Description : 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.
I'm using this software and I'm going to maintain using https://salsa.debian.org/
Currently is the Debian package maintained here https://salsa.debian.org/janmojzis/tlswrapper,
I would need to create a https://salsa.debian.org/debian/tlswrapper repository before uploading.
I need sponsor.
