Cryptography, the study, and practice of secure communication through unique methods and techniques prevents third parties or organizations from accessing sensitive information. In modern cryptography, concepts like confidentiality, data integrity, authentication, etc. play a crucial role. The Hill Cipher … See more Hill Cipher, in the pretext of classical cryptography, follows a polygraphic substitution cipher, which means there is uniform substitution across multiple levels of blocks. This polygraphic substitution cipher makes it … See more As an example of the Hill Cipher technique, let’s encrypt the text, ‘ACT’, and, later, decrypt the resulting ciphertext. This will help us understand … See more When dealing with 2×2 matrices, Hill Cipher is easily solvable. But when it comes to modern cryptography solutions that have 256 combinations of numbers, Hill Ciphers can be fairly weak.
