SIM7070G Email Send Encrypted Mail with Encryption Port

GSM/GPRS Modules
#1

Hi everyone,

I am trying to port my sensor application from SIM900 to SIM7070G and I have the following problem:

For SIM900 I use the following command to encrypt transmission with encryption port
AT+EMAILSSL=1

For SIM7070G the related command from SIMCOM documents is the follwoing:
AT+EMAILSSL=1,0,“email.cer”,"email.pem"

Has anyone use it the above mentioned form? If yes how can I find “email.cer” and “email.pem” ?

Thanks and regards
