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. Reviewed-by:

We treat that as automatic success. Other EVP_*Update functions already do this (e.g. EVP_EncryptUpdate, EVP_DecryptUpdate etc). EVP_EncodeUpdate is a bit of an anomoly. That treats 0 byte input length as an error. Fixes #8576 Reviewed-by:

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'. Also coding-styles fixes from matcaswell Reviewed-by:

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. A simple setting of default flags fixes this problem. Fixes #8528 Reviewed-by:

OpenSSL will come with a set of well known providers, some of which need to be accessible from the start. These are typically built in providers, or providers that will work as fallbacks. We do this when creating a new provider store, which means that this will happen in every library context, regardless of if it's the global default one, or an explicitely created one. We keep the data about the known providers we want to make accessible this way in crypto/provider_predefined.h, which may become generated. For now, though, we make it simple and edited manually.

To ensure that old applications aren't left without any provider, and at the same time not forcing any default provider on applications that know how to deal with them, we device the concept of fallback providers, which are automatically activated if no other provider is already activated.

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. Reviewed-by:

openssl speed doesn't take into account that the library could be compiled without the support for the binary curves and happily uses them, which results in EC_GROUP_new_by_curve_name() errors. Reviewed-by:

'openssl pkeyutl' uses stat() to determine the file size when signing using Ed25519/Ed448, and this was guarded with OPENSSL_NO_POSIX_IO. It is however arguable if stat() is a POSIX IO function, considering that it doesn't use file descriptors, and even more so since we use stat() elsewhere without that guard. This will allow test/recipes/20-test_pkeyutl.t to be able to do its work for Ed25519/Ed448 signature tests. Reviewed-by:
