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.
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.
Use the ASN.1 decoder's SC_ASN1_BIT_FIELD decoder to properly decode
into a machine word. As _bitstring_extension is used only for the OID
2.5.29.15 by all callers, which is at most 9 bits wide, this is a
reasonable thing to do.
- fixes decoding of SecretKeyAttributes
- adds support for algorithmReferences
- adds support for algIndependentKeys (PKCS#15 Generic keys)
- implements encoding of SKDF
The code attempted to handle extensions assuming extensions were ordered. The
only extension it handled was crl's, but the handling was wrong and I didn't
find any actual use of the crl code. I've changed it to cache all the extensions
and then provided accessors functions to read a specific extension. I needed this
to read the key Usage, but the extension fetching code can work with any extension
(though the caller will need to parse the result. I also added code that parses DN
and returns a specifically requested DN component. I needed this to get the Common
Name for the certificate Subject. This gives the token a 'unique' name rather than
some generic name (like CAC-I or CAC-II). Both of these can be used to enhance the
piv support as well.

C_GetSessionInfo: Check whether a logout was done
Closes https://github.com/OpenSC/OpenSC/pull/624
rebased by @viktorTarasov
Removed cmap_record in sc_pkcs15_prkey_info (not used by any driver nor code)
Remove cardcf specific code (cardcf neutralized by CP_CACHE_MODE_NO_CACHE and it maintened by the Base CSP/KSP, not the minidriver)
Add conversion code for Windows GUID / OpenSC self computed GUID
needed to store information about EC curve supported by card.
Primary usage is when importing/generating key to get know if particular curve is supported by card.
framework-pkcs15: Duplicate public key related to private key rather than referencing the framework object
Referencing the related public key is required to return PKCS#11 attributes for a private key only available
in the public key object (i.e. CKA_MODULUS). This patch adds a copy of the public key to the private key object rather than
referencing the public key object in the framework. This prevents SEGV when the public key framework object
is deleted with C_DestroyObject, but the reference from the public key remains intact.
The bug leads to all kind of stability problems when keys are created and deleted in the same session.
The patch is in particular important if OpenSC is used with EJBCA or any other application using the
SUN PKCS#11 provider: When generating key pairs, then the public key object is eventually garbage collected
which removes the related object in the PKCS#11 module. Because there is no fixed time for this operation,
corruption occurs at random.
In a next step, the remaining related_xxx fields in sc_pkcs11_object should be revised and possibly removed.
framework: Added more error checking
sc_pkcs15_pubkey_from_spki_sequence() takes the ASN1 'subjectPublicKeyInfo' data
sc_pkcs15_pubkey_from_spki_fields() takes the ASN1 'subjectPublicKeyInfo' data without outter SEQUENCE tag
pkcs15: in pubkey-info data
* introduced new 'direct' 'raw' and 'spki' members
* removed 'encoded der data' member
* in 'read-public-key' try firstly SPKI direct value
pkcs11:
'direct' data used when getting CKA_VALUE attribute of public key
pkcs15init:
* initialize 'raw' and 'spki' direct public key value
New data are used to support the card specific minidriver on-card files.
Beeing included into internal pkcs15 data type,
these new data are accessible at the all frameworks: emulation of pkcs15 and pkcs15init, minidriver.
the proprietary on-card data can contain the GUIDs created by proprietary MW,
these data are parsed by card driver and put into the internal pkcs15 private key data
to be accesible in the different OpenSC frameworks
existing 'guid' obejct's data replaced by the one in private-key info
New CMAP record data used by pkcs15init emulator for the cards that have
the MD specific on-card data
The name implies what the format of the returned value, a SPKI.
The support for spki as a pkcs15 format of a pubkey, is extended to
work for any algorithm not just EC pubkeys. PKCS#15 appears to allow this.
sc_pkcs15_decode_pubkey_with_param will look for a SPKI
and attempt to use it for any algorithm, including RSA.
(RSA is the null case, as there are no algorithm parameters.)
sc_pkcs15_encode_pubkey_as_spki is exported from libopensc.
pkcs15-piv.c will use sc_pkcs15_encode_pubkey_as_spki to load public keys
as SPKI for RSA and EC.
The pubkey->data is never a SPKI, it is the DER encoding of the
pubkey without the parameters. If an spki is needed, use the
sc_pkcs15_encode_pubkey_as_spki to get the DER encoding of the spki.
As in the previous set of patches, pkcs15-tool.c will output both
sc_pkcs15_decode_pubkey_with_param and its internal.
This was left for testing, and the pubkey_pem_encode should be deleted
The original ECC code in OpenSC stored the ecpointQ as a DER encoded OCTET STRING.
Shortly before 0.13.0, code changes where made to store the ecpointQ as raw data
without the DER encoding.
Only some of the code was changed to support this but not all, and the comments
that said the ecpointQ was in DER where not changed either.
Some card drivers continued to work, using the original code in all place,
while some cards failed, as they where using a mixture of original code and
0.13.0 code.
This commit fixes these problems.
The ecpointQ is stored in raw format
A new structure type sc_pkcs15_u8 is defined.
The ecpointQ are changed to use the struct sc_pkcs15_u8. This was done to avoid
the confusion of using struct sc_pkcs15_der to hold non-DER encoded data.
(There may be other uses for this too...)
Comments are change is many places.
sc_pkcs15_decode_pubkey_ec was fixed to store the raw ecpointQ correctly.
sc_pkcs15_pubkey_from_spki was change to get the sc_ec_params from the alg_id
and fix up u.ec.params. Unfortunately the OpenSC code has two places EC parameters
are stored. They can get out of sync, or there may still be code
that looks in the wrng oplace. o(TODO get it to only only place.)
The u.ec.params.field_length is now set in a number of places, as this is need
in many of the PKCS#11 routines.
framework-pkcs15.c will now correctly return the DER encode ecpointQ,
for the CKA_EC_POINT attribute using pubkey->data which has the DER encoding
for the ecpointQ.
framework-pkcs15.c will look for the EC parameters in either the u.ec.params.der,
or in the alg_id->params. (TODO get it to only only place.)
pkcs15-myeid.c has some comments, as it looks like the code is storing a TLV
rather then a DER encoding of the ecpointQ. With the wrong encoding PKCS#11 will
return the wrong attribute for CKA_ECDSA_PARAMS.
pkcs15-piv.c is changed so emulation of a pubkey taken from a certificate will
work correctly.
New member keeps the value of the PKCS#15 DATA object.
Internal pkcs15 procedure that reads DATA object is modified
to check if requested data are already vailable in 'data-info',
an only then try to read the content of dedicated on-card file.
For some emulated PKCS#15 systems value of DATA object is kept as 'direct' value
in a proprietary attribute files and so the common read procedure could not be used.
; some efforts to unify layout of code source.
CK_VERSION is included into PKCS#11 data but is not specified by PKCS#15.
CK_VERSION can be provided by card's pkcs15 emulator or by the card's driver,
including the cards with the native support of pkcs#15 (and thus without pkcs15 emulator).
That's why the more general solution is to have these data included into 'sc-card' data type.
To hold the raw certificate blob in 'sc_pkcs15_cert' data use the 'sc_pkcs15_der' data type.
also:
; in 'pkcs15-cert.c' use short call of the debug messages;
; in 'destroy-object' pkcs15 framework handler take into account the multi-application cards:
-- when binding card use the application info;
-- when finalizing profile use the application ID.
When OpenSC is used with a card that enforces user_consent
and the calling PKCS#11 application does not understand how
to handle the CKA_ALWAYS_AUTHENTICATE, signature operations
will fail.
OpenSC will not cache a PIN that protects a user_consent
object as one would expect.
This mods allows PINs to be cached even if protecting a
user_consent object by adding
pin_cache_ignore_user_consent = true;
option in opensc.conf.
Thunderbird is the prime example of this situation.
Mozilla has accepted mods (357025 and 613507) to support
CKA_ALWAYS_AUTHENTICATE that will appear in NSS-3.14 but
this may be some time before this version is in vendor
distribution.
