If you lose your encryption key, you’ll lose access to all of your data. In this video, you’ll learn about key recovery techniques and how some certificate authorities can manage your encryption keys.
If you have a large number of devices using a public key infrastructure, you’ll need a way to manage all of the keys in the infrastructure. In this video, you’ll learn about public key infrastructures and the key management lifecycle.
