Application Of Rectangular Matrices: Affine Cipher Using Asymmetric Keys

Cauchy: Jurnal Matematika Murni dan Aplikasi, 2019
In cryptography, we know the symmetric key algorithms and asymmetric key algorithms. We know that the asymmetric key algorithm is more secure than the symmetric key algorithm. Affine Cipher uses a symmetric key algorithm.
