15.1 What is key recovery?

A certificate and private key is used to encrypt and decrypt information; for example, emails and documents.

If you lose the private key, you cannot access the encrypted information, unless you can recover the private key; to do this, the key must have been securely stored. Secure storage of the private key is called key escrow.

Key recovery is the process of retrieving the private key from escrow, along with the certificate, and providing it to the person that needs to access the encrypted information.
