Public-Key Cryptography: A Secure Digital Handshake
In recent years, public-key cryptography has become a crucial aspect of online security. This digital handshake enables secure communication and data transmission over the internet. In this article, we'll explore the basics of public-key cryptography, including RSA (Rivest-Shamir-Adleman) and ECC (Elliptic Curve Cryptography).
RSA is an older method that has been widely used for decades, while ECC offers similar security with smaller keys, making it more suitable for mobile devices and IoT applications. Both methods involve generating public and private keys to encrypt and decrypt data.
To ensure secure key generation, randomness plays a critical role. It's essential to use reliable random number generators like crypto/rand to avoid weak randomness. Additionally, regular key rotation and standard formats like PEM for storing and sending keys are vital best practices.
In conclusion, public-key cryptography is a powerful tool for securing online transactions and communication. By understanding the basics of RSA and ECC, developers can create robust applications that prioritize security and trust.
