So I got bored and wrote the thing today. A customary disclaimer

1) The code is public domain.

2) The code is fugly so I don't claim the authorship. It's bound to
break in next version of openssl anyway.

3) It was tested on Debian GNU/Linux amd64 only, although I don't see
why it should not work elsewhere.

4) Nor the code nor the library are supported by Debian project or the
upstream. I won't support it either.

5) There is no guaranties. If it breaks anything it's your problem, not


apt install gcc-7 libssl-dev
tar xf tls10.tar.gz
# might add -funroll-oops and -fvomit-frame-pointer here
gcc -fPIC -shared -O4 -pipe -g -s -o tls10.so tls10.c
strip tls10.so

LD_PRELOAD=$PWD/tls10.so <ur_ssl_client_here>


Attachment: tls10.tar.gz
Description: application/gzip
