负载产生的OpenSSL Android中/ Java的RSA密钥？ [英] Load RSA key in Android/Java generated with OpenSSL?

问题描述

我已经生成与PHP（OpenSSL的）RSA密钥。它workes罚款。我用这个PHP脚本来创建密钥：

  $配置=阵列（
digest_alg=＆GT; SHA512
private_key_bits=＆GT; 2048，
private_key_type=＆GT; OPENSSL_KEYTYPE_RSA，
 ）;
$键= openssl_pkey_new（$配置）;
$ privateKey = openssl_pkey_get_private（$键）;
$细节= openssl_pkey_get_details（$ privateKey）;
$公钥= $细节['关键'];
openssl_pkey_export_to_file（$ privateKey，'private.pem'）;
的file_put_contents（'public.der'，$公钥）;
 

现在我想的Andr​​oid / Java的加载项（public.der和private.pem）。但我不知道该怎么RSA密钥的格式，因为。我觉得public.der可以在（Android中）资产的文件夹。

我不会存储属于同一设备上的私钥的公钥。

编辑：的public.der文件的内容：

  ----- BEGIN PUBLIC KEY -----

I have generated a RSA key with PHP (openssl). It workes fine. I used this PHP script to create the keys:

$config = array(
"digest_alg" => "sha512",
"private_key_bits" => 2048,
"private_key_type" => OPENSSL_KEYTYPE_RSA,
 );
$keys = openssl_pkey_new($config);
$privateKey = openssl_pkey_get_private($keys);
$details = openssl_pkey_get_details($privateKey);
$publicKey = $details['key'];
openssl_pkey_export_to_file($privateKey, 'private.pem');
file_put_contents('public.der', $publicKey);

Now I would like to load the keys (public.der and private.pem) by Android/Java. But I do not know how because of the format of the RSA key. I think the public.der can be in the assets folder (in Android).

I will not store the public key which belongs to the private key on the same device.

Edit: The content of the public.der file:

-----BEGIN PUBLIC KEY-----

解决方案

Question "load RSA public Key From File" has a detailed answer to the question how to load DER-encoded keys into Java application.

And question "Getting RSA private key from PEM BASE64 Encoded private key file" describes loading PEM-encoded public key into Java application.
