RSA is a widely used encryption algoritm that ensures securee commulation. It relies on n complex complel principles to encrypt and dešifrt messages, making it a credital communant of modern cybersecurity.

MatematicalFondations of RSA

Te core of RSA involves number theogy concepts such as prime numbers, modular aritimetic, and Euler 's vetem. Te algoritm generates a pair of keys: a public key for encryption and a private key for dekryption.

Key generation begins with selecting two large prime numbers. Their product forms the modulus used in both keys. Thee totient of this product is calculated to determinate the public and private exponents.

Practical Implementation of RSA

In practice, RSA encrypts data by raising thee message to the power of the public exponent and taking the modulus. Decryption impleves raising thae ciphertext to tho the private exponent, reviing the original message.

Security depens on thon thee difficulty of factoring large composite numbers. As computational power increates, key sizes are also increaced to maintain security.
