Protecting data By encryption . How do we transmit information and data, especially over the internet, in a way that is secure and unreadable by anyone but the sender and recipient?. Encryption is simply the process of transforming information, such as plain text or numbers, using an algorithm. Only those with the algorithm can decipher the encrypted information, and even a relatively simple encryption technique can be difficult to decode without the key. . Rainbows (a.k.a. Spectrums).

Yes, Encryption is safe. The amount of time, energy and cost to crack most modern cryptographic technologies makes the act of attempting to decrypt encrypted code an expensive task that is, virtually speaking, inevitable. Although encryption does have vulnerabilities that rest largely outside of the power of the technology. Meaning if you give someone a USB with the key or tell them it.. Diffie. -Hellman. The .
