CRYPTOGRAPHY AND ENCRYPTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In cryptography, “secret algorithm” refers to an algorithm designed in a way that prevents the examination of its inner workings.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Definition(s): A cryptographic algorithm that uses secret keying material that is shared between authorized parties. A cryptographic algorithm that employs the same secret key for an operation and its complement (e.g., encryption and decryption).

Detailed explanation-2: -Hash Functions A hash function is a one-way cryptographic algorithm. The use of a one-way cryptographic algorithm means that the ciphertext cannot be decrypted to reveal the original plaintext. The algorithm is made of two parts. The first element is the original content and is called the message.

Detailed explanation-3: -Steganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination.

Detailed explanation-4: -Symmetric cryptography refers to the practice of the same key being used for both encryption and decryption.
