Properties XOR is an associative operation i.e. re-arranging the parenthesis in an expression having two or more same associative operators in a row Read More

SHA stands for Secure Hash Algorithm. It consists of five hash functions designed by the National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST). The five algorithms are SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. SHA-1 is the most commonly used of the SHA series. Hash algorithms are called secure when It is impossible to find a message that corresponds to a given message digest. It is impossible to find two different messages that produce the same message digest. If a message is changed even Read More

In a symmetric cipher, both parties must use the same key for encryption and decryption. This means that the encryption key must be shared between the two parties before any messages can be decrypted. Symmetric systems are also known as shared secret systems or private key systems. Symmetric ciphers are significantly faster than asymmetric ciphers, but the requirements for key exchange make them difficult to use. In an asymmetric cipher, the encryption key and the decryption keys are separate. In an asymmetric system, each person has two keys. One key, Read More

In 1748, Montesquieu wrote in De L’Esprit des Lois “Useless laws weaken the necessary laws.” Today, we have so many useless laws that the government and police do not have the resources to enforce the necessary laws. The accepted solution, of course, is to Read More
