# openssl_pkey_export

(PHP 4 >= 4.2.0, PHP 5)

openssl_pkey_export -- Gets an exportable representation of a key into a string

## Description

bool openssl_pkey_export ( mixed key, string &out [, string passphrase [, array configargs]])

openssl_pkey_export() exports key as a PEM encoded string and stores it into out (which is passed by reference). The key is optionally protected by passphrase. configargs can be used to fine-tune the export process by specifying and/or overriding options for the openssl configuration file. See openssl_csr_new() for more information about configargs. 成功回傳`TRUE`失敗回傳`FALSE`。

> 備注: 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.
