Encryption is a technique that uses math to transform information in a way that makes it unreadable to anyone except those with special knowledge, usually referred to as a “key ”. There are many applications of encryption technologies, but some of the most important uses help to protect the security and privacy of files on your computer, information passing over the Internet, or left sitting in a file on someone else’s computer. If encryption is used properly, the information should only be readable by you and people that receive the key from you. Encryption provides a very strong technical protection against many kinds of threats — and this protection is often easy to obtain. Many public cloud storage offer different encryption technologies to protect user privacy normally is AES-128 bits or AES (Advance Encryption Standard ) – 256 bits encryption algorithm, but it is a defenseless encryption from 10 years ago. In near future, the current encryption algorithm is easy to be cracked by cloud computing and quantum computing. Now, Flipscloud quantum level encryption is capable to defense quantum computing attacks to ensure your privacy and data safe in public space.
