Discuss the private key encryption technique and its shortcomings
To encode a message, the sender provides the encryption algorithm with the key, which produces the ciphertext message. This is transmitted to the receiver's location, where it is decoded using the same key to produce a cleartext message. Because the same key is used for coding and decoding, control over the key becomes an important security issue. The more individuals that need to exchange encrypted data, the greater the chance that the key will become known to an intruder who could intercept a message and read it, change it, delay it, or destroy it.
