Encryption
Encryption
Definition: Encryption is a process which is applied to text messages or other important data, and alters it to make it humanly unreadable except by someone who knows how to decrypt it. The complexity of the algorithms used means that a strongly encrypted message might require thousands of years of processing by very fast computers to break the encryption. The most popular use of encryption is for securing web servers that are accessed by the https protocol not http so that data such as credit cards can be sent safely over the internet.
Symmetric Encryptiont
Where a single secret key is used for both encryption and decryption.
Asymmetric Encryption
Where a pair of keys is used, one for encryption and the other for decryption.
