RSA

RSA (Rivest-Shamir-Adleman) is a widely used cryptographic algorithm that secures data transmission through public-key encryption, commonly used in blockchain and digital security.

How RSA Works

RSA relies on a pair of keys, one public, one private. Data encrypted with the public key can only be decrypted with the matching private key, making it ideal for secure communications. The strength of RSA comes from the mathematical difficulty of factoring large prime numbers, which helps ensure security. While more common in traditional finance and internet security, RSA also plays a role in blockchain for identity verification and secure messaging.

Why RSA Matters

RSA laid the foundation for modern encryption. Even as blockchain ecosystems explore newer cryptographic systems, RSA remains a critical reference point in public-key infrastructure and continues to secure many aspects of digital communication and blockchain integration.
