BCrypt support unless the user sets _WIN32_WINNT.  That wasn't the

DH_check is used to test the validity of Diffie-Hellman parameter sets (p, q, g). Among the tests performed are primality tests on p and q, for this BN_is_prime_ex is called with the rounds of Miller-Rabin set as default. This will therefore use the average case error estimates derived from the function BN_prime_checks_for_size based on the bit size of the number tested.

However, these bounds are only accurate on testing random input. Within this testing scenario, where we are checking the validity of a DH parameter set, we can not assert that these parameters are randomly generated. Thus we must treat them as if they are adversarial in nature and increase the rounds of Miller-Rabin performed.

Generally, each round of Miller-Rabin can declare a composite number prime with probability at most (1/4), thus 64 rounds is sufficient in thwarting known generation techniques (even in safe prime settings - see https://eprint.iacr.org/2019/032 for full analysis). The choice of 64 rounds is also consistent with SRP_NUMBER_ITERATIONS_FOR_PRIME 64 as used in srp_Verify_N_and_g in openssl/apps/s_client.c.

So far, it only handled hash-and-algorithm pairs from TLS1.2,
now it also handles 'schemes' defined in TLS1.3 like 0x0807=ed25519 or
0x0809=rsa_pss_pss_sha256

Now it prints information in one of these formats:

... Algorithm scheme=ecdsa_secp256r1_sha256, security bits=128 ... TLS1.3
... Algorithm digest=SHA384, algorithm=DSA, security bits=192  ... TLS1.2
... Algorithm scheme=unknown(0x0e01), security bits=128        ... unhandled case

To implement this added three new lookup-tables: signature_tls13_scheme_list,
signature_tls12_alg_list, signature_tls12_hash_list.

Also minor changes in 'security_callback_debug', eg adding variable 'show_nm'
to indicate if we should show 'nm'.

Great effort has been made to make initialization more configurable.
However, the behavior of OPENSSL_config() was lost in the process,
having it suddenly generate errors it didn't previously, which is not
how it's documented to behave.

The ecdh_c array is allocated of the same size as ecdh_choices,
whose size depends on whether the support for binary curves is enabled
or not.  (The same goes for ecdsa_c).
On systems without SIGALRM, ecdh_c is indexed by predefined constants
intended for representing the index of the ciphers in the ecdh_choices
array.
However, in case of NO_EC2M some of the #defined constants won't match
and would actually access the ecdh_c out-of-bounds.

Use enum instead of a macro to define the curve indexes so they're
within the bounds of the ecdh_c array.

There are two copy-paste errors in handling CTR mode. When dealing
with a 2 or 3 block tail, the code branches to the CBC decryption exit
path, rather than to the CTR exit path.

This can lead to data corruption: in the Linux kernel we have a copy
of this file, and the bug leads to corruption of the IV, which leads
to data corruption when we call the encryption function again later to
encrypt subsequent blocks.
