2 | EFI TLS Protocols as defined in UEFI 2.5.\r | |
3 | \r | |
4 | The EFI TLS Service Binding Protocol is used to locate EFI TLS Protocol drivers\r | |
5 | to create and destroy child of the driver to communicate with other host using\r | |
6 | TLS protocol.\r | |
7 | The EFI TLS Protocol provides the ability to manage TLS session.\r | |
