WebRSA algorithm uses the following procedure to generate public and private keys: Select two large prime numbers, p and q. Multiply these numbers to find n = p x q, where n is called the modulus for encryption and decryption. Choose a number e less than n, such that n is relatively prime to (p - 1) x (q -1). It means that e and (p - 1) x (q - 1 ... WebNov 30, 2024 · Public Key Cryptography is a type of cryptography that uses pairs of keys. In this system, one key is public, meaning that it can be known by anyone. The second key is the private key, and it is known only by the owner. In this system, a person uses the public key to encrypt a message. That message is then decrypted by the private key.
