Hello,
I have a project that needs to secure a file exchange over Ethernet and USB (4G modem).
It seems that NetX does not manage in standard sFTP and SSL.
One acceptable way could be to encrypt the file on server side, get it by standard ftp and decrypt it once downloaded in S7 (on a SD card).
I'm a very beginner in crypto. I know that S7 embed specific peripheral for this, but i would need some information about the possible ways to do this and the impact in term of CPU load.
Thank you,
Pascal
