=pod =head1 NAME EVP_PKEY_new, EVP_PKEY_free - private key allocation functions. =head1 SYNOPSIS #include <openssl/evp.h> EVP_PKEY *EVP_PKEY_new(void); void EVP_PKEY_free(EVP_PKEY *key); =head1 DESCRIPTION The EVP_PKEY_new() function allocates an empty B<EVP_PKEY> structure which is used by OpenSSL to store private keys. EVP_PKEY_free() frees up the private key B<key>. =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)|EVP_PKEY_set1_RSA(3)> should be used. =head1 RETURN VALUES EVP_PKEY_new() returns either the newly allocated B<EVP_PKEY> structure of B<NULL> if an error occurred. EVP_PKEY_free() does not return a value. =head1 SEE ALSO L<EVP_PKEY_set1_RSA(3)|EVP_PKEY_set1_RSA(3)> =head1 HISTORY TBA =cut
