Understanding RSA Encryption
RSA is one of the foundational public-key cryptography algorithms, used to secure everything from web traffic to email encryption and digital signatures. It works by generating two mathematically linked keys -- a public key that anyone can use to encrypt data or verify signatures, and a private key that only the owner uses to decrypt data or create signatures. The security relies on the mathematical difficulty of factoring the product of two very large prime numbers.
