Phar::setSignatureAlgorithm
(PHP >= 5.3.0, PECL phar >= 1.1.0)
Phar::setSignatureAlgorithm — set the signature algorithm for a phar and apply it.
说明
$sigtype
[, string $privatekey
] )Note:
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:
See phar introduction for instructions on naming and placement of the public key file.<?php
$private = openssl_get_privatekey ( file_get_contents ( 'private.pem' ));
$pkey = '' ;
openssl_pkey_export ( $private , $pkey );
$p -> setSignatureAlgorithm ( Phar :: OPENSSL , $pkey );
?>
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.
