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.

2020-04-20Fix DH_get_nid() so that it does not cache values.Shane Lontis
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.

2020-03-25EVP: Implement support for key downgrading in backendsRichard Levitte
Downgrading EVP_PKEYs from containing provider side internal keys to containing legacy keys demands support in the EVP_PKEY_ASN1_METHOD. This became a bit elaborate because the code would be almost exactly the same as the import functions int EVP_KEYMGMT. Therefore, we end up moving most of the code to common backend support files that can be used both by legacy backend code and by our providers.

2020-03-23DH, DSA, EC_KEY: Fix exporters to allow domain parameter keysRichard Levitte
The export-to-provider functions for DH, DSA and EC_KEY assumed that a public key is always present, and would fail if not. This blocks any attempt to export a key structure with only domain parameters. While fixing this, we also modify the selection declaration to evp_keymgmt_import() to be more adaptive, the diverse selection bits are now added when the corresponding data is added to the OSSL_PARAM array.

This should have been publically present a long time ago, to be consistent with the RSA, DSA and EC_KEY APIs.

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.

2020-02-07Redesign the KEYMGMT libcrypto <-> provider interface - the basicsRichard Levitte
The KEYMGMT libcrypto <-> provider interface currently makes a few assumptions: 1. provider side domain parameters and key data isn't mutable. In other words, as soon as a key has been created in any (loaded, imported data, ...), it's set in stone. 2. provider side domain parameters can be strictly separated from the key data. This does work for the most part, but there are places where that's a bit too rigid for the functionality that the EVP_PKEY API delivers. Key data needs to be mutable to allow the flexibility that functions like EVP_PKEY_copy_parameters promise, as well as to provide the combinations of data that an EVP_PKEY is generally assumed to be able to hold: - domain parameters only - public key only - public key + private key - domain parameters + public key - domain parameters + public key + private key To remedy all this, we: 1. let go of the distinction between domain parameters and key material proper in the libcrypto <-> provider interface. As a consequence, functions that still need it gain a selection argument, which is a set of bits that indicate what parts of the key object are to be considered in a specific call. This allows a reduction of very similar functions into one. 2. Rework the libcrypto <-> provider interface so provider side key objects are created and destructed with a separate function, and get their data filled and extracted in through import and export. (future work will see other key object constructors and other functions to fill them with data) Fixes #10979 squash!
