-In cryptography, Curve25519 is an elliptic curve offering 128 bits of security and designed for use with the elliptic
-curve Diffie–Hellman (ECDH) key agreement scheme. It is one of the fastest ECC curves and is not covered by any known
-patents. The reference implementation is public domain software. The original Curve25519 paper defined it
-as a Diffie–Hellman (DH) function.
