Library for elliptic curves cryptography

Public key cryptography library for Ruby providing the X25519 Diffie-Hellman function

Updated! (Dec2-2019) This is a C-language software library that provides optimized implementations of the Diffie-Hellman functions known as X25519 and X448 (RFC-7748) for 64-bit architectures.
