Basic example to understand how cryptography works is given below:
Which of the following choices true about cryptography?
A. Algorithm is not the secret; key is the secret.
B. Public-key cryptography, also known as asymmetric cryptography, public key is for decrypt, private key is for encrypt.
C. Secure Sockets Layer (SSL) use the asymmetric encryption both (public/private key pair) to deliver the shared session key and to achieve a communication way.
D. Symmetric-key algorithms are a class of algorithms for cryptography that use the different cryptographic keys for both encryption of plaintext and decryption of ciphertext.
