This program is a proof-of-concept demonstrating an encrypted message exchange between two entities using Elliptic Curve Cryptography. ECC public/private key crypto is used in conjunction with the Diffie-Hellman primitive to allow both sides to independently generate a one-time use shared secret key that is used for encryption of data using a symmetric key algorithm.

2. sslcrypto can use OpenSSL in case it's available in your system for speedup, but pure-Python code is also available and is heavily optimized. N.B. There are alternatives like coincurve which are faster in some cases (e.g. when using secp256k1). They don't include ECIES implementation and some useful ECDSA features and are specialized on a single curve. If that's enough for you and libsecp256k1 bindings are available for all OSes you need to support, use those libraries

By voting up you can indicate which examples are most useful and appropriate As mentioned above, ECIES is a common way to do it but it is based on symmetric keys and it forces both sides to agree on the key while the idea with PKI encryption is that one can publish his public key so anyone can send data that can be read only by the publisher.

For one thing, ECIES basically does an ECDH exchange with the receiver's public key and a random ephemeral private key to derive a shared secret, which is then used as the key for AES-encrypting the message. The message is sent over to the recipient along with the AES parameters (IV, MAC) and the ephemeral public key. The recipient can use that public key along with their private key in ECDH, get the same shared secret, and do another round of AES with the given parameters to.
