738ee1819e Fix DH_get_nid() so that it does not cache values.
DH_set0_pqg() is now responsible for caching the nid, q and length.

DH with or without named safe prime groups now default to using the maximum private key length (BN_num_bits(q) - 1)
when generating a DH private key. The code is now shared between fips and non fips mode for DH key generation.

The OSSL_PKEY_PARAM_DH_PRIV_LEN parameter can be used during keygen to override the maximum private key length to be
in the range (2 * strength ... bits(q) - 1). Where the strength depends on the length of p.

Added q = (p - 1) / 2 safe prime BIGNUMS so that the code is data driven (To simplify adding new names).
The BIGNUMS were code generated.

Fix error in documented return value for DH_get_nid

1d39620b34 PROV: Add the beginning of a DER writing library
This library is meant to be small and quick.  It's based on WPACKET,
which was extended to support DER writing.  The way it's used is a
bit unusual, as it's used to write the structures backward into a
given buffer.  A typical quick call looks like this:

    /*
     * Fill in this structure:
     *
     * something ::= SEQUENCE {
     *     id OBJECT IDENTIFIER,
     *     x [0] INTEGER OPTIONAL,
     *     y [1] BOOLEAN OPTIONAL,
     *     n INTEGER
     * }
     */
    unsigned char buf[nnnn], *p = NULL;
    size_t encoded_len = 0;
    WPACKET pkt;
    int ok;

    ok =   WPACKET_init_der(&pkt, buf, sizeof(buf)
        && DER_w_start_sequence(&pkt, -1)
        && DER_w_bn(&pkt, -1, bn)
        && DER_w_boolean(&pkt, 1, bool)
        && DER_w_precompiled(&pkt, -1, OID, sizeof(OID))
        && DER_w_end_sequence(&pkt, -1)
        && WPACKET_finish(&pkt)
        && WPACKET_get_total_written(&pkt, &encoded_len)
        && (p = WPACKET_get_curr(&pkt)) != NULL;

77de6bb38d Add perl support to parse and DER encode ASN.1 OID specs
We have an old OID database that's not as readable as would be
desired, and we have spots with hand coded DER for well known OIDs.

The perl modules added here give enough support that we can parse
OBJECT IDENTIFIER definitions and encode them as DER.

OpenSSL::OID is a general OID parsing and encoding of ASN.1
definitions, and supports enough of the X.680 syntax to understand
what we find in RFCs and similar documents and produce the DER
encoding for them.

oids_to_c is a specialized module to convert the DER encoding from
OpenSSL::OID to C code.  This is primarily useful in file templates
that are processed with util/dofile.pl.

96ebe52e89 Add EVP_PKEY_gettable_params support for accessing EVP_PKEY key data fields
Currently only RSA, EC and ECX are supported (DH and DSA need to be added to the keygen
PR's seperately because the fields supported have changed significantly).

The API's require the keys to be provider based.

Made the keymanagement export and get_params functions share the same code by supplying
support functions that work for both a OSSL_PARAM_BLD as well as a OSSL_PARAM[].
This approach means that complex code is not required to build an
empty OSSL_PARAM[] with the correct sized fields before then doing a second
pass to populate the array.

The RSA factor arrays have been changed to use unique key names to simplify the interface
needed by the user.

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.

adc9f73126 EVP: Clarify the states of an EVP_PKEY
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.

f552d90045 Add Serializers for EC
Provide EC serializers for text, pem and der.

EC parameters use ANS1 'CHOICE' - which means they are more embedded than other parameters used by
other KEY types (which normally have a SEQUENCE at the top level).
For this reason the ANS1_STRING type that was being passed around has been changed to a void so that the
code can still be shared with EC.

The EC serializer only supports named curves currently.

NOTE the serializer code assumes PKCS8 format - if the older encode methods are needed they will need to be
added in another PR. (Probably when deserialization is considered).

EVP_PKEY_key_fromdata_init was changed from using a keypair selection to all bits of a key. A side effect of this was
that the very restrictive checks in the ecx code needed to be relaxed as it was assuming all selection flags were non
optional. As this is not the case for any other key the code has been modified.

Fixed a bug in legacy_ctrl_str_to_params() - "ecdh_cofactor_mode" was being incorrectly converted to the wrong keyname.

called "provider". So, for example, instead of writing "default=yes" to
get algorithms from the default provider you would instead write
"provider=default". We also have a new "fips" property to indicate that
an algorithm is compatible with FIPS mode. This applies to all the
algorithms in the FIPS provider, as well as any non-cryptographic
algorithms (currently only serializers).

a377871db1 [PROV][KEYMGMT][EC] Import/export of priv_key as padded const time BN
For EC keys it is particularly important to avoid leaking the bit length
of the secret scalar.

Key import/export should never leak the bit length of the secret
scalar in the key.

For this reason, on export we use padded BIGNUMs with fixed length,
using the new `ossl_param_bld_push_BN_pad()`.

When importing we also should make sure that, even if short lived,
the newly created BIGNUM is marked with the BN_FLG_CONSTTIME flag as
soon as possible, so that any processing of this BIGNUM might opt for
constant time implementations in the backend.

Setting the BN_FLG_CONSTTIME flag alone is never enough, we also have
to preallocate the BIGNUM internal buffer to a fixed size big enough
that operations performed during the processing never trigger a
realloc which would leak the size of the scalar through memory
accesses.

Fixed length
------------

The order of the large prime subgroup of the curve is our choice for
a fixed public size, as that is generally the upper bound for
generating a private key in EC cryptosystems and should fit all valid
secret scalars.

For padding on export we just use the bit length of the order
converted to bytes (rounding up).

For preallocating the BIGNUM storage we look at the number of "words"
required for the internal representation of the order, and we
preallocate 2 extra "words" in case any of the subsequent processing
might temporarily overflow the order length.

Future work
-----------

To ensure the flag and fixed size preallocation persists upon
`EC_KEY_set_private_key()`, we need to further harden
`EC_KEY_set_private_key()` and `BN_copy()`.
This is done in separate commits.
