Update core_names.h fields and document most fields. 

Renamed some values in core_names i.e Some DH specific names were changed to use DH instead of FFC.
Added some strings values related to RSA keys.
Moved set_params related docs out of EVP_PKEY_CTX_ctrl.pod into its own file.
Updated Keyexchange and signature code and docs.
Moved some common DSA/DH docs into a shared EVP_PKEY-FFC.pod.
Moved Ed25519.pod into EVP_SIGNATURE-ED25519.pod and reworked it.

Added some usage examples. As a result of the usage examples the following change was also made:
ec allows OSSL_PKEY_PARAM_USE_COFACTOR_ECDH as a settable gen parameter.

=head1 DESCRIPTION
The EVP_PKEY_CTX_get_params() and EVP_PKEY_CTX_set_params() functions allow
transfer of arbitrary key parameters to and from providers.
Not all parameters may be supported by all providers.
See L<OSSL_PROVIDER(3)> for more information on providers.
See L<OSSL_PARAM(3)> for more information on parameters.
These functions must only be called after the EVP_PKEY_CTX has been initialised
for use in an operation.
These methods replace the EVP_PKEY_CTX_ctrl() mechanism. (EVP_PKEY_CTX_ctrl now
calls these methods internally to interact with providers).
EVP_PKEY_CTX_gettable_params() and EVP_PKEY_CTX_settable_params() get a
constant B<OSSL_PARAM> array that describes the gettable and
settable parameters for the current algorithm implementation, i.e. parameters
that can be used with EVP_PKEY_CTX_get_params() and EVP_PKEY_CTX_set_params()
respectively.
See L<OSSL_PARAM(3)> for the use of B<OSSL_PARAM> as parameter descriptor.
These functions must only be called after the EVP_PKEY_CTX has been initialised
for use in an operation.

=head1 RETURN VALUES
EVP_PKEY_CTX_set_params() returns 1 for success or 0 otherwise.
EVP_PKEY_CTX_settable_params() returns an OSSL_PARAM array on success or NULL on
error.
It may also return NULL if there are no settable parameters available.
All other functions and macros described on this page return a positive value
for success and 0 or a negative value for failure. In particular a return value
of -2 indicates the operation is not supported by the public key algorithm.

EVP_KEYEXCH-DH
- DH Key Exchange algorithm support
=head1 DESCRIPTION
Key exchange support for the B<DH> key type.
=head2 DH key exchange parameters
=over 4
=item "pad" (B<OSSL_EXCHANGE_PARAM_PAD>) <unsigned integer>
See L<provider-keyexch(7)/Common Key Exchange parameters>.
=back
=head1 EXAMPLES
The examples assume a host and peer both generate keys using the same
named group (or domain parameters). See L<EVP_PKEY-DH(7)/Examples>.
Both the host and peer transfer their public key to each other.
To convert the peer's generated key pair to a public key in DER format in order
to transfer to the host:
EVP_PKEY *peer_key; /* It is assumed this contains the peers generated key */
unsigned char *peer_pub_der = NULL;
int peer_pub_der_len;
peer_pub_der_len = i2d_PUBKEY(peer_key, &peer_pub_der);
...
OPENSSL_free(peer_pub_der);
To convert the received peer's public key from DER format on the host:
const unsigned char *pd = peer_pub_der;
EVP_PKEY *peer_pub_key = d2i_PUBKEY(NULL, &pd, peer_pub_der_len);
...
EVP_PKEY_free(peer_pub_key);
To derive a shared secret on the host using the host's key and the peer's public
key:
/* It is assumed that the host_key and peer_pub_key are set up */
void derive_secret(EVP_KEY *host_key, EVP_PKEY *peer_pub_key)
{
unsigned int pad = 1;
OSSL_PARAM params[2];
unsigned char *secret = NULL;
size_t secret_len = 0;
EVP_PKEY_CTX *dctx = EVP_PKEY_CTX_new_from_pkey(NULL, host_key, NULL);
EVP_PKEY_derive_init(dctx);
/* Optionally set the padding */
params[0] = OSSL_PARAM_construct_uint(OSSL_EXCHANGE_PARAM_PAD, &pad);
params[1] = OSSL_PARAM_construct_end();
EVP_PKEY_CTX_set_params(dctx, params);
EVP_PKEY_derive_set_peer(dctx, peer_pub_key);
/* Get the size by passing NULL as the buffer */
EVP_PKEY_derive(dctx, NULL, &secret_len);
secret = OPENSSL_zalloc(secret_len);
EVP_PKEY_derive(dctx, secret, &secret_len);
...
OPENSSL_clear_free(secret, secret_len);
EVP_PKEY_CTX_free(dctx);
}
Very similar code can be used by the peer to derive the same shared secret
using the host's public key and the peer's generated key pair.

EVP_KEYEXCH-ECDH - ECDH Key Exchange algorithm support
=head1 DESCRIPTION
Key exchange support for the B<ECDH> key type.
=head2 ECDH Key Exchange parameters
=over 4
=item "ecdh-cofactor-mode" (B<OSSL_EXCHANGE_PARAM_EC_ECDH_COFACTOR_MODE>) <integer>
Sets or gets the ECDH mode of operation for the associated key exchange ctx.
In the context of an Elliptic Curve Diffie-Hellman key exchange, this parameter
can be used to select between the plain Diffie-Hellman (DH) or Cofactor
Diffie-Hellman (CDH) variants of the key exchange algorithm.
When setting, the value should be 1, 0 or -1, respectively forcing cofactor mode
on, off, or resetting it to the default for the private key associated with the
given key exchange ctx.
When getting, the value should be either 1 or 0, respectively signaling if the
cofactor mode is on or off.
See also L<provider-keymgmt(7)> for the related
B<OSSL_PKEY_PARAM_USE_COFACTOR_ECDH> parameter that can be set on a
per-key basis.
=item "kdf-type" (B<OSSL_EXCHANGE_PARAM_KDF_TYPE>) <utf8_string>
Sets or gets the Key Derivation Function type to apply within the associated key
exchange ctx.
=item "kdf-digest" (B<OSSL_EXCHANGE_PARAM_KDF_DIGEST>) <utf8_string>
Sets or gets the Digest algorithm to be used as part of the Key Derivation Function
associated with the given key exchange ctx.
=item "kdf-digest-props" (B<OSSL_EXCHANGE_PARAM_KDF_DIGEST_PROPS>) <utf8_string>
Sets properties to be used upon look up of the implementation for the selected
Digest algorithm for the Key Derivation Function associated with the given key
exchange ctx.
=item "kdf-outlen" (B<OSSL_EXCHANGE_PARAM_KDF_OUTLEN>) <size_t>
Sets or gets the desired size for the output of the chosen Key Derivation Function
associated with the given key exchange ctx.
=item "kdf-ukm" (B<OSSL_EXCHANGE_PARAM_KDF_UKM>) <octet_string>
Sets the User Key Material to be used as part of the selected Key Derivation
Function associated with the given key exchange ctx.

=head1 NAME
EVP_PKEY-DH, EVP_KEYMGMT-DH - EVP_PKEY DH keytype and algorithm support
=head1 DESCRIPTION
For B<DH> FFC key agreement, two classes of domain parameters can be used:
"safe" domain parameters that are associated with approved named safe-prime
groups, and a class of "FIPS 186-type" domain parameters. FIPS 186-type domain
parameters should only be used for backward compatibility with existing
applications that cannot be upgraded to use the approved safe-prime groups.
See L<EVP_PKEY-FFC(7)> for more information about FFC keys.
For B<DH> that is not a named group) the FIPS186-4 standard specifies that the
values used for FFC parameter generation are also required for parameter
validation. This means that optional FFC domain parameter values for
I<seed>, I<pcounter> and I<gindex> may need to be stored for validation purposes.
For B<DH> the I<seed> and I<pcounter> can be stored in ASN1 data
(but the I<gindex> is not).
=head2 DH parameters
In addition to the common FCC parameters that all FFC keytypes should support
(see L<EVP_PKEY-FFC(7)/FFC parameters>)) the B<DH> keytype
implementation supports the following:
=over 4
=item "group" (B<OSSL_PKEY_PARAM_DH_GROUP>) <UTF8 string>
Set or gets a string that associates a B<DH> named safe prime group with known
values for I<p>, I<q> and I<g>.
The following values can be used by the OpenSSL's default and FIPS providers:
"ffdhe2048", "ffdhe3072", "ffdhe4096", "ffdhe6144", "ffdhe8192",
"modp_2048", "modp_3072", "modp_4096", "modp_6144", "modp_8192".
The following additional values can also be used by OpenSSL's default provider:
"modp_1536", "dh_1024_160", "dh_2048_224", "dh_2048_256".
DH named groups can be easily validated since the parameters are well known.
For protocols that only transfer I<p> and I<g> the value of I<q> can also be
retrieved.
=item "safeprime-generator" (B<OSSL_PKEY_PARAM_DH_GENERATOR>) <integer>
Used for DH generation of safe primes using the old generator code.
It is recommended to use a named safe prime group instead, if domain parameter
validation is required. The default value is 2.
These are not named safe prime groups so setting this value for the OpenSSL FIPS
provider will instead choose a named safe prime group based on the size of I<p>.
=back
=head2 DH domain parameter / key generation parameters
In addition to the common FCC key generation parameters that all FFC key types
should support (see L<EVP_PKEY-FFC(7)/FFC key generation parameters>)) the
B<DH> keytype implementation supports the following:
=over 4
=item "type" (B<OSSL_PKEY_PARAM_FFC_TYPE>) <utf8_string>
Sets the type of parameter generation. For B<DH> valid values are:
=over 4
=item "fips186_4"
=item "default"
=item "fips186_2"
These are described in L<EVP_PKEY-FFC(7)/FFC key generation parameters>
=item "group"
This specifies that a named safe prime name will be chosen using the "pbits"
type.
=item "generator"
A safe prime generator. See the "safeprime-generator" type above.
=back
=item "pbits" (B<OSSL_PKEY_PARAM_FFC_PBITS>) <unsigned integer>
Sets the size (in bits) of the prime 'p'.
For "fips186_4" this must be 2048.
For "fips186_2" this must be 1024.
For "group" this can be any one of 2048, 3072, 4096, 6144 or 8192.
=item "priv_len" (B<OSSL_PKEY_PARAM_DH_PRIV_LEN>) <integer>
An optional value to set the maximum length of the generated private key.
The default valure used if this is not set is the maximum value of
BN_num_bits(I<q>)). The minimum value that this can be set to is 2 * s.
Where s is the security strength of the key which has values of
112, 128, 152, 176 and 200 for key sizes of 2048, 3072, 4096, 6144 and 8192.
=back
=head1 EXAMPLES
An B<EVP_PKEY> context can be obtained by calling:
EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_from_name(NULL, "DH", NULL);
An B<DH> key can be generated with a named safe prime group by calling:
int priv_len = 2 * 112;
OSSL_PARAM params[3];
EVP_PKEY *pkey = NULL;
EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_from_name(NULL, "DH", NULL);

The B<DSA> and B<DH> keytypes are implemented in OpenSSL's default and FIPS For B<DSA> the FIPS186-4 standard specifies that the values used for FFC
providers. parameter generation are also required for parameter validation.
The implementations support the basic DSA and DH keys, containing the public
and private keys I<pub> and I<priv> as well as the three main domain parameters
I<p>, I<q> and I<g>.
Finite field cryptography (FFC) is a method of implementing discrete logarithm
cryptography using finite field mathematics. DSA is an example of FFC and
Diffie-Hellman key establishment algorithms specified in SP800-56A can also be
implemented as FFC.

=head2 Common DSA & DH parameters
In addition to the common parameters that all keytypes should support (see
L<provider-keymgmt(7)/Common parameters>), the B<DSA> and B<DH> keytype
implementations support the following.
=over 4
=item "pub" (B<OSSL_PKEY_PARAM_PUB_KEY>) <unsigned integer>
The public key value.
=item "priv" (B<OSSL_PKEY_PARAM_PRIV_KEY>) <unsigned integer>
The private key value.

A DSA or Diffie-Hellman prime "p" value.
=item "q" (B<OSSL_PKEY_PARAM_FFC_Q>) <unsigned integer>
A DSA or Diffie-Hellman prime "q" value.
=item "g" (B<OSSL_PKEY_PARAM_FFC_G>) <unsigned integer>
A DSA or Diffie-Hellman generator "g" value.
=item "seed" (B<OSSL_PKEY_PARAM_FFC_SEED>) <octet string>
An optional domain parameter I<seed> value used during generation and validation
of I<p>, I<q> and canonical I<g>.
For validation this needs to set the I<seed> that was produced during generation.
=item "gindex" (B<OSSL_PKEY_PARAM_FFC_GINDEX>) <integer>
Sets the index to use for canonical generation and verification of the generator
I<g>.
Set this to a positive value from 0..FF to use this mode. This I<gindex> can
then be reused during key validation to verify the value of I<g>. If this value
is not set or is -1 then unverifiable generation of the generator I<g> will be
used.
=item "pcounter" (B<OSSL_PKEY_PARAM_FFC_PCOUNTER>) <integer>
An optional domain parameter I<counter> value that is output during generation
of I<p>. This value must be saved if domain parameter validation is required.
=item "hindex" (B<OSSL_PKEY_PARAM_FFC_H>) <integer>
For unverifiable generation of the generator I<g> this value is output during
generation of I<g>. Its value is the first integer larger than one that
satisfies g = h^j mod p (where g != 1 and "j" is the cofactor).

The current standard. This is the default value.
=item "default"
This is an alias to use the latest implemented standard.
It is currently set to "fips186_4".
=item "group"
This specifies that a named safe prime name will be chosen using the "pbits"
type.
=item "fips186_2"
The old standard that should only be used for legacy purposes.
=item "generator"
A safe prime generator. See the "safeprime-generator" type.

described above.
=item "pbits" (B<OSSL_PKEY_PARAM_FFC_PBITS>) <unsigned integer>
Sets the size (in bits) of the prime 'p'.
For "fips186_4" this must be 2048 for DH, and either of 2048 or 3072 for DSA.
For "fips186_2" this must be 1024. For "fips186_2" this must be 1024.

For "fips186_4" or "fips186_2" generation this sets the I<seed> data to use EVP_PKEY_print_params(bio_out, param_key, 0, NULL);
instead of generating a random seed internally. This should be used for
testing purposes only. This will either produce fixed values for the generated
parameters OR it will fail if the seed did not generate valid primes.

=head1 NAME
EVP_PKEY-FFC - EVP_PKEY DSA and DH shared FFC parameters.
=head1 DESCRIPTION
Finite field cryptography (FFC) is a method of implementing discrete logarithm
cryptography using finite field mathematics. DSA is an example of FFC and
Diffie-Hellman key establishment algorithms specified in SP800-56A can also be
implemented as FFC.
The B<DSA> and B<DH> keytypes are implemented in OpenSSL's default and FIPS
providers.
The implementations support the basic DSA and DH keys, containing the public
and private keys I<pub> and I<priv> as well as the three main domain parameters
I<p>, I<q> and I<g>.
For B<DSA> (and B<DH> that is not a named group) the FIPS186-4 standard
specifies that the values used for FFC parameter generation are also required
for parameter validation.
This means that optional FFC domain parameter values for I<seed>, I<pcounter>
and I<gindex> may need to be stored for validation purposes.
For B<DH> the I<seed> and I<pcounter> can be stored in ASN1 data
(but the I<gindex> is not). For B<DSA> however, these fields are not stored in
the ASN1 data so they need to be stored externally if validation is required.
=head2 FFC parameters
In addition to the common parameters that all keytypes should support (see
L<provider-keymgmt(7)/Common parameters>), the B<DSA> and B<DH> keytype
implementations support the following.
=over 4
=item "pub" (B<OSSL_PKEY_PARAM_PUB_KEY>) <unsigned integer>
The public key value.
=item "priv" (B<OSSL_PKEY_PARAM_PRIV_KEY>) <unsigned integer>
The private key value.
=item "p" (B<OSSL_PKEY_PARAM_FFC_P>) <unsigned integer>
A DSA or Diffie-Hellman prime "p" value.
=item "q" (B<OSSL_PKEY_PARAM_FFC_Q>) <unsigned integer>
A DSA or Diffie-Hellman prime "q" value.
=item "g" (B<OSSL_PKEY_PARAM_FFC_G>) <unsigned integer>
A DSA or Diffie-Hellman generator "g" value.
=item "seed" (B<OSSL_PKEY_PARAM_FFC_SEED>) <octet string>
An optional domain parameter I<seed> value used during generation and validation
of I<p>, I<q> and canonical I<g>.
For validation this needs to set the I<seed> that was produced during generation.
=item "gindex" (B<OSSL_PKEY_PARAM_FFC_GINDEX>) <integer>
Sets the index to use for canonical generation and verification of the generator
I<g>.
Set this to a positive value from 0..FF to use this mode. This I<gindex> can
then be reused during key validation to verify the value of I<g>. If this value
is not set or is -1 then unverifiable generation of the generator I<g> will be
used.
=item "pcounter" (B<OSSL_PKEY_PARAM_FFC_PCOUNTER>) <integer>
An optional domain parameter I<counter> value that is output during generation
of I<p>. This value must be saved if domain parameter validation is required.
=item "hindex" (B<OSSL_PKEY_PARAM_FFC_H>) <integer>
For unverifiable generation of the generator I<g> this value is output during
generation of I<g>. Its value is the first integer larger than one that
satisfies g = h^j mod p (where g != 1 and "j" is the cofactor).
=item "j" (B<OSSL_PKEY_PARAM_FFC_COFACTOR>) <unsigned integer>
An optional informational cofactor parameter that should equal to (p - 1) / q.
=back
=head2 FFC key generation parameters
The following key generation types are available for DSA and DH algorithms:
=over 4
=item "type" (B<OSSL_PKEY_PARAM_FFC_TYPE>) <utf8_string>
Sets the type of parameter generation. The shared valid values are:
=over 4
=item "fips186_4"
The current standard. This is the default value.
=item "fips186_2"
The old standard that should only be used for legacy purposes.
=item "default"
This is an alias to use the latest implemented standard.
It is currently set to "fips186_4".
=back
=item "pbits" (B<OSSL_PKEY_PARAM_FFC_PBITS>) <unsigned integer>
Sets the size (in bits) of the prime 'p'.
=item "qbits" (B<OSSL_PKEY_PARAM_FFC_QBITS>) <unsigned integer>
Sets the size (in bits) of the prime 'q'.
For "fips186_4" this can be either 224 or 256.
For "fips186_2" this has a size of 160.
=item "digest" (B<OSSL_PKEY_PARAM_FFC_DIGEST>) <utf8_string>
Sets the Digest algorithm to be used as part of the Key Generation Function
associated with the given Key Generation I<ctx>.
This must also be set for key validation.
=item "properties" (B<OSSL_PKEY_PARAM_FFC_DIGEST_PROPS>) <utf8_string>
Sets properties to be used upon look up of the implementation for the selected
Digest algorithm for the Key Generation Function associated with the given key
generation I<ctx>. This may also be set for key validation.
=item "seed" (B<OSSL_PKEY_PARAM_FFC_SEED>) <octet string>
For "fips186_4" or "fips186_2" generation this sets the I<seed> data to use
instead of generating a random seed internally. This should be used for
testing purposes only. This will either produce fixed values for the generated
parameters OR it will fail if the seed did not generate valid primes.
=item "gindex" (B<OSSL_PKEY_PARAM_FFC_GINDEX>) <integer>
=item "pcounter" (B<OSSL_PKEY_PARAM_FFC_PCOUNTER>) <integer>
=item "hindex" (B<OSSL_PKEY_PARAM_FFC_H>) <integer>
These types are described above.
