Is there a modbus TCP with TLS ?

Open schnitzlein opened this issue 2 years ago • 4 comments

Hi,

is there currently some ongoing task to implement the modbus TCP with TLS Support? as documented in modbus org? https://modbus.org/docs/MB-TCP-Security-v21_2018-07-24.pdf

Can I find it some where? would be really cool!

greetings

Maybe I am overseeing something... But it would be cool if I can use libmodbus with TLS support, because we live in 2022 and Encryption is mostly mandatory.

@stephane do you know maybe any project which currently supports modbus TCP + TLS ? Any kind of information would be helpful :) (commercial lib ... secret at ... or any open source lib containing it)

My research results was only that I was able to find a port for Arduino OS seems like they have it for ESP8266, which is quite specific. I am looking more for a generic solution for Linux.

Or ... write it by myself, if there is none solution yet.

No but it could be a good fit for promodbus spin-off before merging it later in libmodbus...

@schnitzlein Before it is ok, maybe you can use some ssl tunnel software to solve this problem. for example: https://github.com/ghostunnel/ghostunnel etc.

@stephane Is there any ongoing/planned work regarding this in the promodbus spin-off as you insinuated earlier? Thanks.
