2023-04-03FFC cleanupsslontis
Discovered during coverage testing. Remove unneccesary check when using ossl_dh_get0_params() and ossl_dsa_get0_params(). These point to addresses and can not fail for any existing calls. Make dsa keygen tests only available in the FIPS module - as they are not used in the default provider. Change ossl_ffc_set_digest() to return void as it cannot fail.

2023-02-07Fix NULL deference when validating FFC public key.slontis
Fixes CVE-2023-0217 When attempting to do a BN_Copy of params->p there was no NULL check. Since BN_copy does not check for NULL this is a NULL reference. As an aside BN_cmp() does do a NULL check, so there are other checks that fail because a NULL is passed. A more general check for NULL params has been added for both FFC public and private key validation instead.

2022-07-18Use as small dh key size as possible to support the securityTomas Mraz
Longer private key sizes unnecessarily raise the cycles needed to compute the shared secret without any increase of the real security. We use minimum key sizes as defined in RFC7919. For arbitrary parameters we cannot know whether they are safe primes (we could test but that would be too inefficient) we have to keep generating large keys. However we now set a small dh->length when we are generating safe prime parameters because we know it is safe to use small keys with them. That means users need to regenerate the parameters if they want to take the performance advantage of small private key.

2020-12-16EVP_PKEY & DH: Make DH EVP_PKEY_CTX parameter ctrls / setters more availableRichard Levitte
EVP_PKEY_CTX_set_dh_ functions were only available when DH was enabled ('no-dsa' not configured). However, that makes it impossible to use these functions with an engine or a provider that happens to implement DH. This change solves that problem by shuffling these functions to more appropriate places. By consequence, there are a number of places where we can remove the check of OPENSSL_NO_DH. This requires some re-arrangements of internal tables to translate between numeric identities and names.

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.

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.
