openssl_private_decrypt()函数用于使用私钥解密数据。
openssl_private_decrypt()函数将使用私钥解密数据。
使用函数openssl_private_decrypt()将解密使用openssl_private_encrypt()加密的数据。
openssl_private_decrypt ( string $data , string &$decrypted , mixed $key [, int $padding = OPENSSL_PKCS1_PADDING ] ) : bool
序号 | 参数 | 描述 |
---|---|---|
1 | data | 要解密的数据。 |
2 | decrypted | 它将具有解密的数据。 |
3 | key | 私钥。 |
4 | padding | 您可以应用的填充为:OPENSSL_PKCS1_PADDING,OPENSSL_SSLV23_PADDING,OPENSSL_PKCS1_OAEP_PADDING,OPENSSL_NO_PADDING .. |
PHP openssl_private_encrypt()函数成功时返回TRUE,失败时返回FALSE。
此函数将从大于5.0.0的PHP版本开始工作。
要使用openssl_public_encrypt()加密数据并使用openssl_private_decrypt()解密:
<?php //保存私钥 $privkey = openssl_pkey_new(); openssl_pkey_export_to_file($privkey, 'C:/xampp/htdocs/modules/openssl/privatekey.pem'); //保存公钥 $dn = array( "countryName" => "IN", "stateOrProvinceName" => "Karnataka", "localityName" => "test1", "organizationName" => "test2", "organizationalUnitName" => "test3", "commonName" => "www.test.com", "emailAddress" => "xyz@test.com" ); $cert = openssl_csr_new($dn, $privkey); $cert = openssl_csr_sign($cert, null, $privkey, 365); openssl_x509_export_to_file($cert, 'C:/xampp/htdocs/modules/openssl/publickey.pem'); //加密数据 $data = 'Welcome To (cainiaojc.com)'; $isvalid = openssl_public_encrypt ($data, $crypted , file_get_contents('C:/xampp/htdocs/modules/openssl/publickey.pem'),OPENSSL_PKCS1_PADDING); echo "Data encryption : ".$crypted; echo ">br/<>br/<"; if ($isvalid) { openssl_private_decrypt ($crypted, $decrypted , file_get_contents('C:/xampp/htdocs/modules/openssl/privatekey.pem'),OPENSSL_PKCS1_PADDING); echo "Data decryption : ".$decrypted; } ?>
这将产生以下结果:

要使用openssl_public_encrypt()加密文件内容并使用openssl_private_decrypt()解密:
<?php //保存私钥 $privkey = openssl_pkey_new(); openssl_pkey_export_to_file($privkey, 'C:/xampp/htdocs/modules/openssl/privatekey.pem'); //保存公钥 $dn = array( "countryName" => "IN", "stateOrProvinceName" => "Karnataka", "localityName" => "test1", "organizationName" => "test2", "organizationalUnitName" => "test3", "commonName" => "www.test.com", "emailAddress" => "xyz@test.com" ); $cert = openssl_csr_new($dn, $privkey); $cert = openssl_csr_sign($cert, null, $privkey, 365); openssl_x509_export_to_file($cert, 'C:/xampp/htdocs/modules/openssl/publickey.pem'); // 加密数据 $data = file_get_contents('C:/xampp/htdocs/modules/openssl/test.txt'); // save any data in file test.txt; $isvalid = openssl_public_encrypt ($data, $crypted , file_get_contents('C:/xampp/htdocs/modules/openssl/publickey.pem'),OPENSSL_PKCS1_PADDING); echo "Data encryption : ".$crypted; echo ">br/<>br/<"; if ($isvalid) { openssl_private_decrypt ($crypted, $decrypted , file_get_contents('C:/xampp/htdocs/modules/openssl/privatekey.pem'),OPENSSL_PKCS1_PADDING); echo "Data decryption : ".$decrypted; } ?>
这将产生以下结果:
