1.6.17 2014-01-10
* Fix ldns_dnssec_zone_new_frm_fp_l to allow the last parsed line of a
zone to be an NSEC3 (or its RRSIG) covering an empty non terminal.
* Add --disable-dane option to configure and check availability of the
for dane needed X509_check_ca function in openssl.
* bugfix #490: Get rid of type-punned pointer warnings.
Thanks Adam Tkac.
* Make sure executables are linked against libcrypto with the
LIBSSL_LDFLAGS. Thanks Leo Baltus.
* Miscellaneous prototype fixes. Thanks Dag-Erling Smørgrav.
* README now shows preferred way to configure for examples and drill.
* Bind to source address for resolvers. drill binds to source with -I.
Thanks Bryan Duff.
* -T option for ldns-dane that has specific exit status for PKIX
validated connections without (secure) TLSA records.
* Fix b{32,64}_{ntop,pton} detection and handling.
* New RR type TKEY, but without operational practice.
* New RR types HIP, NINFO, RKEY, CDS, EUI48, EUI64, URI, CAA and TA.
* New output format flag (and accompanying functions) to print certain
RR's as unknown type
* -u and -U parameter for ldns-read-zone to mark/unmark a RR type
for printing as unknown type
* bugfix #504: GPOS RR has three rdata fields. Thanks Jelte Jansen.
* bugfix #497: Properly test for EOF when reading key files with drill.
* New functions: ldns_pkt_ixfr_request_new and
ldns_pkt_ixfr_request_new_frm_str.
* Use SNI with ldns-dane
* bugfix #507: ldnsx Fix use of non-existent variables and not
properly referring to instance variable. Patch from shussain.
* bugfix #508: ldnsx Adding NSEC3PARAM to known/allowable RR type
dictionary. Patch from shussain.
* bugfix #517: ldns_resolver_new_frm_fp error when invoked using a NULL
file pointer.
* Fix memory leak in contrib/python: ldns_pkt.new_query.
* Fix buffer overflow in fget_token and bget_token.
* ldns-verify-zone NSEC3 checking from quadratic to linear performance.
Thanks NIC MX (nicmexico.mx)
* ldns-dane setup new ssl session for each new connect to prevent hangs
* bugfix #521: drill trace continue on empty non-terminals with NSEC3
* bugfix #525: Fix documentation of ldns_resolver_set_retry
* Remove unused LDNS_RDF_TYPE_TSIG and associated functions.
* Fix ldns_nsec_covers_name for zones with an apex only. Thanks Miek.
* Configure option to build perl bindings: --with-p5-dns-ldns
(DNS::LDNS is a contribution from Erik Ostlyngen)
* bugfix #527: Move -lssl before -lcrypto when linking
* Optimize TSIG digest function name comparison (Thanks Marc Buijsman)
* Compare names case insensitive with ldns_pkt_rr_list_by_name and
ldns_pkt_rr_list_by_name_and_type (thanks Johannes Naab)
* A separate --enable for each draft RR type: --enable-rrtype-ninfo,
--enable-rrtype-rkey, --enable-rrtype-cds, --enable-rrtype-uri and
--enable-rrtype-ta
* bugfix #530: Don't sign and verify duplicate RRs (Thanks Jelte Jansen)
* bugfix #505: Manpage and usage output fixes (Thanks Tomas Hozza)
* Adjust ldns_sha1() so that the input data is not modified (Thanks
Marc Buijsman)
* Messages to stderr are now off by default and can be reenabled with
the --enable-stderr-msgs configure option.
1.6.16 2012-11-13

* Fix typo in exporting b32_* symbols to make pyldns load again

* Building from repository
If you are building from the repository you will need to have (gnu)
autotools like libtool and autoreconf installed. A list of all the commands
needed to build everything can be found in README.svn. Note that the actual
needed to build everything can be found in README.git. Note that the actual
commands may be a little bit different on your machine. Most notable, you'll need to run libtoolize (or glibtoolize), if you skip this step, you'll get an error about missing config.sub.

5. Base 32 Encoding
The Base 32 encoding is designed to represent arbitrary sequences of
octets in a form that needs to be case insensitive but need not be
humanly readable.
A 33-character subset of US-ASCII is used, enabling 5 bits to be
represented per printable character. (The extra 33rd character, "=",
is used to signify a special processing function.)
The encoding process represents 40-bit groups of input bits as output
strings of 8 encoded characters. Proceeding from left to right, a
40-bit input group is formed by concatenating 5 8bit input groups.
These 40 bits are then treated as 8 concatenated 5-bit groups, each
of which is translated into a single digit in the base 32 alphabet.
When encoding a bit stream via the base 32 encoding, the bit stream
must be presumed to be ordered with the most-significant-bit first.
That is, the first bit in the stream will be the high-order bit in
the first 8bit byte, and the eighth bit will be the low-order bit in
the first 8bit byte, and so on.
Each 5-bit group is used as an index into an array of 32 printable
characters. The character referenced by the index is placed in the
output string. These characters, identified in Table 3, below, are
selected from US-ASCII digits and uppercase letters.

8 I 17 R 26 2
Special processing is performed if fewer than 40 bits are available
at the end of the data being encoded. A full encoding quantum is
always completed at the end of a body. When fewer than 40 input bits
are available in an input group, zero bits are added (on the right)
to form an integral number of 5-bit groups. Padding at the end of
the data is performed using the "=" character. Since all base 32
input is an integral number of octets, only the following cases can
arise:
(1) the final quantum of encoding input is an integral multiple of 40
bits; here, the final unit of encoded output will be an integral
multiple of 8 characters with no "=" padding,
(2) the final quantum of encoding input is exactly 8 bits; here, the
final unit of encoded output will be two characters followed by six
"=" padding characters,
(3) the final quantum of encoding input is exactly 16 bits; here, the
final unit of encoded output will be four characters followed by four
"=" padding characters,
(4) the final quantum of encoding input is exactly 24 bits; here, the
final unit of encoded output will be five characters followed by
three "=" padding characters, or
(5) the final quantum of encoding input is exactly 32 bits; here, the
final unit of encoded output will be seven characters followed by one
"=" padding character.
6. Base 32 Encoding with Extended Hex Alphabet
The following description of base 32 is due to [7]. This encoding
should not be regarded as the same as the "base32" encoding, and
should not be referred to as only "base32".
One property with this alphabet, that the base64 and base32 alphabet
lack, is that encoded data maintain its sort order when the encoded
data is compared bit-wise.
This encoding is identical to the previous one, except for the
alphabet. The new alphabet is found in table 4.
