Module sodiumoxide::crypto::scalarmult::curve25519 [−] [src]

crypto_scalarmult_curve25519 specified in Cryptography in NaCl, Sections 2, 3, and 4. This function is conjectured to be strong. For background see Bernstein, "Curve25519: new Diffie-Hellman speed records," Lecture Notes in Computer Science 3958 (2006), 207–228, http://cr.yp.to/papers.html#curve25519.

Structs

GroupElement	`GroupElement`
Scalar	`Scalar` value (integer in byte representation)

Constants

GROUPELEMENTBYTES	Number of bytes in a `GroupElement`.
SCALARBYTES	Number of bytes in a `Scalar`.

Functions

scalarmult	`scalarmult()` multiplies a group element `p` by an integer `n`. It returns the resulting group element `Ok(q)`. If the the `GroupElement` is all zero, `scalarmult()` returns `Err(())` since the resulting `GroupElement` would be all zero, no matter the `Scalar`.
scalarmult_base	`scalarmult_base()` computes the scalar product of a standard group element and an integer `n`. It returns the resulting group element `q`/
