TLS encryption wrapper

The tlswrapper is an TLS encryption wrapper between remote client and local program prog.

Internet <--> tcpserver/inetd/systemd.socket/... <--> tlswrapper <--> prog

Separate process for every connection

The tlswrapper is executed from systemd.socket/inetd/tcpserver/... which runs separate instance of tlswrapper for each TLS connection. It ensures that a vulnerability in the code (e.g. bug in the TLS library) can't be used to compromise the memory of another connection.

Separate process for network connection and for secret-key operation

To protect against secret-information leaks to the network connection (such Heartbleed) tlswrapper runs two independent processes for every TLS connection. One process holds secret-keys and runs secret-keys operations and second talks to the network. Processes communicate with each other through unix pipes.

Privilege separation, filesystem isolation, limits

The tlswrapper processes run under dedicated non-zero uid to prohibit kill, ptrace, etc. Is chrooted into an empty, unwritable directory to prohibit filesystem access. Sets ulimits to prohibit new files, sockets, etc. Sets ulimits to prohibit forks.

TLS library

The tlswrapper is using BearSSL library which implements only secure versions of TLS protocol (TLS1.0 - TLS1.2). And implements safe and constant-time algorithms.
