In the following sections, we’ll encrypt and decrypt a string using C#, first with symmetric encryption and then with asymmetric encryption. We’ll use a string as the data in our examples to ...

Encryption-decryption is one of those techniques which are quite popular. But, the complexity which is involved in this technique doesn’t allow its users to apply it in a simpler way.

A novel strategy for optical encryption/decryption of information is based on compounds with carefully modulated luminescent properties that change in response to external stimuli.
