Struct p384::AffinePoint

source · [−]

pub struct AffinePoint { /* private fields */ }

Available on crate feature broken-arithmetic-do-not-use only.

Expand description

NIST P-384 (secp384r1) curve point expressed in affine coordinates.

`serde` support

When the serde feature of this crate is enabled, the Serialize and Deserialize traits are impl’d for this type.

The serialization uses the SEC1 Elliptic-Curve-Point-to-Octet-String encoding, serialized as binary.

When serialized with a text-based format, the SEC1 representation is subsequently hex encoded.

Implementations
