Phar::setSignatureAlgorithm
(PHP >= 5.3.0, PECL phar >= 1.1.0)
Phar::setSignatureAlgorithm — set the signature algorithm for a phar and apply it.
Description
Note:
This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.
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().
Parameters
- 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);
?>
Return Values
No value is returned.
Errors/Exceptions
Throws UnexpectedValueException for many errors, and a PharException if any problems occur flushing changes to disk.
