Subject: [PATCH 2/6] pkcs11-tool - use valid data for decription tests
In tests, make sute test data is either padded, or "zero" padded
so size if data <= modlen - 11. The smallest pad in 11 bytes,
00 | NN | PS | 00. PS is at least 8 bytes.
"zero" padding has N = 00, PS >= 8 byte of 00.

Subject: [PATCH 3/6] Increase SC_MAX_SUPPORTED_ALGORITHMS from 8 to 16
CardOS cards may have more then 8 supported_algo_info entries in tokenInfo.
We may bemissing some. We have seen 8 in some pkcs15-tool -i -v output.
Simple fix is to incrase the limit. More appropriate fix is to remove the limit,
much like is done with sc_algorithm_info. and use realloc of the array.

Subject: [PATCH 4/6] sc_supported_algo_info - Put ECDSA OID as inline
Mismatch of ASN1 parsing of tokeninfo.supported_algos[n].paramters
in one place parameter was treated as a pointer to sc_object_id
and in another as inline structure. This caused segfaults
in pkcs15-tool when it tried to print the OID.

Subject: [PATCH 5/6] pkcs15-tool.c - print Supported_algorithms from tokenInfo
Some cards can provide supported algorithms in tokenInfo
which contain ECDSA OID, and PKCS11 mechanism
Don't know how many Algo_refs were actually read,
and a ref of 0 may be valid. print at least one Algo_refs.
Print the mechanism from PKCS11, and print operations
Use the $(top_srcdir)/src/pkcs11/pkcs11-display.c on Unix
Use the $(TOPDIR)\src\pkcs11\pkcs11-display.obj on Windows
pkcs15.tool.c treat ECDSA OID as inline
pkcs15-tool prints PKCS11 mechanisms using pkcs11-display.c
Automake now warns that the default will change, in the future
so "[subdir-objects]" is added to configure.ac

Subject: [PATCH 6/6] Various CardOS V5_* improvements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Treat CardOS V5_0 and V5_3 cards differently then older versions:
Use card->dvr_data as a pointer to cardos_data_t to store private driver
data to pass internally, especially between set security environment
and the crypto operations. Sc_get_encoding_flags sets sec_flags from
algo_info->flags in pkcs15-sec.c and it passed to decipher.
Some cards when doing a decipher may drop leading 00 byte when
returning data from RSA_RAW decipher. Add leading byte(s) as needed.
Get Cryptographic Mechanism Reference from Key Reference:
Key reference byte appears to be a 4 bit Cryptographic Mechanism Reference
and a 4 bit key reference.
This is only done if key reference & 0xF0 != 0 i.e. default Cryptographic
mechanism reference is 0. which appears to be the case for RSA RAW.
PKCS1 appears to be 0x10 and ECDSA 0x30
See iso 7816-4 table 55 for DST:
84 Reference of a private key
95 Usage qualifier byte - Table 57 - 40 looks OK
80 Cryptographic mechanism reference and referes to section 9.2
The 4 bit key reference limits card to 16 keys. In future this may not work,
but we can derive a Cryptographic Mechanism Reference from what OpenSC
thinks the card needs to do. Only know RSA RAW, PKCS1 and ECDSA.
ECDSA code has not been tested, but expected to work.
Allow setting CardOS type and flags from opensc.conf using card_atr stanza
This is a fallback if newer cards are added or older cards have problems
giving us time to make need changes in next release.
It will help in identifying what flags are needed for each card.
As user can report what combination of flags work for them. They do this by
adding to opensc.conf with something like this. (Change the ATR to your card's ATR):
card_atr 3b:d2:18:00:81:31:fe:58:c9:03:16 {
driver = "cardos";
# type is decimal from cards.h:
# SC_CARD_TYPE_CARDOS_V5_0 is 1009
# SC_CARD_TYPE_CARDOS_V5_3 is 1010
type = 1010;
# flags is hex from opensc.h:
#define SC_ALGORITHM_ONBOARD_KEY_GEN 0x80000000
#define SC_ALGORITHM_NEED_USAGE 0x40000000
#define SC_ALGORITHM_RSA_RAW 0x00000001 /* RSA_RAW is PAD_NONE */

flags = 80000101;

For V5_0 and v5_3 cards, use sc_get_max_send_size and sc_get_max_recv_size
which takes care or reader sizes even on Windows where SCardControl can not get PART_10 sizes.
(commit eddea6f3c2d3dafc2c09eba6695c745a61b5186f on Windows forces reader sizes to 255, 256
in reader-pcsc.c if not already set. It should not do this, but leave that up to card drivers.)
pkcs15-cardos.c added:
New file, pkcs15-cardos.c, added as emulation only for CardOS
V5_0 and V5_3 cards.
sc_pkcs15_bind_internal is called to get tokenInfo as CardOS
cards are substantially PKCS15 cards. But some V5_* cards have
errors in the tokenInfo, Which are corrected.
For older CardOS cards, card-cardos.c will create all the
card->algorithms.
Pkcs15-cardos.c will check for card->algorithms and if there
are none, it will do the following:
SC_CARDCTL_CARDOS_PASS_ALGO_FLAGS is called twice. First to get
the flags as set by user via opensc.conf card_atr or default
flags set by the card driver. Then after determining from the
tokenInfo what algorithms the card can support, the new flags
are passed to card_cardos.c to create card->algorithms.
https://atos.net/wp-content/uploads/2018/11/CT_181026_LPM_CardOS_V5-3_Multifunctionality_FS_en3_web.pdf
says card supports: "“Command chaining” in accordance with ISO/IEC 7816-4"
To take advantage of this with older readers, max_send_size and max_recv_size
is now based on minimum of reader limits and "data_field_length" from card.
This should allow card to work in older readers not capable of extended APDU.
So far current cards we have seen do no appear to support “Command chaining”.
