ISRG Root X1 in Consumer Devices


Hi everyone,

When people want to release a consumer product including “ISRG Root X1”, is there any condition to be concerned? For example, some contracts is required to be made between a company which wants to use the root certificate and ISRG before using the certificate. Do you have such condition?

Best Regards,

Browser/OS vendors with ISRG root in their root certificate stores

I’m not aware of any conditions around this.

@josh Is there anything to be aware of here?


You are welcome to distribute our root certificate unmodified on a nonexclusive and royalty-free basis. No contract is required.


@cpu, @josh

Thank you for your reply.
I understand that there is no condition to introduce the root certificate into consumer products.
