looking for a solution to send emails in SSL

[Gilles]

Hello, almost all internet service providers are or switch to SSL/TLS… (Finally in France for the rest of the world, I’m not sure)
Only Gmail via sendgrid for the moment remains unencrypted, but you cannot send attachments with this service!

I work with Arduino Mega and w5500 Ethernet shields.

So my question is this impossibility of using SSL/TLS does it come from the hardware (shield or Arduino?) or from the libraries?

I must admit that I don’t understand the subject at all…

In my research I came across this article:

https://github.com/OPEnSLab-OSU/SSLClient

Would this be a solution?
Or other things?
Does anyone have a solution?
THANKS

no one has any idea on the subject? THANKS

Hi Gilles,
the SSLClient is already implemented in the library, but the memory is insufficient for devices like Arduino Mega, It works well with STM32.

STM32: ethernet w5500 standard (HTTP) e SSL (HTTPS) – 5

Here the keyword to enable It on EMailSender.

Hello, thank you for this sad response!
I still wanted to try on an Arduino Mega and W5500 shield in SSL, so I uncommented the line you told me in EMailSenderKey.h#L81. Then I tried to compile my sketch of course I had to install the SSLClient library but this one does a #include<vector> .
So I also installed the vector library but there I always have this:
C:\Users\PC bureau Gilles\Documents\Arduino\libraries\SSLClient\src/SSLClientParameters.h:31:10: fatal error: vector: No such file or directory
#include <vector>

Did I miss something?
THANKS
PS: suddenly there is no other way to send emails with an Arduino mega and w5500 in SSL?

Hello, is there a way to send emails via ssl from Arduinos mega by adding an stm32 (for 5 Arduinos) or something else, knowing that some emails send attachments from the micro SD of the w5000 shields?
THANKS

You can think of a solution that uses a UDP packet to send message to a central unit It is used to send email.
The only thing you must check is if all the devices are on the same network.

Hello, do you have an example somewhere to inspire this (using a UDP packet to send a message to a central processing unit)?
THANKS

Hi,
you can find more information on this article.
