WebJun 11, 2024 · Elliptic curve cryptography (ECC in short) brings asymmetric encryption with smaller keys. In other words, you can encrypt your data faster and with an equivalent level of security, using comparatively smaller encryption keys. As you may know, public-key cryptography works with algorithms that you can easily process in one direction. WebCrypto.PublicKey package Unlike keys meant for symmetric cipher algorithms (typically just random bit strings), keys for public key algorithms have very specific properties. This module collects all methods to generate, validate, store and retrieve public keys. API principles Asymmetric keys are represented by Python objects.
