What is the definition of a computationally hard problem and how does it relate to the field of cryptography?
A computationally hard problem is a task that is difficult for a computer to solve quickly. In the field of cryptography, computationally hard problems are used to create secure encryption methods. By using algorithms that are difficult for computers to crack, cryptography ensures that sensitive information remains protected from unauthorized access.
The combination of a public key and a private key is known as a?
This is known as RSA encryption. Encryption involving a public and private key combination is known as asynchronous cryptography, as opposed to synchronous cryptography. It is also known as public key cryptography. RSA is an algorithm that may be used (but there are others that can be used), in public key cryptography. (A key pair)
18 What system encryption uses the concept of an asymmetric key?
This is known as public-key cryptography, or asymmetric cryptography which is used to secure electronic communication over a network.
What does hashing mean and how is it used in computer science and cryptography?
Hashing is a process in computer science and cryptography where data is converted into a fixed-size string of characters, known as a hash value. This hash value is unique to the input data and is used for various purposes such as data retrieval, data integrity verification, and password storage. In cryptography, hashing is used to securely store passwords and verify data integrity by comparing hash values.
What does vss mean?
In cryptography, the initials mean: Verifiable secret sharing.It's a protocol that promises that in a system of computers, with a leader that has a secret s and faulty computers -1- If the leader is honest: a- Each honest computer outputs value s_i = sb- at the end of the sharing phase the joint view of the malicious computers is independent in s 2- At the end of the sharing phase the value that the honest computers have determines the output of the honest computers
Where is cryptography used?
Banks use it to protect their clients' details; military and government organisations use it to keep important information secret.

How is cryptography used?
Cryptography is basically the process of hiding information in order to protect the sensitive information, data or message from unknown attacks for any reasons. Cryptography actually consists of two terms encryption and decryption. The process in which message is ciphered or encrypted is known as encryption and the process in which message is deciphered at recipients end is known as decryption. And this whole process is known as cryptography. Public keys and private keys are used in the process of cryptography. Cryptography can be seen as symmetric and asymmetric. In symmetric cryptography same key is used for both encryption and decryption while in asymmetric different keys are used for both encryption and decryption. Today Cryptography is used in various fields like ATM, e-banking, IT security, Maths etc.
What are prime numbers used for in the real world?

What are the types of cryptography?
public key cryptography private key cryptography
What is cryptography and how is it related to computers?
Cryptography is a means of encrypting or obscuring information. It is related to computers mainly by the internet. When data is passed between a client and a server it can be encrypted so that only the desired recipient can decrypt the data and read it, preventing eaves dropping or interception of the data because the eaves dropper will not be able to decrypt the data (not easily anyway). It can also be used when storing data on a computer - thereby preventing anyone decrypting the data and viewing it.

What are different cryptography algorithms?
There are two types of cryptography algorithms: 1) Public key cryptography 2) Secret key cryptography
Why do you use Cryptography?
Cryptography is used to secure sensitive information by encoding it in such a way that unauthorized individuals cannot access or understand it. It helps protect data confidentiality, integrity, and authenticity in digital communications and transactions.
What are the different cryptography algorithms?
There are many different algorithms used in cryptography - RSA, DES and Rabine ciphers are a few that can be used - as well as others that are used to help determine the constants in a system like Euclid's algorithm.
How is prime factorization used in life?
It is used in cryptography (the making and breaking of secret codes).
