  What is Cryptography? Cryptography is protecting the confidentiality and integrity of the information without being vulnerable to attackers or threats. It is an encryption technique when ensures the data is only visible to the sender and recipient and no middle man can steal the data and snoop for information. There are three most common types of cryptographic techniques in general. They are – Symmetric key cryptography   – Here the sender and receiver share a similar key and it can be used for both encryption and decryption. Hash functions  – There is no key used, rather a hash value is used to encrypt text, contents, and passwords. Public key cryptography   – In this two different keys such as a public key for encryption and a private key for decryption is used. Only the private key is kept as secret. Encryption Tools and Techniques: There are few tools available for encryption technique. They include – Triple DES – Replaces Data encryption standard(DES) algorit...

  HackerRank Tuples Solution in Python Task Given an integer,n, and n  space-separated integers as input, create a tuple, t, of those n integers. Then compute and print the result of hash(t). Note:   hash()  is one of the functions in the  __builtins__  module, so it need not be imported. Input Format The first line contains an integer,n, denoting the number of elements in the tuple. The second line contains n space-separated integers describing the elements in tuple t . Output Format Print the result of  hash(t) . Sample Input 0 2 1 2 Sample OUTPUT- 3713081631934410656 n = int(input()) int_list = [int(i) for i in input().split()] int_tuple = tuple(int_list) print(hash(int_tuple))

  What is a computer port? | Ports in networking- What is a port? A port is a virtual point where network connections start and end. Ports are software-based and managed by a computer's operating system . Each port is associated with a specific process or service. Ports allow computers to easily differentiate between different kinds of traffic: emails go to a different port than webpages, for instance, even though both reach a computer over the same Internet connection. What is a port number? Ports are standardized across all network-connected devices, with each port assigned a number . Most ports are reserved for certain protocols — for example, all  Hypertext Transfer Protocol (HTTP) messages go to port 80. While IP addresses enable messages to go to and from specific devices, port numbers allow targeting of specific services or applications within those devices. How do ports make network connections more efficient? Vastly different types of data flo...
