What are the difference between cryptography cryptanalysis?
The word cryptography means hidden writing, and it refers to the practice of using encryption to conceal text.. And cryptanalysis studies encryption and encrypted messages, hoping to find the hidden meanings.
What does cryptology mean?
cryptology is the science of making codes.
What is the difference between private key and secret key as applied to coding theory and cryptology?
"Private key" in the context of cryptography refers to the the key generated for an asymmetric encryption algorithm which is retained by the owner while the companion "public key" is published for others to utilize for secure communications or authentication. The "private key" is not shared with anyone. A "secret key" in the context of cryptography refers to the single key generated for use in a symmetric encryption algorithm which is only shared between those between whom secure communication is desired. It is kept secret from all others. The secret key must be transmitted to or shared with all parties by a method outside the communications link it is intended to secure.
What do cryptographer do?
Cryptography(or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively)[1]is the practice and study of techniques for secure communication in the presence of third parties (called adversaries).[2]More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries[3]and which are related to various aspects in information security such as data confidentiality, data integrity,authentication, and non-repudiation.[4]Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.https://en.wikipedia.org/wiki/Cryptography
What are the different types of cryptography?
There are 2 types of cryptography such as: 1- Symmetric-key or Secret key Cryptography 2- Asymmetric-key or Public key Cryptography
