2021-02-22Add EVP_PKEY_public_check_quick.Shane Lontis
Adding the EVP_PKEY_param_check_quick() reminded me that there are also partial checks for public keys as part of SP800-56A for FFC (DH named safe prime groups) and ECC. The code was mainly already there and just needed to be plumbed into the validate methods.

2021-02-15Implement EVP_PKEY_param_check_quick() and use it in libsslMatt Caswell
The low level DH API has two functions for checking parameters: DH_check_ex() and DH_check_params_ex(). The former does a "full" check, while the latter does a "quick" check. Most importantly it skips the check for a safe prime. We're ok without using safe primes here because we're doing ephemeral DH. Now that libssl is fully using the EVP API, we need a way to specify that we want a quick check instead of a full check. Therefore we introduce EVP_PKEY_param_check_quick() and use it.

2020-03-25EVP: Clarify the states of an EVP_PKEYRichard Levitte
EVP_PKEY is rather complex, even before provider side keys entered the stage. You could have untyped / unassigned keys (pk->type == EVP_PKEY_NONE), keys that had been assigned a type but no data (pk->pkey.ptr == NULL), and fully assigned keys (pk->type != EVP_PKEY_NONE && pk->pkey.ptr != NULL). For provider side keys, the corresponding states weren't well defined, and the code didn't quite account for all the possibilities. We also guard most of the legacy fields in EVP_PKEY with FIPS_MODE, so they don't exist at all in the FIPS module. Most of all, code needs to adapt to the case where an EVP_PKEY's |keymgmt| is non-NULL, but its |keydata| is NULL.

2020-02-29Rethink the EVP_PKEY cache of provider side keysRichard Levitte
The role of this cache was two-fold: 1. It was a cache of key copies exported to providers with which an operation was initiated. 2. If the EVP_PKEY didn't have a legacy key, item 0 of the cache was the corresponding provider side origin, while the rest was the actual cache. This dual role for item 0 made the code a bit confusing, so we now make a separate keymgmt / keydata pair outside of that cache, which is the provider side "origin" key. A hard rule is that an EVP_PKEY cannot hold a legacy "origin" and a provider side "origin" at the same time.

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!
