Rsa — And Public Key Cryptography Cryptography

: RSA is unique because either key can be used for encryption with the other performing the decryption, which allows it to be used for both confidentiality and authentication.

: Its security relies on the "factoring problem" —the extreme computational difficulty of factoring a very large number back into its original two large prime numbers. RSA and Public Key Cryptography Cryptography

According to experts from TechTarget and RSA Security , RSA is primarily used for: : RSA is unique because either key can

is calculated using the Extended Euclidean Algorithm such that . The private key is the pair : Encryption : is ciphertext and is plaintext). Decryption : The private key is the pair : Encryption

: RSA uses two distinct keys: a public key for encryption (known to everyone) and a private key for decryption (kept secret by the owner).

: Since RSA is computationally expensive, it is often used to securely exchange a symmetric key , which then handles the bulk encryption of larger data sets. How the RSA Algorithm Works Key Generation : Select two large, distinct prime numbers ( ) and calculate their product ( ), which serves as the modulus for both keys. Public Key Creation : An integer

: Establishing secure connections between web servers and browsers via SSL/TLS protocols .
