Advantages of Cryptography
* Some techniques such as hashing, are known to preserve the integrity of the message.
* It is used to guard highly confidential information and data.
* It offers protection from users not intended to have access to a message.
* Digital signatures provide non-repudiation against disputes that arise in situations where the sender denies passing of the message.
Disadvantages of Cryptography
* It can prove to be dangerous if the system design is not properly managed.
* Sometimes, a strongly encrypted message cannot be read by even the intended or legitimate user. This has been known to happen in many cases.
* The whole concept of cryptography relies on the complexity of mathematical algorithms. What if someone breaks through the complex algorithms, the entire * cryptosystem would be vulnerable to threats.
