When the application (NSS) does not use WaitForSlotEvent and just
opportunistically tries to detect card and reader removals with
C_GetSlotInfo() and C_GetSessionInfo(), we might get errors in
various plcaes, in the sc_lock() function, when we try to transfer
other messages or when we ask for the reader status.
This is generally too late to call any disconnect functions because no
PC/SC handles are valid anymore. The reader state from PCSC
is searched by name so we can be pretty sure it is very similar
reader (with same name as the old one) and I hope we can reuse the
reader structure and just call the pcsc_connect() on that as we do
with invalid handles.
Otherwise we detect this issue in the refresh_attributes() (called
from C_GetSlotInfo()), where we can report the slot change in the
expected manner.
Fixes#1822
The negative integers were parsed uterly wrong, resulting in undefined
shift overflows as reported by oss-fuzz.
The current implementation takes negated values (properly masked) and
calculates two's complement in the end, which results in correct values
and correct data handling.

Changed four places where "<" should be "<=" so Le will be set correctly
Previous for 65K (extended) or 256 (short) Le is left set to 0.
This then caused Le to be to be not added to APDU as Le==0
Code later converts actual Le in APDU to be set to 0 to mean 256 or 65K.
SC_APDU_CASE_*_EXT are changed to SC_APDU_CASE_* so sc_detect_apdu_cse

sc-ossl-compat.h will check if OpenSSL has been built with or without some
deprecated defines. OpenSSL will provide defines for some of these if
built to still support depreacted routines but not if built with
"no-depracted". .
This commit will define some of the needed defines if ther are not
defined by OpenSSL. Thus if a distro builds OpenSSL with "no-depracted"
it can still be used.

When card supports SC_ALGORITHM_RSA_PAD_PKCS1 but not SC_ALGORITHM_RSA_HASH_NONE, then the DigestInfo need to be removed.
Current check make requires the card to not support both SC_ALGORITHM_RSA_PAD_PKCS1 and SC_ALGORITHM_RSA_HASH_NONE to have the removal done.
when importing a private key onto a pkcs15 card, if the card does not support
extended APDUs, we need to use chaining to store keys longer than 255 bytes.
While for RSA keys, this check was included, it was missing for EC keys.
This patch adds the SC_APDU_FLAGS_CHAINING flag to apdu.flags if data length is
greater than 255 and the card caps does not include SC_CARD_CAP_APDU_EXT.
Fixes#1747
Fixes regression from commit 3688dfe which did not consider that
the zero prefixing tests were too generic and matched EC keys too.
This simplifies the code even further and avoids data copying
when possible. Proper test is now included to do data value prefixing
only for the RSA keys it is needed.
Closes#1701.
At the point when gemsafe_match_card is called, the card type is already known,
either because of a previous match at card.c, or because it is forced at opensc.conf.
With this redundant match it's not possible to force selection on opensc.conf.

Encode the component ID to be key type and component ID. This allows
each combination to be unique and direct mapping to card component
ID type in the code by just taking the low byte. This simplifies
the code, and reduces confusion as there is now only one #define

MyEID starting version 4.5 supports 4K RSA keys. The card also
now supports proper APDU chainging (for sending large APDUs) and
receiving large responses via GET_RESPONSE splitting.
This updates the following:
* detection code properly announces 3K and 4K RSA support
when available
* APDU chaining is used when possible
* use ISO GET_RESPONSE handling for large responses
* max_recv_size is set to 256 which it always was supposed to be
as the old cards respond with that large responses too
* use the 2K signing kludge only on cards that need it
* unwrap and decipher code paths unified to the extent possible

Instead of a double check_sw call in case there is no data, assume
that a SW is properly sent by the card and do not expose
SC_ERROR_FILE_END_REACHED outside of the function
(like sc_pkcs15_read_file)
This is to facilitate Estonian eID 2018+ that instead of properly returning
6282 with trunkated data, 9000 is returned and next READ BINARY returns
6b00 (invalid p1/p2). The change should be generally harmless for well-behaving
cards.

Random data from PIV card is obtained using GENERAL AUTHENTICATE command
for a request of a Challenge from the card. "00 87 00 9B 04 7C 02 81 00"
Usually 8 bytes are returned.
NIST 800-73-3_PART2, "A.1 Authentication of the PIV Card Application Administrator"
"Table 11. Authentication of PIV Card Application Administrator" shows an example of
how to do this.
Some cards (one I have: 3b:7d:96:00:00:80:31:80:65:b0:83:11:17:d6:83:00:90:00)
will not allow 2 of these commands in a row. (Maybe assuming command is only
used as in Table 11 and is expecting the second command.)
Code was added to card-piv.c so if "6A 80" is returned, try the command one more time.
For any other GENERAL AUTHENTICATE failure, SC_ERROR_NOT_SUPPORTED is returned.
piv_get_challenge may be called within a loop from sc_get_challenge if more random
data is needed thus causing the the 2 commands to sent in a row.

Not all PIV applets are the same. Different versions of NIST 800-73 and improperly implemented
or not implemented required features of NIST 800-73 cases problems. Have a look at the card_issues
listed in card-piv.c. The PIV driver has tried to detect the differences based on clues found in
the ATR historical bytes and vendor version numbers for some cards.
At the same time it has tried to support the possibility there are multiple applets
on a card that the user may want to use at the same time from different applications.
This has lead to some detection problems with Dual CAC/PIV cards. The same cards
sold by the vendor may have only a PIV applet that may not be the same PIV applet that
is on the Dual PIV/CAC cards.
http://www.cac.mil/Portals/53/Documents/CAC-utilziation-and-variation-matrix-v2.03-20May2016.doc
defines a number of official CAC cards in active service. A table of the ATRs for these is now used
to detect these cards. The PIV version of the CCC is also read to see if any CAC PKI objects
are defined in the CCC, indicating it is a Dual CAC/PIV, even if the ATR is not listed.
A more conservative approach to try and handle multiple applets on a card is used. Based
on issues with the implementation of the PIV applet this may not be possible to do.
So for many cards no additional detection will be done at the start of every transaction,
and the login state can not be detected correctly.
ATRs for PIVKEY are also in the match table, as these cards have a log of issues.
Other PIV cards in the future or not yet tested may not be covered properly by this patch.
Extra debugging was added with "PIV_MATCH" to help with these other cards.
With "debug = 7;", `grep PIV_MATCH opensc-debug.log` can be used to see how a card
type and card_issues are derived.

pkcs15: added function to get a specific supported algorithm, checking also OID.
This is needed because for AES there are different OIDs for each key length.
For a problem description, see <https://github.com/OpenSC/OpenSC/issues/1524>.
In a nutshell, for a card with the CoolKey applet and 2048-bit keys,
the command
pkcs11-tool --test --login
fails to complete all of its tests.
This commit consists of a patch from @dengert.
To avoid triggering an error when the data exceeds 255 bytes, this commit
limits the amount of the payload sent to the CoolKey applet on the card based
on the maximum amount of data that the card can receive, and overhead bytes
(namely, a header and nonce) that accompany the payload.
With this change, the command
pkcs11-tool --test --login
succeeds.
Not yet complete, but can be run with CKA_TOKEN=FALSE set in the target object. Currently unwrapping emulated
with a decrypt operation in card-myeid.c. To be improved.
* Add minimal CAC1 driver for legacy cards.
It is using the same pkcs15 backend as the CAC2 cards as well as some of
the CAC2 driver methods.
The separation is made mostly for easier card matching or disabling.
Commit e5707b545e broke signing using minidriver on Windows.
More specifically changing #define SC_ALGORITHM_RSA_PAD_NONE from 0x00000000 to 0x00000001 caused a call to sc_pkcs1_encode() to fail as the padding algorithm was not specified anywhere in the CardSignData() implementation. It kind of worked as long as SC_ALGORITHM_RSA_PAD_NONE was 0x00000000, but the above mentioned commit broke this.
Now padding algorithm has to be explicitly specified, otherwise a call to sc_pkcs1_encode() will fail.
- rename 'keytype' in some OpenPGP-specific types to 'key_id'
because they key ID was what the field was used for
- introduce field 'algorithm' in the structures above
to indicate the key's algorithm: RSA, ...
- define constant SC_OPENPGP_KEYALGO_RSA and use it
- rename constants SC_OPENPGP_KEYFORMAT_* to SC_OPENPGP_KEYFORMAT_RSA_*
because they are RSA specific
List additional algorithms & attributes as supported only when the card
supports changing the algorithms attributes DOs and exposes this by having
the EXT_CAP_ALG_ATTR_CHANGEABLE capability set.
Using different algorithms and attributes requires changing the algorithm
attributes DOs. If that is not supported - as indicated by a missing
EXT_CAP_ALG_ATTR_CHANGEABLE capability - then only those algorithms
described by the current algorithms attributes DOs' contents can be used.
In addition simplify setting the flags.
* use variables if they are already there
* be a bit more explicit in logging
* more consistent tag format: %04X
* cleanup flag setting for _sc_card_add_rsa_alg()

A card driver may declare support for computing the padding on the card,
or else the padding will be applied locally in padding.c. All five
PKCS11 PSS mechanisms are supported, for signature and verification.
There are a few limits on what we choose to support, in particular I
don't see a need for arbitrary combinations of MGF hash, data hash, and
salt length, so I've restricted it (for the user's benefit) to the only
cases that really matter, where salt_len = hash_len and the same hash is
used for the MGF and data hashing.

Sc_asn1_read_tag can return SC_ERROR_ASN1_END_OF_CONTENTS
which indicates the tag and length are OK, but any value
is not completely contained in the buffer supplied. card-piv.c
can use this when reading just the beginning of a object to
determine the size of a buffer needed to hold the object.
As most of the drivers do not modify these, we can mark them as const.

md_pinpad_dlg_allow_cancel now defines whether or not the user is asked
before verifying the PIN on the PIN pad. This can be denied without
interaction with the PIN pad. A checkbox in the dialog allows the user
to change this setting, which is saved in the registry by the path of
the process.
This change fixes the progress bar to match the actual configured
timout. The progressbar now fills instead of running empty, which seemed
less frightening for most users.
This change also fixes some copy/paste errors in the documentation of
opensc.conf(5).
In Minidriver, when the DLL is called in multiple threads, this can
lead to a deinitialization of OpenSSL's OIDs in one thread making them
unavailable from other threads of the same process. As result, CVCs
cannot be veriefied anymore during chip authentication.
This removes code related to the old CAC 1 specification, while
preserving the CAC 2 functionality including CAC Alt token detection
for the tokens without CCC or ACA.
The detection based on SELECT APPLET APDU is improved to require also
the READ BUFFER APDU working, which should fail on misbehaving Java cards.

Previously, the code handled all the data objects as SimpleTLV,
which caused invalid encoding when we tried to merge TL + V buffers
into single PKCS#15 buffers.
This change is using GET PROPERTIES APDU after applet selection
to explore objects, figure out encoding and check the status of
PKI objects initialization to avoid reading them.
The previous solution was just guessing AIDs of the PKI objects
and trying if they answer.
This solution is inspecting card based on the Service Applet Table
(listing all the applets on the card) and using GET PROPERTIES APDU
listing all the available OIDs of the applet.
This was successfully tested with standard CAC card
(with different ACA AID) and uninitialized HID Alt tokens with empty
certificates slots.
