Elliptic curve cryptography

Mirage-crypto-ec implements public key cryptography with named elliptic curves. Ephemeral key exchanges with Diffie-Hellman and digital signatures (ECDSA) are implemented.

The arithmetic operations uses code generated by fiat-crypto which is proven to consume a constant amount of time, independent of the input values.

type error = [

| `Invalid_range
| `Invalid_format
| `Invalid_length
| `Not_on_curve
| `At_infinity
| `Low_order

]

The type for errors.

val pp_error : Format.formatter -> error -> unit

Pretty printer for errors

exception Message_too_long

Raised if the provided message is too long for the curve.
