Hill Cipher DecryptionTo decrypt the message, we turn the ciphertext back into a plain text, then simply multiply by the inverse matrix of the key matrix as "IFKVIVVMI" in letters. The inverse of the matrix used in the encryption is,...
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/hill-cipher Install NumPy: pip install numpy ##Usage To encrypt a message using the Hill Cipher, run hill-...

Because the Hill cipher is linear, we only need to find 2 bigram correspondences to determine the key matrix. For example, if we knew that 'th' was encrypted to 'gk' and 'er' was encrypted to 'bd', we could solve a set of simultaneous equations and find the encryption key matrix. ...
2) Playfair Cipher Playfair cipher (aka Playfair square) is a cryptography technique used for manual encryption, it was introduced by Charles Wheatstone in 1854 but it was popularized by Lord Playfair hence his name used. The Playfair cipher was used in world war I by the British ar...
Akbal, Barua, Dogan, Tuncer, and Acharya (2022) introduced a data encryption standard cipher model - DesPatNet25 which utilized a novel hand-modeled automated system and was evaluated on a public construction site monitoring (CSM) sound dataset. An accurate fire learning model was proposed by ...
