Secure Certificate Usage
Secure Certificate Usage
I have used the NB SSL library for years, and I have successfully used it as part of an SMTP client on the SB70LC to send secure emails. Does the SB70LC require digitally signed certificates from a Certificate Authority to connect to the SMTP server, or does it only perform a secure handshake directly with the SMTP server? To wit, wouldn't such certificates eventually expire on my SB70LCs?

If that were true, wouldn't the same apply to a pc or phone sending email?

Frankly, I don't fully understand digital security. I assumed a PC or a phone would be "smart" enough to automatically update the various parts of digital security that they'd need to.
Perhaps Certificate Authorities (CA) and their certificates are not really used by my SB70LC. I think they are for authentication of a server, but are not involved when a client establishes a secure connection with an SMTP server. And, those connection "keys" never expire. That is, the NB SSL_SendMail() function doesn't use a CA at all.(?)
