The need to break ciphers drived the development of computers. WebJun 29, 2024 · Encryption is a technique of using a cipher (algorithm) to convert standard information to a scrambled version. In that case, the attacker won’t make sense of the details even if it gets exposed. There are various types of encryptions based on the use case. So it’s important to use a quality cipher for cloud data encryption.
