Program executes scalar multiplication on a provided point, G (input) and a provided 256-bit randomly generated private-key, d (input). The program defaults to the secp256k1 base point. Inputs should be in big-endian hexidecimal. Program has only been tested on a few points using a variety of private-keys. User generates the user's public-key by Q=dG and provides it to another user. The other user provides their public-key (q) which generates the shared-key, S=dq by running the algorithm again. The shared-key (S) is used to encrypt and decrypt messages shared between the two users using an algorithm such as AES (Advanced_Encryption_Standard). This program was not designed for high speed but executes rather quickly none the less. The program does not run a check to verify the input point is on the elliptic curve (y^2=Y=x^3+7).
