WebThe RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptosystem -- a suite of cryptographic algorithms that are used for specific security services or purposes -- which enables public key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the internet. WebAn encryption algorithm and all its possible keys, plaintexts and ciphertexts is known as a cryptosystem or cryptographic system. Figure 4 illustrates the process. Figure 4 Encryption and decryption. Cryptography is the general name given to the art and science of keeping messages secret.

WebIn an asymmetric key encryption scheme, anyone can encrypt messages using a public key, but only the holder of the paired private key can decrypt such a message. The security of the system depends on the secrecy of the private key, which must not become known to … WebSymmetric ciphers protect data privacy in most Wi-Fi networks, online banking and e-commerce services, and mobile telephony. Some protocols use asymmetric cryptography to encrypt and authenticate endpoints. They also use it to secure the exchange of symmetric keys to encrypt session data. Those protocols include the following: TLS HTTPS
