One of the fundamental examples of cryptography is the Caesar cipher, a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet. Here's a simple Python implementation to showcase the concept: def caesar_cipher(text, shift): result ...
Steganography, unlike cryptography, does not involve the scrambling of data, which involves a key. This form of hiding information can be cleverly executed in several ways. Now that we know what steganography is let’s understand its purpose. As is quite apparent, the purpose is primarily to ...
Today, we have learned what decryption is, how to decrypt a file, as well as its applications. Both encryption and decryption are the two key functionalities in cryptography, which is used to secure and protect data during communication. Any user receiving an essential encrypted document from som...
The most popular language for implementing cryptography is C++ since it provides functions for complex arithmetic operations like exponentiation (used in RSA), working with large integers (used in Diffie–Hellman Key Exchange), hash functions (SHA256 and SHA512), etc., all while maintaining good ...
In Python, None is a special keyword that represents the absence of a value. It is used to signify that a variable or object does not have a value assigned to it. In other words, it is a way to represent "nothing" or "null" in Python. Use of None When you create a variable ...
Generic error messages should be displayed to users, while detailed technical information is logged securely for debugging purposes, preventing attackers from gaining valuable insights into the system. Encryption and Cryptography Techniques: Encryption is crucial for protecting sensitive data both when it's...
Learn what a blockchain is, and how cryptography can be used by businesses. A blockchain is a set of blocks containing data, that have been chained together, one on top of another.
Python API is provided to access all functionalities. PyMol was originally written by Warran Delano in Python in the early 2000's and released as an open-source project. Unfortunately, Warren passed away in 2009. PyMol is maintained now by Schrodinger with 2 editions: free academic edition and...
This section describes what is cryptography - The study of techniques related to all aspects of data security.
This section describes what is CGI::Cookie, which is a sub class of the CGI.pm Perl module, which help you to create HTTP cookies and manage them in HTTP headers of request and response messages.
