.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "EVP_PKEY_NEW 3"
way too many mistakes in technical documents.
\fBEVP_PKEY_up_ref() increments the reference count of key.
\fBEVP_PKEY_free() decrements the reference count of key and, if the reference count is zero, frees it up. If key is \s-1NULL,\s0 nothing is done.
\fBEVP_PKEY_new_raw_private_key() allocates a new \s-1EVP_PKEY\s0. If e is non-NULL then the new \s-1EVP_PKEY\s0 structure is associated with the engine e. The \fBtype argument indicates what kind of key this is. The value should be a \s-1NID\s0 for a public key algorithm that supports raw private keys, i.e. one of \fB\s-1EVP_PKEY_HMAC\s0, \s-1EVP_PKEY_POLY1305\s0, \s-1EVP_PKEY_SIPHASH\s0, \s-1EVP_PKEY_X25519\s0, \fB\s-1EVP_PKEY_ED25519\s0, \s-1EVP_PKEY_X448\s0 or \s-1EVP_PKEY_ED448\s0. key points to the raw private key data for this \s-1EVP_PKEY\s0 which should be of length 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).
\fBEVP_PKEY_new_raw_public_key() works in the same way as \fBEVP_PKEY_new_raw_private_key() except that key points to the raw public key data. The \s-1EVP_PKEY\s0 structure will be initialised without any private key information. Algorithm types that support raw public keys are \fB\s-1EVP_PKEY_X25519\s0, \s-1EVP_PKEY_ED25519\s0, \s-1EVP_PKEY_X448\s0 or \s-1EVP_PKEY_ED448\s0.
\fBEVP_PKEY_new_CMAC_key() works in the same way as EVP_PKEY_new_raw_private_key() except it is only for the \s-1EVP_PKEY_CMAC\s0 algorithm type. In addition to the raw private key data, it also takes a cipher algorithm to be used during creation of a \s-1CMAC\s0 in the cipher argument. The cipher should be a standard encryption only cipher. For example \s-1AEAD\s0 and \s-1XTS\s0 ciphers should not be used.
\fBEVP_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.
\fBEVP_PKEY_get_raw_private_key() fills the buffer provided by priv with raw private key data. The size of the priv buffer should be in *len on entry to the function, and on exit *len is updated with the number of bytes actually written. If the buffer priv is \s-1NULL\s0 then *len is populated with the number of bytes required to hold the key. The calling application is responsible for ensuring that the buffer is large enough to receive the private key data. This function only works for algorithms that support raw private keys. Currently this is: \s-1EVP_PKEY_HMAC\s0, \s-1EVP_PKEY_POLY1305\s0, \s-1EVP_PKEY_SIPHASH\s0, \fB\s-1EVP_PKEY_X25519\s0, \s-1EVP_PKEY_ED25519\s0, \s-1EVP_PKEY_X448\s0 or \s-1EVP_PKEY_ED448\s0.
\fBEVP_PKEY_get_raw_public_key() fills the buffer provided by pub with raw public key data. The size of the pub buffer should be in *len on entry to the function, and on exit *len is updated with the number of bytes actually written. If the buffer pub is \s-1NULL\s0 then *len is populated with the number of bytes required to hold the key. The calling application is responsible for ensuring that the buffer is large enough to receive the public key data. This function only works for algorithms that support raw public keys. Currently this is: \s-1EVP_PKEY_X25519\s0, \s-1EVP_PKEY_ED25519\s0, \s-1EVP_PKEY_X448\s0 or \fB\s-1EVP_PKEY_ED448\s0.
The structure returned by EVP_PKEY_new() is empty. To add a private or public key to this empty structure use the appropriate functions described in \fBEVP_PKEY_set1_RSA\|(3), EVP_PKEY_set1_DSA, EVP_PKEY_set1_DH or EVP_PKEY_set1_EC_KEY.
\fBEVP_PKEY_up_ref(), EVP_PKEY_get_raw_private_key() and \fBEVP_PKEY_get_raw_public_key() return 1 for success and 0 for failure.
The EVP_PKEY_up_ref() function was added in OpenSSL 1.1.0.
The \fBEVP_PKEY_new_raw_private_key(), EVP_PKEY_new_raw_public_key(), \fBEVP_PKEY_new_CMAC_key(), EVP_PKEY_new_raw_private_key() and \fBEVP_PKEY_get_raw_public_key() functions were added in OpenSSL 1.1.1.
