Struct p384::NistP384

pub struct NistP384;

NIST P-384 elliptic curve.

This curve is also known as secp384r1 (SECG) and is specified in FIPS 186-4: Digital Signature Standard (DSS):

https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.186-4.pdf

It's included in the US National Security Agency's "Suite B" and is widely used in protocols like TLS and the associated X.509 PKI.

Its equation is y² = x³ - 3x + b over a ~384-bit prime field where b is the "verifiably random"† constant:

b = 2758019355995970587784901184038904809305690585636156852142
    8707301988689241309860865136260764883745107765439761230575

† NOTE: the specific origins of this constant have never been fully disclosed (it is the SHA-1 digest of an inexplicable NSA-selected constant)

impl Curve for NistP384

type FieldSize = U48

384-bit (48-byte)

impl Debug for NistP384

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NistP384

pub fn default() -> NistP384

Returns the "default value" for a type.

impl DigestPrimitive for NistP384
