Generates a new private key (PHP 4 >= 4.2.0, PHP 5)
resource openssl_pkey_new ( [array configargs] )

openssl_pkey_new() generates a new private and public key pair. The public component of the key can be obtained using openssl_pkey_get_public().


You need to have a valid openssl.cnf installed for this function to operate correctly. See the notes under the installation section for more information.



You can finetune the key generation (such as specifying the number of bits) using configargs. See openssl_csr_new() for more information about configargs.

Return Values

Returns a resource identifier for the pkey on success, or FALSE on error.
