# Ring Signatures 
A ring signature allows a member of a group to sign a message on behalf of the group, without revealing who the actual signer is.
It is used in privacy-focused systems like [Monero](https://www.getmonero.org/) to hide the sender among a group of decoys ([Monero (RingCT)](https://www.getmonero.org/resources/moneropedia/ringCT.html)).
> [!NOTE]
> Implementation of [ring signatures](https://en.wikipedia.org/wiki/Ring_signature) with the [curve25519-dalek](https://docs.rs/curve25519-dalek/latest/curve25519_dalek/index.html) crate using the Ristretto group ([Why Ristretto?](https://ristretto.group/why_ristretto.html)).
# Usage
```shell
Options:
-n, --n Ring size [default: 5]
-s, --signer Index of signer [default: 2]
-m, --message Message to sign [default: "Ring signatures are cool."]
```
For example,
```shell
cargo run -r -- -n 10 -s 2 -m "Ring signatures are cool."
```
outputs:
```shell
Number of Signers : 10
Signer Index : 2
Message : Ring signatures are cool.
