2021-03-19PROV: Add type specific PKCS#8 decoding to the DER->key decodersRichard Levitte
This required refactoring a number of functions from the diverse EVP_PKEY_ASN1_METHOD implementations to become shared backend functions. It also meant modifying a few of them to return pointers to our internal RSA / DSA/ DH / EC_KEY, ... structures instead of manipulating an EVP_PKEY pointer directly, letting the caller do the latter.

2020-12-17DECODER: Adjust the library context of keys in our decodersRichard Levitte
Because decoders are coupled with keymgmts from the same provider, ours need to produce provider side keys the same way. Since our keymgmts create key data with the provider library context, so must our decoders. We solve with functions to adjust the library context of decoded keys, and use them.

2020-12-05DSA: Make DSA_bits() and DSA_size() check that there are key parametersRichard Levitte
Without these check, a DSA structure without key parameters will cause these functions to crash. This is also the case in pre-3.0 OpenSSL, but since we now extract these data early, to cache them in the EVP_PKEY structure, the same crash happens earlier and much more internally. The added checks are of the same kind as DSA_security_bits() already does. Fixes #13610 Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/13611)

However, that makes it impossible to use these functions with an engine or a provider that happens to implement DSA. This change solves that problem by shuffling these functions to more appropriate places.

2020-10-19Fix no-dhMatt Caswell
One of the x509 tests checks to make sure spurious errors don't appear on the stack. The x509 app uses the OSSL_STORE code to load things. The OSSL_STORE code will try various different formats - which results in lots of failures. However those failures are typically suppressed by OSSL_STORE unless they are interesting. OSSL_STORE thinks it knows what kind of errors are uninteresting (ASN.1 errors) but gets confused if upper levels of code add additional errors to the stack. This was happening in the DSA code which confused OSSL_STORE and meant the errors were not being suppressed properly - and hence the x509 test failed. Interestingly this only impacts a no-dh build, because in a no-dh build the DSA param decoder suddenly becomes the last to be tried. If it happens earlier in the list the errors end up getting suppressed anyway. The simplest solution is to just to remove the error from the DSA param decoder code. It's not adding any useful information anyway.

2020-07-09Add multiple fixes for ffc key generation using invalid p,q,g parameters.Shane Lontis
Fixes #11864 - The dsa keygen assumed valid p, q, g values were being passed. If this is not correct then it is possible that dsa keygen can either hang or segfault. The fix was to do a partial validation of p, q, and g inside the keygen. - Fixed a potential double free in the dsa keypair test in the case when in failed (It should never fail!). It freed internal object members without setting them to NULL. - Changed the FFC key validation to accept 1024 bit keys in non fips mode. - Added tests that use both the default provider & fips provider to test these cases.

2020-06-17Add ACVP fips module testsShane Lontis
For FIPS validation purposes - Automated Cryptographic Validation Protocol (ACVP) tests need to be performed. (See https://github.com/usnistgov/ACVP). These tests are very similiar to the old CAVS tests. This PR uses a hardwired subset of these test vectors to perform similiar operations, to show the usage and prove that the API's are able to perform the required operations. It may also help with communication with the lab (i.e- The lab could add a test here to show a unworking use case - which we can then address). The EVP layer performs these tests instead of calling lower level API's as was done in the old FOM. Some of these tests require access to internals that are not normally allowed/required. The config option 'acvp_tests' (enabled by default) has been added so that this access may be removed. The mechanism has been implemented as additional OSSL_PARAM values that can be set and get. A callback mechanism did not seem to add any additional benefit. These params will not be added to the gettables lists.

DH_set0_pqg() is now responsible for caching the nid, q and length. DH with or without named safe prime groups now default to using the maximum private key length (BN_num_bits(q) - 1) when generating a DH private key. The code is now shared between fips and non fips mode for DH key generation. The OSSL_PKEY_PARAM_DH_PRIV_LEN parameter can be used during keygen to override the maximum private key length to be in the range (2 * strength ... bits(q) - 1). Where the strength depends on the length of p. Added q = (p - 1) / 2 safe prime BIGNUMS so that the code is data driven (To simplify adding new names). The BIGNUMS were code generated.

2020-03-09EVP: Check that key methods aren't foreign when exportingRichard Levitte
The EVP_PKEY_ASN1_METHOD function export_to() must check that the key we're trying to export has a known libcrypto method, i.e. is a built in RSA_METHOD, DSA_METHOD, etc. Otherwise, the method may be defined by the calling application, by an engine, by another library, and we simply cannot know all the quirks hidden behind that method, if we have access to the key data, or much anything. Such keys are simply deemed impossible to export to provider keys, i.e. have export_to() return 0. This cascades back to functions like evp_pkey_export_to_provider() and evp_pkey_upgrade_to_provider() and their callers. In most cases, this is fine, but if these get mixed in with provider side keys in any function, that function will fail.
