Some argue that purchasing certificates for securing websites by SSL/TLS and securing software by code signing is a costly venture for small businesses. [41] However, the emergence of free alternatives, such as Let's Encrypt, has changed this.
For example, a software publisher can create a signature key pair and include the public key in software installed on computers. Later, the publisher can distribute an update to the software signed using the private key, and any computer receiving an update can confirm it is genuine by verifying the signature using the public key.

A user Alice can doubly encrypt a message using another user's (Bob) public key and his (Bob's) identity.. This means that the user (Bob) cannot decrypt it without a currently valid certificate and also that the certificate authority cannot decrypt the message as they don't have the user's private key (i.e., there is no implicit escrow as with ID-based cryptography, as the double encryption ...
