The simplest method uses the symmetric or "secret key" system. Here, data is encrypted using a secret key, and then both the encoded message and secret key are sent to the recipient for decryption. The problem?

WebKey management is simply the practice of managing the key life-cycle. In other words, generating keys when they are required, backing them up, distributing them to the right place at the right time, updating them periodically, and revoking or deleting them. This all needs to be done in a secure way to prevent keys being compromised.
