Cryptography - The study of techniques related to all aspects of data security. The word "cryptography" is derived from the ancient Greek words "kryptos" (hidden) and "graphia" (writing). Some aspects of data security: Confidentiality - Keeping data secret. Data Integrity - Ensuring data has...
Steganography is the art of hiding secret messages in plain sight. Learn about steganography types, techniques, applications, examples, and more.
While the goal of cryptanalysis is to uncover flaws in or otherwise circumvent cryptographic algorithms, cryptographers use the research of cryptanalysts to strengthen, replace, or otherwise advance subpar methods. Cryptography, which focuses on creating and enhancing encryption cyphers and other techniqu...
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 ...
What is if __name__ == "__main__"? By: Rajesh P.S.In Python, the __name__ attribute is a special built-in variable that holds the name of the current module or script. When the Python interpreter runs a script or module, it assigns the value __main__ to the __name__ ...
Incryptography,codeis the substitution of one word or phrase by another word, number or symbol for the purpose of concealing the original word or phrase. This could be used to hide someone's true intention from prying eyes and ears or to designate a military mission such as in World War ...
Absolute value is a versatile mathematical concept. Its uses range from basic numerical operations like solving equations or calculating distances, to more advanced topics like cryptography, where it helps computers process encoded messages. In computing, absolute value is often used when dealing with ...
This is the foundation of attempts at infiltration in any hacker security situation. Cryptography & Reverse Engineering: Encryption or decryption of data mostly involves cryptography. For a skilled hacker, it is important that he or she can crack a code to get the information, or ensure the ...
There are various hash options in the SHA-2 family. ThehashlibSHA-256 constructor generates a more secure version in that family with a 256-bit hash value. Programmers often use SHA-256 for cryptography, like digital signatures or message authentication codes. The code below demonstrates how to...
Encryption and Cryptography Techniques:Encryption is crucial for protecting sensitive data both when it's stored (at rest) and when it's being transmitted (in transit). Using proven cryptographic libraries and protocols ensures data is protected with strong, up-to-date algorithms, preventing unauthori...
