Illustrate the Encryption and Decryption methods
One of the best method of ensuring security is to change the form of communication. Let the messages be encoded in such a pattern that it becomes almost impossible to decode for others while the actual user should be able to decode with the use of a simple certificate or key. There are three well known implementations of the encryption/decryption methods:
Even though there are a number of other solutions available, the encryption/ decryption methods have remained most popular and economical in comparison with the other methods. Details about each of the security solution have been discussed in detail in the following paragraphs.
