Digital Signatures in Python: ECDSA, EdDSA, RSA, DSA

Digital signatures are a crucial component of modern cryptography, ensuring data integrity and authentication. In this video, I demonstrate how to implement digital signature algorithms in Python using LightDSA, a versatile library that supports Elliptic Curve Digital Signature Algorithm (ECDSA), Edwards-Curve Digital Signature Algorithm (EdDSA), RSA, and DSA. With just a few lines of code, you can securely sign and verify messages. LightDSA provides extensive support for different elliptic curve forms, including Weierstrass, Koblitz, and Edwards, along with hundreds of pre-defined curves such as secp256k1 (bitcoin's curve), ed25519. This makes it a powerful choice for cryptographic applications, offering flexibility and ease of use. Whether you're working with elliptic curve cryptography or traditional RSA and DSA signatures, this video walks you through the essential steps to get started.
