Package hash2curve implements Hashing to Elliptic Curves as specified in [RFC 9380](https://datatracker.ietf.org/doc/rfc9380).

The following table shows supported groups with hash-to-curve capability and links each one to the underlying

implementations:

| Curve        | Backend                        |

|--------------|--------------------------------|

| Ristretto255 | github.com/gtank/ristretto255  |

| P-256        | filippo.io/nistec              |

| P-384        | filippo.io/nistec              |

| P-521        | filippo.io/nistec              |

#### What is hash2curve?

> Hashing to Elliptic Curves allows for encoding or hashing an arbitrary string to a point on an elliptic curve

> (or element in a group), therefore benefiting from interesting mathematical properties very useful in cryptographic

> protocols, like CPace, VOPRF, and OPAQUE.
