: Vec = signature.serialize_to_bincode();
// [YAML] Serialize To YAML
let yaml = signature.serialize();
}
```
### Randomness From CSPRNG
Selenite allows you to easily get secure randomness from your operating system.
```rust
use selenite::random::OsRandom;
fn main() {
let randomness_32 = OsRandom::rand_32.expect("Failed To Get Randomness");
let randomness_64 = OsRandom::rand_64.expect("Failed To Get Randomness");
let randomness_128 = OsRandom::rand_128.expect("Failed To Get Randomness");
}
```
### Create SPHINCS+ Certificate
```rust
use selenite::crypto::SphincsKeypair;
use selenite::certificate::*;
fn main(){
let (cert,keypair) = SeleniteCertificate::new(
String::from("Subject Name"),
CertificateType::INDIVIDUAL,
Some(String::from("[Optional] Username")),
vec![KeyUsage::CODE_SIGNING,KeyUsage::DOCUMENT_SIGNING,KeyUsage::REVOCATION],
Some(String::from("[Optional] Email Address")),
Some(String::from("[Optional] Phone Number")),
Some(String::from("[Optional] Address")),
Some(String::from("[Optional] Backup Email")),
Some(String::from("[Optional] Backup Phone Number")),
Some(String::from("[Optional] Description")),
Some(String::from("[Optional] Website")),
Some(String::from("[Optional] @Github")),
Some(String::from("[Optional] @Reddit")),
Some(String::from("[Optional] @Twitter")),
Some(String::from("[Optional] @Keybase")),
Some(String::from("[Optional] Bitcoin Address (BTC)")),
Some(String::from("[Optional] Ethereum Address (ETH)")),
Some(String::from("[Optional] Monero Address (XMR)")),
Some(String::from("[Optional] Zcash Address (ZEC)")),
Some(String::from("[Optional] PGP Key")),
Some(String::from("[Optional] Onion Website")),
Some(String::from("[Optional] Backup PGP Key")),
Some(0usize), // (Optional) | Last_Bitcoin_Block_Height,
Some(String::from("[Optional] Last Bitcoin Block Hash")),
);
}
```
