I have successfully implemented opendnssec. I have multiple domains at
GoDaddy and while all other TLDs work after inputting the results from
ods-ksmutil key ds-seen -z domain.co -x 12345
the domains with the .co TLD have an extra input field which is required.
Instead of the usual
Key Tag:
Algorithm:
Digest Type:
and
Digest:
There is one more required field called Key Data Alg in which the tool-tip
states:
"The key data algorithm determines the method used for encrypting the
public key. Values must be an integer between 0 and 255 and must match the
server."

In the comments section at the bottom, Christian Elsen says:
"Here is what these fields mean along with possible values:
– flags: 256 for Zone Signing Keys (ZSK), 257 for Key Signing Keys (KSK)
You want 257 for the long-term Key Signing Key in this case
– protocol: always 3 to signify DNSSEC
– key data alg: 5 for RSA with SHA1 (currently the only specified choice)
– public key: base64 format of the public key (either ZSK or KSK)"
and
"You can also lookup the correct values via “dig type48 examples.com”
against your domain. "
In the specifics of
https://support.godaddy.com/help/article/6114/about-self-managed-dnssec
titled About Self-Managed DNSSEC it seems to be missing the information
regarding this required Key Data Alg: input field in their DS form.
"ods-ksmutil key export --zone domain.co --verbose" reveals:
domain.co. 3600 IN DNSKEY 257 3 8

;{id = 65105 (ksk), size = 2048b}
GoDaddy's support was of no help.
The possibilities for Key Data Alg: are 1,2,3,5,6,7,8,10,12
I tried all of them and received a momentary failure email.

Peter
