Fixing this took way too long; I should have earlier explained the
code to a co-hacker to find the problem myself in my code by this.
--
These are non-substantive corrections for minor spelling mistakes
within the GnuPG codebase.
With something like this applied to the codebase, and a judiciously
tuned spellchecker integrated as part of a standard test suite, it
should be possible to keep a uniform orthography within the project.

(parse_p12): Use p12_parse_free_kparms.
--
Take care: We allow parsing of a second private key but we are not yet
able to import the second private key.
The whole things is required to at least import the certificates of
current pkcs#12 files as created by the German Elster tax system. No
test data, sorry.
* sm/minip12.c: Factor parsing code out to ...
* common/tlv-parser.c: new. Extend function names and provide a few
extra functions.
* common/Makefile.am (common_sources): Add new file.
* sm/minip12.c: Adjust to use the new parser API.

tlv_expect_sequence.

--
This patch improves the BER parser by simplifying it. Now tlv_next
pops off and thus closes all containers regardless on whether they are
length bounded or ndef. tlv_set_pending is now always used to undo
the effect of a tlv_next in a loop condition which was terminated by a
nesting level change.
Instead of using the length as seen in the decrypted container we now
remove the padding and let the BER parser do its work. This might
have a negative effect on pkcs#12 objects which are not correctly
padded but we don't have any example of such broken objects.
GnuPG-bug-id: 6752
* sm/minip12.c (_tlv_push): Handle NDEF more correctly.
(tlv_expect_octet_string): Do not bail out on NDEF.
(dump_tag_info): Print some more infos.
--
We do not have a complete test case for this. We need to further
analyze T6752 to see what Mozilla is doing here. In any case with
this patch we get a bit further and don't bail out at the ndef.
GnuPG-bug-id: 6536, 6752
* sm/minip12.c (oid_hmacWithSHA1): New. Also for the SHA-2 algos.
(digest_algo_from_oid): New.

(crypt_block): Ditto.
(decrypt_block): Ditto.
(parse_bag_encrypted_data): Parse the optional prf part and get the
hmac algorithm.

(p12_build): Pass SHA1 for digest_algo.
* sm/t-minip12.c (run_one_test): Print failed values in verbose mode.
* tests/cms/samplekeys/nistp256-openssl-self-signed.p12: New.
* tests/cms/samplekeys/Description-p12: Add this one.

--
This supports the modern algorithms, i.e. using SHA256 for the KDF
which is the default in openssl unless the -legacy option is used.
GnuPG-bug-id: 6536
* sm/minip12.c (need_octet_string_cramming): New.
(tlv_expect_object, tlv_expect_octet_string): Run the test before
cramming.
* sm/minip12.c (ENABLE_DER_STRUCT_DUMPING): New but undefined macro
for debug purposes.
(bag_decrypted_data_p, bag_data_p): Use macro to allow dumping.
--
This bug was exhibited by importing a gpgsm exported EC certificate.
We use an extra test instead of retrying to allow retruning an error
from malloc failure. And well, for easier reading of the code.
GnuPG-bug-id: 6536
* sm/minip12.c (struct bufferlist_s): New.
(struct tlv_ctx_s): Add bufferlist.
(tlv_register_buffer): New.

input_consumed value anymore.

* tests/cms/samplekeys/Description-p12: Add them.
* tests/cms/Makefile.am (EXTRA_DIST): Add samplekeys.

This should finish the rewrite of the pkcsc#12 parser for now. More
fun is likely to come.
GnuPG-bug-id: 6536, 5793
* sm/minip12.c: Reworked most of the parser.
(p12_set_verbosity): Add arg debug and change all callers.

* sm/Makefile.am (module_maint_tests): Move t-Minit to ...
(module_tests): here.
* tests/cms/samplekeys/Description-p12: New.
--
Note that cram_octet_string stuff has not yet been reworked. I need
to locate the sample files first.
GnuPG-bug-id: 6536
* sm/minip12.c (struct p12_parse_ctx_s): New. Use this instead of
passing several parameters to most functions.
(parse_pag_data): Factor things out to ...
parse_shrouded_key_bag): new.
(parse_cert_bag): New.
(parse_bag_data): New.
(p12_parse): Setup the parse context.
--
To support newer pkcs#12 files like those issued by the DFN we need to
support another ordering of data elements. This rework reflects the
P12 data structure a bit better than our old ad-hoc hacks. Tests could
only be done with the certificate parts and not the encrypted private
keys.
GnuPG-bug-id: 6037

--
GnuPG-bug-id: 4757
* sm/minip12.c [TEST]: Remove test code. Include util.h, tlv.h. and
openpgpdefs.h. Remove the class and tag constants and replace them by
those from tlv.h.

(build_key_sequence): Rename to ...
(build_rsa_key_sequence): this.
(build_ecc_key_sequence): New.
(p12_build): Call RSA or ECC builder.
(p12_raw_build): Ditto.
* sm/export.c (gpgsm_p12_export): Use correct armor header for ECC.

Observed by Joshua Rogers <honey@internot.info>, who proposed a
slightly different fix.
Debian-Bug-Id: 773472
Added fix at a second place - wk.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
