Administrators of domain names under .CL that wish to implement DNSSEC, may do it in the zones under their control by creating a public key which has to be sent to NIC Chile. At its time NIC Chile will sign these keys and will create a chain of trust from .CL towards the domain name.
The upload of the keys is done through a system of DNSSEC update for every domain name in .CL. This operation could only be done by the authorized contacts for the domain name, using the private authorization code.
The format of the key should be DNSKEY or DS, up to a maximum of 10.
The DNSSEC control panel is located in https://www.nic.cl/cgi-bin/ingresa-solicitud?opcode=D (spanish version only).
You can find a help page with an example of upload in this page.
