Azure_iot_hub expiration date X509 certificates

[AngeldelaCalle]

Hi all,

I have a problem. I'm using a mix of the nrf samples azure_fota and azure_iot_hub connecting to Azure, using certificates X.509.
The problem is the expiration date, that's one month by default. I would want to know if there's any possibility of extending significantly this expiration date or authenticating using another method like DPS or simmetric key.

Many thanks in advance.

Hello again,

The validity period of the device certificates can be extended by changing input parameters to the openssl command (or the tool you are using) when generating the certificates. 

Please have a look at Azure's own documentation on creating test certificates using openssl.

I hope this will help you!

Regards,

Markus
