5056133cc7 Avoid setting gen_type to -1 in dsa_gen_set_params
gh_gen_type_common_set_params looks up a dsa contexts gen_type using
name2id, but if it returns error, we inadvertently set gctx->gen_type to
-1, which is an invalid value, which may lead to improper behavior in
future calls, in the event that said future calls preform an operation
of the form;
if (gen_type == <VALID VALUE>) {
        do_stuff
else {
        do_other_stuff
}

Technically it is not correct to continue with the operations on the
gen context after failed parameters setting but this makes it more
predictable.

Fix it by assigning the result of a lookup to a stack variable, and only
update gctx->gen_value if the lookup returns a non-failing value

In leiu of testing this specific case, also add an ossl_assert in dsa_gen
to validate the gen_val input prior to continuing, should other code
points attempt to do the same thing

f3090fc710 Implement deterministic ECDSA sign (RFC6979)
This PR is based off the contributions in PR #9223 by Jemmy1228.

It has been modified and reworked to:
(1) Work with providers
(2) Support ECDSA and DSA
(3) Add a KDF HMAC_DRBG implementation that shares code with the RAND HMAC_DRBG.

A nonce_type is passed around inside the Signing API's, in order to support any
future deterministic algorithms.

944f822aad Fix EVP todata and fromdata when used with selection of EVP_PKEY_PUBLIC_KEY.
The private key for rsa, dsa, dh and ecx was being included when the
selector was just the public key. (ec was working correctly).
This matches the documented behaviour.

cf33379997 PROV: Add type specific PKCS#8 decoding to the DER->key decoders
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.

3a37ddde91 Fix DSA EVP_PKEY_param_check() when defaults are used for param generation.
Fixes #14480

An internal flag that is set during param gen was not being tested, so
the wrong type was used to select the dsa domain param validation method.

In the default provider - if no gen_type is set then by default the fips186_4 gentype
will be selected when pbits >=2048 otherwise it selects fips186_2.
The fips provider ignores the gen_type and always uses fips186_4.

Before this change dsa used fips186_2 by default in the default
provider.

6963979f5c DECODER: Adjust the library context of keys in our decoders
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.

b425001010 Rename OPENSSL_CTX prefix to OSSL_LIB_CTX
Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,
e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER.

The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

4f2271d58a Add ACVP fips module tests
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.

0abae1636d EVP: Implement support for key downgrading in backends
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.
