php中mcrypt_encrypt升级到openssl_encrypt

php中mcrypt_encrypt升级到openssl_encrypt

原因: php8中已经弃用 mcrypt_encrypt

详细测试代码

$account= [
    'encodeKey' => '0f5264038205EDFB1AC05fbb0e8c5e94',
    'ivKey' => '0f5264038205EDFB',
    'password' => 'testpwd',  //登陆密码
];


// 历史代码, 使用mcrypt_encrypt加密数据
echo $encrypted = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $account['encodeKey'], $account['password'], MCRYPT_MODE_CBC, $account['ivKey']));
echo '
';


// error:0607F08A:digital envelope routines:EVP_EncryptFinal_ex:data not multiple of block length
// 要加密的数据长度不是密钥长度的倍数
$pwd = $account['password'];
while (strlen($pwd)%16 != 0){
    $pwd = $pwd."\x0";
}

// 使用openssl_encrypt加密base64编码后的数据
$encrypted_openssl = openssl_encrypt($pwd, 'AES-256-CBC', $account['encodeKey'], OPENSSL_ZERO_PADDING, $account['ivKey']);


// var_dump('error: '.openssl_error_string());
echo $encrypted_openssl;
