See also: rt.perl.org #76138 Fix: rt.cpan.org #64552 and rt.cpan.org #79606 Support for private-key-format v1.3 Fix: rt.cpan.org #75892 Do not canonicalize the "Next Domain Name" rdata field of a NSEC RR for draft-ietf-dnsext-dnssec-bis-updates-17 compliance. BUG FIX/FEATURE: validation of wildcard RRs now available. Duane Wessels is acknowledged for submitting the initial code on which this fix is based. FIX: case sensitivity of ownername during DS generation (Acknowledgements Jens Wagner) ***0.16 March 12, 2010 Feature: KEY inherits DNSKEY This helps maintenance in one part of the code. Feature: keylength methode rt.cpan.org #53468 Added keylength method for RSA and DSA Acknowledgements Hugo Salgado Fix: rt.cpan.org #51778 Empty bitmap would cause error about undefined ARRAY in NSEC/NSEC3. Now the code will allow empty bitmaps gracefully Feature: New Algorithm Support (rt.cpan.org #51092) SHA2 algorithm support, including NSEC3 algorithm parameters updated Acknowledgement Jakob Shlyter Fix: rt.cpan.org #42089 NSEC3 Algorithm support in NSEC3 broken patch by Wes Hardaker ***0.15 December 31, 2008 Fix: digestbin not set when an empty value passed to hash. Feature: Added DLV (rfcc 4431). The RR object is simply a clone of the DS RR and inherits ... everything Feature: Added NSEC3 and NSEC3PARAM support (RFC5155). This adds Mime::Base32 to the module dependency list. The RR type was still experimental at that time and is maintained in Net::DNS::RR. Fix: Test script recognizes change in Time::Local. Note that Time::Local does not deal with dates beyond 03:14:07 UTC on Tuesday, 19 January 2038. Therefore this code has a year 2038 problem. Fix: DS create_from_hash now produces objects that can create wireformat. Other: minor changes to the debug statements added t/05-rr.t (and identified a couple of bugs using it) Fix: a few inconsistencies with respect to parsing of trailing dots. During development the test signatures generated with the BIND tools were re-generated in order to troubleshoot a bug that (most probably) was caused by a version incompatibility between Net::DNS and Net::DNS::SEC. Before release the original test from the 0.14 release were ran against this version too. 0.14 February 14, 2005 FIX: The introducion of the keytag warning triggered a bug with RSAMD5 keys, causing RSAMD5 keys not to be loaded. 0.13 December 9, 2005 FEAT: rt.cpan.org 14588 Added support for passing (a reference to) an array of keys to the RRSIG verify function. FIX/FEAT: The Net::DNS::SEC::Private function will for RSA based keys verify if the keytag in the filename is actually correct. Since at parsing the value of the DNSKEY RR flags is not known we test against the currently defined flag values 256 and 257. If we cannot find a keytag match a warning is printed and Private key generation fails This inconsistency was spotted by Jakob Shlyter. FEAT: Added support for SHA256 to the DS RR. Assigned the expected digest type2 for SHA256 type hashes. Note that this makes the Net::DNS::SEC depend on Digest::SHA instead of Digest::SHA1. The default digest type is still set to 1. NB. The code makes assumptions about the IANA assignment of the digest type. The assignment may change. Do not use SHA256 in production zones!! FIX: rt.cpan.org #15662 Roy Arends noticed and patched the label counting did not ignore an initial asterisk label. FIX: Wes Hardaker noticed the default TTL values for created signatures to be different from the TTLs from the data that is being signed. FIX: Wes Hardaker reported there was a problem with validating RRsets that had ownernames with capitals. The fix depends on a fix in Net::DNS::RR that is available in version 0.53_03 or later of the Net::DNS distribution. FEAT: Propper dealing with mnemonics for algorithm and digest type added to DS FIX/FEAT: Mnemonics were written as RSA/MD5 and RSA/SHA1. This has been corrected tp RSASHA1 and RSAMD5, as in the IANA registry. 0.12_02 June 6, 2005 (beta 2 release for 0.13) Bug: new_from_hash would not correctly create the RR since internally typebm is used to store the data this has been fixed so that the following works Net::DNS::RR->new(name=>$name, ttl=>$ttl, type=>"NSEC", nxtdname=>$nxtdname, typelist=>join(" ",@types) ); FEAT: Introduced the "use bytes" pragma to force character interpretation of all the scalars. Any utf processing by perl makes the code behave unpredictable. 0.12_01 April 18, 2005. (beta release for version 0.13) FEAT (!!!): Changed the symantics of the Net::DNS::Keyset::verify method. Read the perldoc for details. The requirement that each key in a keyset has to be selfsigned has been loosened. FEAT: Added a "carp" to the new methods of the NXT RR. Warning that that record is depricated. FEAT: Cleaned the tests so that RRSIG and DNSKEY are used except for SIG0 based tests. FEAT: Changed the name of the siginceptation[SIC] to siginception. Thanks Jakob Schlyter for notifying me of this mistyping. An alias for the method remains available. FEAT: Renamed unset_sep() to clear_sep(). NOTE: To avoid confusion the Net::DNS::SIG::Private class has been removed. Use Net::DNS::SEC::Private! DOC: Added references to RFC 4033, RFC 4034 and RFC 4035. Rewrote parts of the perlpod. 0.12 June 2004 "DNSSEC-bis Release" FEAT: Added utility function key_difference() to Net::DNS::SEC. See perlpod for details. I needed this in other software and figured they are generic enough to make them available through this module. FEAT: Modified some functions to use DNSKEY and RRSIG instead off KEY and SIG. - Net::DNS::Keyset now uses DNSKEY and RRSIG. - the demo function getkeyset.pl now uses DNSKEY too. FEAT: Added the possibility to create a keyset out of two arrays of dnskey and rrsig object. FEAT: Added some helperfunctions to Net::DNS::SEC::Private to read X509 formated private keys and dump them into bind format. This functionality has not been tested well. BUG : When reading a RRSIG from a packet the signame would not have a trailing dot. 0.11_4 Apr 24 2004 Development snapshot. BUG: - Fixed MANIFEST. FEAT: Removed critical dependency on bubblebabble. It is available to DS if installed but not critically dependend. 0.11_3 Mar 4 2004 Development snapshot. BUG: - Fixed minor in signing unknown RR types. 0.11_2 Jan 27 2004 Development snapshot. FEAT: - Prelimanary support for draft-ietf-dnssec-nsec-rdata-02. This depends on support for unknown RR types (Net::DNS version 0.44) 0.11_1 Sep 23 2003 Development snapshot. FEAT: - To be able to deal with argument supplied as either mnemonics or by value the Net::DNS::SEC::argument method was created. It can be used as a class method but it is also inherited by Net::DNS::RR::RRSIG and Net::DNS::RR::DNSKEY. 0.11 August 28 2003 FEAT: - Implemented draft-ietf-dnsext-dnssec-2535typcode-change-04.txt This document has been through review and will be published as standard track RFCs shortly. (Publsished as RFC3755). IMPORTANT: the implementation of the typecode roll deprecated the use of SIG->create for any other reason than SIG0. If you try to create SIGs over RRsets you will be warned. FEAT: - Modified the namespace for the module that holds the name of the private key from Net::DNS::RR::SIG::Private to Net::DNS::SEC::Private. !!!!! Net::DNS::RR::SIG::Private will be deprecated in a next release. !!!!! CLEAN:- Crypt::OpenSSL::RSA v 0.19 introduced the possibility to create keys directly from parameters, although this introduced a dependency on Crypt::OpenSSL::Bignum it allowed to get rid from converting all parameters to DER/ANS1 encoding. Got rid of a number of lines of code. 0.10 January 8 2003 BUG: - Crypt::OpenSSL::RSA::new method has been depricated. Code has been modified to deal with the new constructors 0.09 January 6 2003 FEAT: - Added Net::DNS::RR::SIG::Private. The class provides an abstraction to the private key material. The SIG create method now either takes a filename, like previously, or a Private key object as an argument. If you have to create many signatures the latter is preferred because you only have to read the file with the private key material once. Note that by adding this feature a modification to Net::DNS::Resolver was needed to properly do SIG0. Use Net::DNS version 0.32 or later in combination with this version FEAT: - Wes Griffen added a parameter change to keyset: 'Attached is a diff for Net::DNS::SEC v0.8 that adds a parameter changes keyset->writekeyset($path) to keyset->writekeyset($prefix,$path) where prefix is an optional string that is prepended to the filename of the keyset. That way I can keep my unsigned keyset in keyset-. and have the signed keyset in signed-keyset-.' FEAT: - Babblebubble, handy for telephone confirmation of hashes. Added babblebubble string as comment to DS RR. DS->babble returns the babble bubble string FEAT: - Miek Gieben contributed demo/key2ds 0.08 November 4 2002 BUG: - DSA signature verification failed at random about 1 per 10 sigatures. Corrected allignment problem that lead to this. Added 'stresstest' that loops over creation and verification of signatures to spot these kind of seldomly occuring errors. On my VAIO PII 500Mhz the take about a minute: Files=3, Tests=3056, 69 wallclock secs (63.30 cusr + 0.70 csys = 63.99 CPU) FEAT: - Added Test::More as dependency as on some systems diag was failing. 0.07 October 2 2002 FEAT: - Added demo/make-signed-keyset, a contribution by Wes Griffin. FEAT: - Removed dependency on Math::Pari by porting away from Crypt::DSA to Crypt::OpenSSL::DSA (version 0.10). This should increase portability over platform. T.J. Mather, the Crypt::OpenSSL::DSA maintainer has been particularly helpfull and responsive by adding a few methods to the DSA modules. 0.06 August 16 2002 NOTE: In one of ther versions prior to Net::DNS 0.26 a bug got introduced that made Net::DNS::SEC break. The bug was fixed in version 0.27. BUG: - Check on the existence of the private file improved in SIG.pm - signame got trailing dot with the create methods and not with others. FEAT: - Added privatekeyname method to KEY.pm - Started work on Net::DNS::Keyset. - Added RSA/SHA1 (algorithm ID 5) to SIG.pm. Patch supplied by Andy Vaskys, Network Associates Laboratories. - Rewrote regexp's to not use $' (Postmatch). 0.05 and 0.04 June 17, 2002 BUG: Makefile.PL needed a fix for unused dependency. This failed made the installation fail :-(. 0.04 introduced another failing dependency. DOC: Clarified the documentation at points. 0.03 June 14, 2002 DOC: Few Clarifications 0.02 June 4, 2002 First CPAN Release. Some modifications to the packaging. 0.01 May 25, 2002 Version 0.01 of the package is an alpha for CPAN release. --------------------------------------------------------------------------- The extensions used to be published as a modified version of Net::DNS. The history of those is documented below. 0.20-DNSSEC-0.2: Branched off Net::DNS version 0.20 release (CPAN May 15, 2002) 0.20-DNSSEC-0.1: This version had limited distribution First patch against a version 0.20 snapshot (2002-03-27). http://www.dyndns.org/~ctriv/net-dns-snaps/2002/03/ Modified t/09-dnssec.t; uses Test::More now and includes a number of self consistency checks. DOC Cleaned up the documentation and removed some references to functions and libraries that where not used anyway. FIX 'aesthetic' patch supplied by Simon Josefsson reordering the NXT RR map for the print method. FEAT Added checks on keytype and updated to latest specs for DS Added SIG0 support. See Net::DNS::Packet for details. The verify and create methods of SIG.pm where modified somewhat to cope with the difference. Changed RSA backend from Crypt::RSA to Crypt::OpenSSL::RSA because Crypt::RSA failed during a 'loss of Math::Pari precision in Crypt::Primes'. 0.19-DNSSEC-0.5: BUG DS create method: Hash calculation was done over concattination of name and key material while the hash should be taken over concatenation of canonical name and key rdata. (Fix by Mike Schiraldi) 0.19-DNSSEC-0.4: Added CERT support: Courtesy of Mike Schiraldi for VeriSign BUG Fixed MANIFEST file. make dist will result in proper module tar ball 0.19-DNSSEC-0.3: Solved patch problems that where due to the $Id$ in headers not being from the original distribution. Added DSA signature creation Added DS support You have to uncomment line 77 in Net/DNS.pm to fully enable DS This will assign QTYPE 93 to the DS RR. That value is not assigned by IANA. Added this README.DNSSEC file Added t/09-dnssec.t to the test script with a number of consistency checks. after patching the original distribution direction perl Makefile.PL make test will call this function among other things. BUG KeyID set to 0 for null keys. BUG Sorting of canonical RDATA; Data over which SIG was created was not sorted properly (RFC2535 sect 8.3) causing signature verification errors for RDATA within a RRset having different length (e.g. some NS RRsets would not verify.) 0.19-DNSSEC-0.2: First somewhat public release. --------------------------------------------------------------------------- $Id$
