=head1 DESCRIPTION
|
|
|
|
The EVP_PKEY_new() function allocates an empty B<EVP_PKEY> structure which is
|
|
used by OpenSSL to store private keys. The reference count is set to B<1>.
|
|
|
|
EVP_PKEY_up_ref() increments the reference count of B<key>.
|
|
|
|
EVP_PKEY_free() decrements the reference count of B<key> and, if the reference
|
|
count is zero, frees it up. If B<key> is NULL, nothing is done.
|
|
|
|
EVP_PKEY_new_raw_private_key() allocates a new B<EVP_PKEY>. If B<e> is non-NULL
|
|
then the new B<EVP_PKEY> structure is associated with the engine B<e>. The
|
|
B<type> argument indicates what kind of key this is. The value should be a NID
|
|
for a public key algorithm that supports raw private keys, i.e. one of
|
|
B<EVP_PKEY_HMAC>, B<EVP_PKEY_POLY1305>, B<EVP_PKEY_SIPHASH>, B<EVP_PKEY_X25519>,
|
|
B<EVP_PKEY_ED25519>, B<EVP_PKEY_X448> or B<EVP_PKEY_ED448>. B<key> points to the
|
|
raw private key data for this B<EVP_PKEY> which should be of length B<keylen>.
|
|
The length should be appropriate for the type of the key. The public key data
|
|
will be automatically derived from the given private key data (if appropriate
|
|
for the algorithm type).
|
|
|
|
EVP_PKEY_new_raw_public_key() works in the same way as
|
|
EVP_PKEY_new_raw_private_key() except that B<key> points to the raw public key
|
|
data. The B<EVP_PKEY> structure will be initialised without any private key
|
|
information. Algorithm types that support raw public keys are
|
|
B<EVP_PKEY_X25519>, B<EVP_PKEY_ED25519>, B<EVP_PKEY_X448> or B<EVP_PKEY_ED448>.
|
|
|
|
EVP_PKEY_new_CMAC_key() works in the same way as EVP_PKEY_new_raw_private_key()
|
|
except it is only for the B<EVP_PKEY_CMAC> algorithm type. In addition to the
|
|
raw private key data, it also takes a cipher algorithm to be used during
|
|
creation of a CMAC in the B<cipher> argument.
|
|
|
|
EVP_PKEY_new_mac_key() works in the same way as EVP_PKEY_new_raw_private_key().
|
|
New applications should use EVP_PKEY_new_raw_private_key() instead.
|
|
|
|
=head1 NOTES
|
|
|
|
The B<EVP_PKEY> structure is used by various OpenSSL functions which require a
|
|
general private key without reference to any particular algorithm.
|
|
|
|
The structure returned by EVP_PKEY_new() is empty. To add a private key to this
|
|
empty structure the functions described in L<EVP_PKEY_set1_RSA(3)> should be
|
|
used.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
EVP_PKEY_new(), EVP_PKEY_new_raw_private_key(), EVP_PKEY_new_raw_public_key(),
|
|
EVP_PKEY_new_CMAC_key() and EVP_PKEY_new_mac_key() return either the newly
|
|
allocated B<EVP_PKEY> structure or B<NULL> if an error occurred.
|
|
|
|
EVP_PKEY_up_ref() returns 1 for success and 0 for failure.

=head1 HISTORY
|
|
|
|
EVP_PKEY_new() and EVP_PKEY_free() exist in all versions of OpenSSL.
|
|
|
|
EVP_PKEY_up_ref() was first added to OpenSSL 1.1.0.
|
|
EVP_PKEY_new_raw_private_key(), EVP_PKEY_new_raw_public_key() and
|
|
EVP_PKEY_new_CMAC_key() were first added to OpenSSL 1.1.1.
