RSA Algorithm

The RSA algorithm is a widely used public-key cryptosystem for secure data transmission, developed by Rivest, Shamir, and Adleman in 1977. It enables encryption and digital signatures by leveraging the mathematical difficulty of factoring large prime numbers, ensuring confidentiality and authentication in digital communications.

Also known as: RSA, RSA Cryptosystem, Rivest-Shamir-Adleman, Public-Key Cryptography, Asymmetric Encryption

Why learn RSA Algorithm?

Developers should learn RSA for implementing secure communication in applications like HTTPS, email encryption (e.g., PGP), and digital certificates, as it's foundational for modern cybersecurity. It's essential when building systems requiring data privacy, such as online banking, e-commerce, or any scenario involving sensitive information exchange over untrusted networks.
