Encrypts or decrypts a string of text to a string of characters based on a user-specified encryption key. Discussion: The function makes use of bitwise Xor comparisons on the string to be encrypted and a string key provided by the user. This could be useful if you wish to send sensitiv...

The Hill Cipher is a polygraphic substitution cipher that uses matrix algebra to encrypt and decrypt messages. This implementation of the Hill Cipher in Python uses the NumPy library to perform matrix operations. Installation Clone the GitHub repository: git clone https://github.com/Jawabreh0/hil...
Problem 3 [8pt] RSA is an algorithm used by modern computers to encrypt and decrypt messages. The core of RSA is the computation of (pk mod n) where k is confidential (i.e., with k, an attacker can derive the private key). For effic...
CipherPayload middleware for Fiber that use AES Algorithm for encrypt and decrypt payload in request and response body. - owlsome-official/cipherPayload
we pretend that our message to encrypt is a number (although conceptually, we want to encrypt/decrypt some arbitrary series of bytes, we can always put them together and treat them as a big number); we pick two large prime numbers, call them p and q; we multiply p and q together ...
Based on a fixed 56-bit symmetric key, this algorithm creates a single key based on a binary number used to encrypt and decrypt data. Using a block cipher methodology, it uses 64-byte blocks to randomly populate a key. Currently in use by organizations such as the National Security Agency...
The SpSealMessage function and the SpUnsealMessage function do not encrypt and decrypt authentication messages correctly when the message size is not divisible by the expected block size. Resolution Hotfix information Important When you click the "View and request hotfix downloads" link,...
