The TLS Pool is a central daemon running on your server system, or perhaps under your personal desktop session. It manages your TLS connections from one central place.

Programs that wish to employ TLS basically hand over a normal connection to the TLS Pool, and receive a TLS-protected connection back in exchange for it. Then they can continue to communicate without further awareness of the TLS-wrapping that has taken place.

This approach can be done at the beginning of a protocol, which is the original way TLS was used; or it can be used by any protocol implementation at the point it is processing a STARTTLS switch.

The TLS Pool is a pure TLS implementation, so it can communicate with both a TLS Pool on the remote end, or any other TLS implementation. One thing that sets TLS Pool apart however, is its wide range of implemented features, and its consistent, central control to determine which of these features are welcomed and which are not.
