In large environments, your encryption keys may be held by a third-party to ensure that the encrypted data can always be recovered. In this video, you’ll learn about key escrow and some of the business cases where key escrow should be used.
Hashing functions can provide us with some interesting ways of validating data. In this video, you’ll learn the fundamentals of hashing and I’ll demonstrate how you can validate a downloaded file by calculating a hash.
Our encryption technologies not only provide a secure channel of communication, but they can also prove that the data we’re receiving has not been changed between endpoints. In this video, you’ll learn about non-repudiation and how digital signatures can ensure the integrity and authenticity of our data.

To provide a secure channel, both sides of the conversation need to share the keys that will be used during the session. In this video, you’ll learn about session keys and the different methods used to provide a secure exchange of session keys.
Asymmetric encryption uses two different keys to provide a secure channel. In this video, you’ll learn how public keys and private keys can be used to encrypt data, create digital signatures, and create a secure symmetric key.
