Precompiled static binary may be found in
http://busybox.net/downloads/binaries/

Build instructions:

* Unpack wolfssl-3.9.8.tar.gz from https://github.com/wolfSSL/wolfssl/releases
  to a wolfssl-3.9.8 subdirectory here.
* Create configure:
	(cd wolfssl-* && ./autogen.sh)
* Build it: see
	(cd wolfssl-* && ../00cfg-wolfssl-3.9.8)
* Run
	./ssl_helper.sh
  to compile and link the helper

Usage: "ssl_helper -d FILE_DESCRIPTOR" where FILE_DESCRIPTOR is open to the peer.

In bash, you can do it this way:
$ ssl_helper -d3 3<>/dev/tcp/HOST/PORT

Stdin will be SSL-encrypted and sent to FILE_DESCRIPTOR.
Data from FILE_DESCRIPTOR will be decrypted and sent to stdout.
