'pkcs15-tool --read-ssh-key' is now able to read NIST ECC keys from card.
Only 256, 384 and 521 field lengths are supported (same as allowed in
ssh-keygen -t ecdsa). Issue #803 is partialy fixed by this patch.

* Properly check lengths of retrieved values
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.
If cardos cards are initialized by other software and there is a pinref
without the msb set, also the pin verify works without that bit set.
This patch changes pin initialisation so that the pin is created in mf
which has the effect that pin verify works without | 0x80 to the
pin ref.

* new function sc_compacttlv_find_tag()
Add function sc_compacttlv_find_tag() to search for a tag in a
compact-TLV structure.
* OpenPGP: use sc_compacttlv_find_tag()
While doing so, fix a typo affection OpenPGP v3.x cards
opensc-notify doesn't propose a GUI that can be displayed to the users,
so it doesn't make sense to display it in the application list/launcher
Fixes: #1379
Instead ogf blindly using "%lu", use "%"SC_FORMAT_LEN_SIZE_T"u"
to cope with the various implementations.
This fixes a bug introduced in commit 20b1d829
Instead of simply searching for a trigger byte with the risk of
getting garbage, correctly parse historical bytes from ATR as well
as the "historical bytes" DO as compact TLV structures.
In addition
- prepare for additional data used in OpenPGP cards 3.x
- ignore [per the spec] chaining capability fo OpenPGP cards 1.x
This is also done in the official AusweisApp2 and avoids confusion with
other tokens that also have an EF.CardAccess and are capable of
verifying the PIN via PACE.
Fixes https://github.com/OpenSC/OpenSC/issues/1360
Let sc_get_challenge() do sc_lock() and loop through the card driver's
get_challenge() until enough bytes were collected. The card driver's
get_challenge() now returns the number of bytes collected (less or equal
than requested) or an error code.
- Allow more code re-use.
- PIV driver now uses ASN.1 parser for reading the random bytes
sc_pkcs15_verify_pin say:
/* if pin cache is disabled, we can get here with no PIN data.
* in this case, to avoid error or unnecessary pin prompting on pinpad,
* check if the PIN has been already verified and the access condition
* is still open on card.
*/
It then call sc_pkcs15_get_pin_info
A context specific login is used in PKCS#11 to force the user
to enter the PIN again and a verify command be sent to the card.
(Actually it could be a different value for the PINi depending on the card)
sc_pkcs15_get_pin_info will then call the card driver, but does not
say why it is testing the login status.sc_pkcs15_get_pin_info may return
SC_PIN_STATE_LOGGED_IN=1 and sc_pkcs15_verify_pin will then skip sending
the actual verify command to the card via _sc_pkcs15_verify_pin
To avoid this, sc_pkcs15_get_pin_info will set data.pin_type = pin_info->auth_method;
In the case of a context specific login, this is SC_AC_CONTEXT_SPECIFIC
and the card driver can take action and can return SC_PIN_STATE_LOGGED_IN=0
so the verify will be done.
The PIV driver card-piv.c does this. Other drivers could do something similar.

If a PIV card does not have or support a Discovery Object and
is known to lose the login state when the PIV AID is selected,
nothing was done in piv_card_reader_lock_obtained.
If was_reset > 0 select the PIV AID to at least get the
PIV AID selected.
For other cards either reading the Discovery a object and/or
selecting the PIV AID will make sure the PIV AID is selected.
If multiple applications are using the card, this will allow
the first one to select the AID, and any others that handle
a reset will not cause interference wit the first.

&& is replaced by || in the test of valid key references
for retired keys found in the Historic object.
For retired keys, the user_consent flag was being set by default.
Thus a C_Login(CKU_CONTEXT_SPECIFIC) would be required.
NIST 800-73 only requires PIN_Always on the Sign Key.
To extend the usefullnes of "retired keys" on non government
issued PIV-like cards, code had already been added
to use the certificate keyUsage flags to override the NIST
defined key usage flags. The NONREPUDATION flag is now used
to set the user_consent flag.
So rather then always requiring C_Login(CKU_CONTEXT_SPECIFIC)
for any retured key, the code only requires it for non government
cards where teh certificate has NONREPUDATION.

Don't pretend that we're capable of performing memory locking. The

Workaround to not detect the MUSCLE applet as whatever other card driver
selects an AID first. MUSCLE applet will always return 9000, which will
confuse other card drivers. Since this bug is not going to go away any
time soon, we simply detect the MUSCLE applet first and hope that other
applets don't have a similar bug.

The PKCS#15 emulation layer for the CAC uses a single PIN. Set its
label to "PIN" (rather than the card type "CAC I" or "CAC II"), so
that the PIN label will be omitted from the token label, providing
more space for the card holder name instead.
This is intended to match the behavior used for PIV cards, which
was changed with commit 56c8f59b25.
* Handle errors as intended in sc_pkcs15emu_openpgp_add_data()

this function when a data object cannot be read or is empty.
Improve existing comments for clarity.
* Address other compiler warnings when using --disable-optimization
Certain variables that are not initialized when they are declared
prevent the build from completing, when --disable-optimization is
passed to ./configure.
1. In epass2003_set_security_env, remove unused code, add condition

2. Line 1709 - add return check of hash_data
3. In epass2003_decipher API, the old sign using apdu.le = 256, now add
condition check of rsa
4. Line 2731-2734 - After login successful, need get session status,
adjust code, improve condition check of data->cmd.
Remove all the code related to the old GUI and PIN PAD.
This code was initially developed by Zetes and had the ability to
display a dialog to request the PIN to the user. It was also able to
manage some specific proprietary pin pads.
As the Belgian government/fedict has now its own implementation, all
these old crufts can be removed.

Some ActivIdentity CAC/PIV cards lose the login state when selecting
the PIV AID SC_CARD_TYPE_PIV_II_CAC and CI_PIV_AID_LOSE_STATE were added
so piv_card_reader_lock_obtained will try and do a SELECT PIV AID.
card->type is reset to its original value if piv_match_card_continued
fails to match a card as PIV.
pkcs15-piv.c now uses sc_card_ctl which checks card->ops->card_ctl for NULL.

We can't check for `tag == SC_ASN1_TAG_EOC` directly, because this
would also be true for a tag of 0x80 (with `class ==
SC_ASN1_CLASS_CONSTRUCTED`). So what we do is we check for the output
buffer to be NULL!

1. Buffer underrun in epass2003_decipher().
2. The parameter `data' in update_secret_key() must be constant.
(Discovered by Clang 4.0.0 on OpenBSD 6.2.)
Fixes#1286. The behaviour of pkcs11-tool will follow the standard -
send DER. If EC_POINT_NO_ASN1_OCTET_STRING is defined then it will
write plain bytes.
ATR and differences between 3.4/3.5 are based on

Framework-pkcs15.c will now set pin_info->auth_method to SC_AC_CONTEXT_SPECIFIC
iso7816.c iso7816_build_pin_apdu treats this the same as SC_AC_CHV
card-piv.c piv_pin_cmd sets priv->xcontext_specific=1 and calls sc_lock before
the verify command. If the verify fails sc_unlock is called.
Later after the next card command returns, if priv->context_specific==1 piv_check_sw
will call sc_unlock as the application may not have requested the crypto but
some other command.
Some additional calls to sc_lock and sc_unlock have been added to make sure
PIV internal command sequences including the crypto command ('87') and any get
responses are always protected by a lock.
This guarantees the card is locked for verify and the next command
which should be the crypto operation. The PIV card also inforces this restriction
on the card.
This is based on suggestions in:

Many OpenSC drivers try and detect during match if the card supports
their AID by doing a SELECT FILE for the AID.
But this can cause problems with cards such as Yubico that do not ignore
SELECT AID commands for applications they do not support. Other cards may
have the same problems. Selecting the wrong AID can also lose the security
state.
The card-piv.c will now uses the GET DATA to read the PIV Discovery Object '7E'
which is a ISO standard template that will contain the AID of the currently
active application. The driver will then double check that the template is
for the PIV application.
If the template contains the PIV AID, then no SELECT AID is done.
PIV standards say there can only be one PIV application on a card.
PIV standards also say PIV must be the the default application,
but Yubico does not follow this.
The command fails only then will a SELECT AID be done.
Thus this can avoid the Yubico problem.
This logic is used in both "match" and in the piv_card_reader_lock_obtained
routine.
Additional logic was in piv_card_reader_lock_obtained was added to handle
when the card reset was received by some other program. Multiple programs
may be trying to use the PIV application on the card, and thus multiple
programs will all receive that the card was reset. The first program to receive
the card was reset will do all of the above logic, and may leave the card in
a state will cause other programs to not have to do much at all.
The intent of all of this is to avoid sending extra commands to the card
including SELECT AID that could change the card state when not needed.

Use names that are specific to EAC, not the German ID card (nPA),
because Protocol and Commands are defined by BSI TR-03110 and ICAO.
Functions that are nPA specific are moved to card-npa.h.
RutokenS returns data with little endian byte order, due to this
fact token wouldn't work with standard function. So function for
parsing fcp from little endian data was inplemented.
The maximum length for sending and receiving data can now be found in DO
7F66. For now, we just use the default values for short/extended length
capabiliites.
PKI-Applets may not be active if the card has been reset or unpowered.
The SELECT command used to activate the applet, is identical to the one
used during card matching or initialization.
Some "unfriendly" cards return SW 90 00 to any instruction including
the ACA file selection and therefore they are identified as CAC card.
To avoid this, we will try to read the assumed ACA file and we will
mark the card as matched only if we will read something from that file.
We do not parse the content yet.
To avoid infinite loop on "unfriendly" cards, we assume that
read data instruction always returns some data. It it does not,
we can safely assume the file is not there or it is not the card
we are looking for.
Windows/macOS (minidriver/tokend) handle the authentication status and
perform an explicit logout on shutdown. PKCS#11 standard requires a
session for logging into the card; when closing the session we perform
an explicit logout. Hence, the authentication status should be reset
even if not performing a reset on disconnect.
partially implements https://github.com/OpenSC/OpenSC/issues/1215
Refactored OpenPGP code so that future versions of the card will be
accessed using the logic for OpenPGP V2. We hope that backward
compatibility of the standard will keep the new versions functional.
CardDeleteContext may be called at any time, interrupting any ongoing
operation with the same PCARD_DATA. This leads to a race condition when
CardDeleteContext deletes, for example, the sc_context_t which the
interrupted call still wants to access. We have seen and fixed this
problem in https://github.com/OpenSC/OpenSC/issues/973 specifically for
the PIN entry process, however, it also applies to all other calls to
the md.
The new implementation removes the need for global data in the md.
