Though we may not be aware of how it is being employed to things we do not control, we can use it consciously to protect ourselves. Protecting data from unauthorized viewing while in transit to its destination. This degree of access is rarely an ideal situation. Encryption is one tool that can prevent even the super user from being able to read the files although it should not be considered the sole tool for data security. Even though administrators cannot read the document, they still have the ability to delete it, so caution must be used in protecting your files.
Security is a process.
Although these components may seem obscured in many implementations, they all should be considered when evaluating the encryption system. The Plaintext - Plaintext is the information, data or message you wish to encrypt with the algorithm. The Algorithm - The encryption algorithm is the mathematical function that performs the instructions to encrypt and decrypt the data with use of the key. The Key - The encryption key is the component that binds everything together. When used in tandem with the algorithm it provides a unique method for the data to be encrypted or decrypted.
