| EVP_PKEY_new, EVP_PKEY_free - private key allocation functions. |
| EVP_PKEY *EVP_PKEY_new(void); |
| void EVP_PKEY_free(EVP_PKEY *key); |
| 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>. |
| The B<EVP_PKEY> structure is used by various OpenSSL functions |
| which require a general private key without reference to any |
| 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. |
| 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. |
