# Phar::setSignatureAlgorithm

(PHP >= 5.3.0, PECL phar >= 1.1.0)

Phar::setSignatureAlgorithm — set the signature algorithm for a phar and apply it.

### Descrição

void Phar::setSignatureAlgorithm ( int `$sigtype` [, string `$privatekey` ] )

> Nota: Esta função requer a configuração do arquivo php.ini phar.readonly ser definida como 0 para funcionar os objetos Phar. Caso contrário, uma PharException será disparada.

set the signature algorithm for a phar and apply it. The signature algorithm must be one of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL.

Note that all executable phar archives have a signature created automatically, SHA1 by default. data tar- or zip-based archives (archives created with the PharData class) must have their signature created and set explicitly via Phar::setSignatureAlgorithm().

### Parâmetros

`sigtype`

  One of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL

`privatekey`

  The contents of an OpenSSL private key, as extracted from a certificate or OpenSSL key file:

  `<?php
  $private = openssl_get_privatekey(file_get_contents('private.pem'));
  $pkey = '';
  openssl_pkey_export($private, $pkey);
  $p->setSignatureAlgorithm(Phar::OPENSSL, $pkey);
  ?>`
  See phar introduction for instructions on naming and placement of the public key file.

### Valor Retornado

Não há valor retornado.

### Erros

Throws UnexpectedValueException for many errors, and a PharException if any problems occur flushing changes to disk.
