This technique allows data to be accessible only to people who have the authority. In a growing world, the need for information security is increasing, making the use of secret codes a relevant solution to protect data from irresponsible parties.
Since ancient times, secret codes have been used in secret communications, and until now the fabrication techniques have continued to adapt to the development of modern technology. Various new methods and strategies have been created to improve the effectiveness and complexity of secret codes. The following guidelines will provide steps that you can follow to create a secret code that suits your security needs.
