KEYS AND PARAMETERS

Estonian Internet Foundation is using two key pair system (KSK + ZSK) for signing DNS records.

KSK (Key signing key) algortithm:RSA 2048
ZSK (Zone signing key) algorithm:RSA 1024
Denial of existence:NSEC3

Signatures are generated using SHA256 algorithm. The validity period of the signatures is random in between 14 to 28 days.

TTLs of DNSSEC records:

DNSKEY3600 seconds
DS3600 seconds
NSEC33600 seconds
RRSIG14-28 days

KEY ROLLOVER

All DNSSEC key material is generated and kept only in HSMs (Hardware Security Module). Keys are generated once a year
 
ZSK's are rolled over one in every quarter
KSK's are rolled overas required

EPP

.ee registry accepts only DNSKEY (<secDNS:keyData>) data. The registry system generates DS data automatically using SHA-256 algorithm.
