Detailed explanation-1: -These mechanisms are known as specific security mechanisms. Encipherment − This is the procedure of using numerical algorithms to change data into a form that is not freely intelligible. The transformation and subsequent recovery of the information based on an algorithm and zero or higher encryption keys.
Detailed explanation-2: -Encryption is a process that renders data unreadable to anyone except those who have the appropriate password or key. By encrypting sensitive files (by using file passwords, for example), you can protect them from being read or used by those who are not entitled to do either.
Detailed explanation-3: -Cryptography ensures the integrity of data using hashing algorithms and message digests. By providing codes and digital keys to ensure that what is received is genuine and from the intended sender, the receiver is assured that the data received has not been tampered with during transmission.
