Given ZSK signatures are more common than KSK ones, it is desirable to be able to parametrize both values independently.
After a complete process, the signature file is obtained. When I use the ldns-verify-zone tool to verify the file, the error occured. The error is :

Hi,
Is it possible to sign with your tool both the domain and the subdomains (for which DS and NS records are provided, they use their own DNS servers.)
Thank you.
Hay que sacar la creación de las llaves de la sesión de firmado, porque las llaves pueden ser de PKCS11 o de algún archivo.

Finally I found that there is no $ORIGIN include in zone file, hsm-tools can't get the exactly domain name.
After I added the $ORIGIN example.com., i got the whole signed zone.
my suggestions:
I have a problem. I download root.zone from the root server and delete the signature information in it,then re-sign it with ./dns-tools sign pkcs11 -p ./dtc.so -f ./root.zone -3 -z . -o root.zone.signed -c
, and I find it cannot be signed.

Hi. I have the tool running using libdtc as HSM. I can sign zones without problem. But it uses the same key pair ZSK and KSK.
How can I generate a new key pair for each zone? I tried modifying the dns-tools.config by defining a different key-label for each zone, but it ignores it and insists on using the original ones it generated.
Thanks.
When I run the dtcnode in ipv6 server, the error occured. Will you release a version that supports IPv6 in the future?

dns-tools verify is giving the error "Zone Digest: error parsing zone: dns: Error hexadecimal wrong size:.." when its input zone has a TYPE63 RR with spaces inside the RDATA. Spaces are allowed in RFC3597 section 5, and named-checkzone returns ok, but dns-tools fails to parse the record.
Here I attach an example zone. If you remove the space, the verify succeeds.

Hi. When I sign a zone the output gives the corresponding DS record with a SHA1 digest.
DS with SHA1 is deprecated. Can you please change it to SHA256, or give both DS?
Thanks.
When signing a zone, the NSEC and NSEC3 records are lacking of the "DNSKEY" type in the apex of the domain.
This can cause problems with validators using "aggressive caching", and also a security problem with DoS and replay attacks.
For example in a live test zone, signed with a fresh dns-tools:
$ dig ns1.dtc.dnssec.lab.nic.cl. cname +dnssec

There's no "DNSKEY" type in the NSEC bitmap answer, but certainly there're DNSKEY records in the zone.

Signature Calculation
A signature covers the RRSIG RDATA (excluding the Signature Field)
and covers the data RRset specified by the RRSIG owner name, RRSIG
class, and RRSIG Type Covered fields. The RRset is in canonical form
(see Section 6), and the set RR(1),...RR(n) is signed as follows:
signature = sign(RRSIG_RDATA | RR(1) | RR(2)... ) where
"|" denotes concatenation;
RRSIG_RDATA is the wire format of the RRSIG RDATA fields
with the Signer's Name field in canonical form and
the Signature field excluded;
RR(i) = owner | type | class | TTL | RDATA length | RDATA
"owner" is the fully qualified owner name of the RRset in
canonical form (for RRs with wildcard owner names, the
wildcard label is included in the owner name);
Each RR MUST have the same owner name as the RRSIG RR;
Each RR MUST have the same class as the RRSIG RR;
Each RR in the RRset MUST have the RR type listed in the
RRSIG RR's Type Covered field;
Each RR in the RRset MUST have the TTL listed in the
RRSIG Original TTL Field;
Any DNS names in the RDATA field of each RR MUST be in
canonical form; and
The RRset MUST be sorted in canonical order.
RSIG RR Example
The following RRSIG RR stores the signature for the A RRset of
host.example.com:
host.example.com. 86400 IN RRSIG A 5 3 86400 20030322173103 (
20030220173103 2642 example.com.
oJB1W6WNGv+ldvQ3WDG0MQkg5IEhjRip8WTr
PYGv07h108dUKGMeDPKijVCHX3DDKdfb+v6o
B9wfuh3DTJXUAfI/M0zmO/zz8bW0Rznl8O3t
GNazPwQKkRN20XPXV6nwwfoXmJQbsLNrLfkG
J5D6fwFm8nN+6pBzeDQfsS3Ap3o= )
The first four fields specify the owner name, TTL, Class, and RR type
(RRSIG). The "A" represents the Type Covered field. The value 5
identifies the algorithm used (RSA/SHA1) to create the signature.
The value 3 is the number of Labels in the original owner name. The
value 86400 in the RRSIG RDATA is the Original TTL for the covered A
RRset. 20030322173103 and 20030220173103 are the expiration and
inception dates, respectively. 2642 is the Key Tag, and example.com.
is the Signer's Name. The remaining text is a Base64 encoding of the
signature.
Note that combination of RRSIG RR owner name, class, and Type Covered
indicates that this RRSIG covers the "host.example.com" A RRset. The
Label value of 3 indicates that no wildcard expansion was used. The
Algorithm, Signer's Name, and Key Tag indicate that this signature
can be authenticated using an example.com zone DNSKEY RR whose
algorithm is 5 and whose key tag is 2642.
Canonical DNS Name Order
For the purposes of DNS security, owner names are ordered by treating
individual labels as unsigned left-justified octet strings. The
absence of a octet sorts before a zero value octet, and uppercase
US-ASCII letters are treated as if they were lowercase US-ASCII
letters.
To compute the canonical ordering of a set of DNS names, start by
sorting the names according to their most significant (rightmost)
labels. For names in which the most significant label is identical,
continue sorting according to their next most significant label, and
so forth.
For example, the following names are sorted in canonical DNS name
order. The most significant label is "example". At this level,
"example" sorts first, followed by names ending in "a.example", then
by names ending "z.example". The names within each level are sorted
in the same way.
example
a.example
yljkjljk.a.example
Z.a.example
zABC.a.EXAMPLE
z.example
\001.z.example
*.z.example
\200.z.example
Canonical RR Form
For the purposes of DNS security, the canonical form of an RR is the
wire format of the RR where:
1. every domain name in the RR is fully expanded (no DNS name
compression) and fully qualified;
2. all uppercase US-ASCII letters in the owner name of the RR are
replaced by the corresponding lowercase US-ASCII letters;
3. if the type of the RR is NS, MD, MF, CNAME, SOA, MB, MG, MR, PTR,
HINFO, MINFO, MX, HINFO, RP, AFSDB, RT, SIG, PX, NXT, NAPTR, KX,
SRV, DNAME, A6, RRSIG, or NSEC, all uppercase US-ASCII letters in
the DNS names contained within the RDATA are replaced by the
corresponding lowercase US-ASCII letters;
4. if the owner name of the RR is a wildcard name, the owner name is
in its original unexpanded form, including the "*" label (no
wildcard substitution); and
5. the RR's TTL is set to its original value as it appears in the
originating authoritative zone or the Original TTL field of the
covering RRSIG RR.
I use the dnssec-keygen to generate two keys:
Kkbenet.com.%2B003%2B00851.key.+005+37875**.key**
Kkbenet.com.%2B003%2B00851.key.+005+37875**.private** and sign the zone with it.
The dns-tools have two key files(KSK and ZSK) to sign the zone, but its format is .pem.
The question is : if I want to use the key which is generated by dnssec-keygen to sign the zone file, any methods can be adopted? Or do I have anyway to change the .key and .private to .pem?
The digest tests are based on the [zone examples of the RFC proposal]. However, two of them (MultiZONEMD, SignedZone) fail (this is, the computed digest is different than the example digest). We need to check deeply why they fail. This could be related to problems with sorting or wire formatting.
I also checked other implementations cited on the RFC draft (one in C by the authors, and one in Python). I could not acheive to obtain the same ZONEMD between all the implementations in some zones. Fruther testing is needed to understand the reasons of the differences.
When I use the branch V1.1.0 of HSM-Tool, after compilation, execute “ ./hsm-tools sign pkcs11 -p ./dtc.so -f ./example.com -3 -z example.com -o example.com.signed -c”,the Error "Error: Input File Path not Specified" occurs.But there is no problem with using other versions.
Similar to #4, in SoftHSMv2, when this function executes, it throws the following error:
SecureDataManager.cpp(431): Invalid IV in encrypted data
P11Attributes.cpp(281): Internal error: failed to decrypt private attribute value
Hi. I couldn't find a way to configure the salt and iterations in case of NSEC3 signing.
I think the default should be empty salt and 0 iterations, as is the current recommendations, but it should be configurable with something like [--nsec3-iterations [0..100]] [--nsec3-salt-length [1..64]|--nsec3-salt-value <string>]
(if given only salt-length, it should generate a random one with the provided length)
Thanks.
It would be nice to have NSEC3 also implemented
