As we wrap up our lesson on Symmetric Cryptography, we must address the pros and cons of this encryption method. You'll discuss its greatest pro---speed. But as we know, sometimes being too fast occurs at a cost. Those costs will be discussed when we cover the cons of Symmetric Cryptography, such as Out of Band Key Distribution, lack of authenticity, issues with integrity, and non-repudiation. Knowing what the boundaries are with your encryption resources will enable you to make accurate decisions and advise decision-makers with specific points of fact.
