A sample Python code to generate public / private key pair and encrypt and decrypt a message using ECIES is: Run the above code example: https://repl.it/@nakov/ECIES-in-Python. The above code is pretty simple: just generate ECC public + private key pair using ecies.utils.generate_eth_key () and call the ecies.encrypt (pubKey, msg) and decrypt. ECIES. ECIES.py contains the sage based implementation and ECIES5.py contains pure python based implementation.

A python-based application to aid in summarizing long documents to save time. The contents can be encrypted/decrypted using ECIES algorithm to ensure security 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 // get ECIES cipher objects: Cipher acipher = Cipher. getInstance( ECIES ); // generate derivation and encoding vectors: byte [] d = new byte [] { 1, 2, 3, 4, 5, 6, 7, 8}; byte [] e = new byte [] { 8, 7, 6, 5, 4, 3, 2, 1}; IESParameterSpec param = new IESParameterSpec (d, e, 256); // encrypt the plaintext using the public key: acipher. init(Cipher

Elliptic curve scalar multiplication is the operation of successively adding a point along an elliptic curve to itself repeatedly. It is used in elliptic curve cryptography (ECC) as a means of producing a one-way function.The literature presents this operation as scalar multiplication, as written in Hessian form of an elliptic curve.A widespread name for this operation is also elliptic curve.
