Phar::setSignatureAlgorithm

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.1.0)

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

说明

public Phar::setSignatureAlgorithm ( int $sigtype , string $privatekey = ? ) : void

注意:

此方法需要 将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.

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().

参数

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.

返回值

没有返回值。

错误／异常

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