Phar::setSignatureAlgorithm()

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

Set the signature algorithm for a phar and apply it

说明

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

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 ofPhar::MD5,Phar::SHA1,Phar::SHA256,Phar::SHA512, orPhar::OPENSSL.

Note that all executable phar archives have a signature created automatically,SHA1by 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 ofPhar::MD5,Phar::SHA1,Phar::SHA256,Phar::SHA512, orPhar::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.
