我有此代码来创建RSA 4096公钥和私钥来加密和解密字符串。
代码:
<?php
$config = array(
"config" => "C:/xampp/php/extras/openssl/openssl.cnf",
"private_key_bits" => 4096,
"private_key_type" => OPENSSL_KEYTYPE_RSA
);
// Create the private and public key
$res = openssl_pkey_new($config);
// Extract the private key from $res to $privKey
openssl_pkey_export($res, $privKey);
// Extract the public key from $res to $pubKey
$pubKey = openssl_pkey_get_details($res);
$pubKey = $pubKey["key"];
$data = 'Hello, World!';
// Encrypt the data to $encrypted using the public key
openssl_public_encrypt($data, $encrypted, $pubKey);
echo $encrypted;
// Decrypt the data using the private key and store the results in $decrypted
openssl_private_decrypt($encrypted, $decrypted, $privKey);
echo $decrypted;
?>
它创建密钥,加密data
字符串(Hello, World!
),但是当尝试解密encrypted
字符串时,发生错误:
警告:openssl_private_decrypt():密钥参数不是26:>行上的C:\ xampp \ htdocs \ rsa \ index.php中的有效私钥。
我有此代码来创建RSA 4096公钥和私钥以加密和解密字符串。代码:“ C:/xampp/php/extras/openssl/openssl.cnf”,“ ...
好,这对我有用:
将openssl_pkey_export($res, $privKey);
更改为openssl_pkey_export($res, $privKey, NULL, $config);
。
您不需要像这样导出私钥,至少直到将其保存到安全的地方:
