# openssl_pkey_export_to_file

(PHP 4 >= 4.2.0, PHP 5)

openssl_pkey_export_to_file -- Gets an exportable representation of a key into a file

## Description

bool openssl_pkey_export_to_file ( mixed key, string outfilename [, string passphrase [, array configargs]] )

openssl_pkey_export_to_file() saves an ascii-armoured (PEM encoded) rendition of `key` into the file named by `outfilename`. The key can be optionally protected by a `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`. Retorna `TRUE` em caso de sucesso ou `FALSE` em falhas.

> Nota: 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.
