LBRY, similar to the Bitcoin protocol, uses predefined curve [secp256k1](https://en.bitcoin.it/wiki/Secp256k1). Here's the simplest possible explanation of the operations: you can add and subtract points and multiply them by an integer. Dividing by an integer is computationally infeasible (otherwise cryptographic signatures won't work). The private key is a 256-bit integer and the public key is a product of a predefined point G ("generator") by that integer: A = G * a. Associativity law allows implementing interesting cryptographic schemes like Diffie-Hellman key exchange (ECDH): two parties with private keys *a* and *b* may exchange their public keys *A* and *B* to compute a shared secret point C: C = A * b = B * a because (G * a) * b == (G * b) * a. Then this point C can be used as an AES encryption key to protect their communication channel.
