WebApr 10, 2024 · Security: RSA algorithm is considered to be very secure and is widely used for secure data transmission. Public-key cryptography: RSA algorithm is a public-key cryptography algorithm, which means that it uses two different keys for encryption and decryption. The public key is used to encrypt the data, while the private key is used to … WebIn RSA composite number-based, two-key cryptologic systems, there are public keys and private keys. Trying to crack the codes (the encryption procedures) requires use of advanced number theories that allow, for instance, an unauthorized user to determine the product of the prime numbers used to start the encryption process.
