问题 I received the two private RSA keys in my mail and I copied and saved it as validator.pem and user.pem which I used to connect to remote server. This is working. Now, I need to convert them to .jks files, but I get the following errors: java.lang.Exception: Input not an X.509 certificate validator.pem -----BEGIN RSA PRIVATE KEY----- -----END RSA PRIVATE KEY----- ---------------------------------------------------------- user.pem -----BEGIN RSA PRIVATE KEY----- -----END RSA PRIVATE KEY-----

问题 Basicly, I have a private PEM key and a public certificate PEM key. They work when I use them both (but don't work if I only use one of them). I use and this works: wget --no-check-certificate --private-key=dev-private.pem --certificate=dev.pem https://???.???.???.??? (This is self-signed certificate signed by java keytool. I have acces to this keystore.) I also produce a jks and it's work great in browser. The problem is one of my application I neeed to use a certificate and he only support

问题 I read the .der file as follows. byte[] byteKey = File.ReadAllBytes(openFileDialog1.FileName); X509Certificate2 cert = new X509Certificate2(byteKey); but it doesn't have private key. It has only public key. cert.HasPrivateKey return false. When I search it, I found that '.der file doesn't have private Key, private Key is in .key file'. I use Notepad ++ to open a .key file in the same path as the .der file, the broken text will be printed. first question, How to read private key from .key file

问题 The following code uses the JcaPEMWriter class from BouncyCastle to output a randomly generated RSA private key in PKCS#1 format ( -----BEGIN RSA PRIVATE KEY----- ): public static void main(String[] args) throws Exception { final KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA"); kpg.initialize(2048, null); final KeyPair kp = kpg.generateKeyPair(); final PrivateKey privateKey = kp.getPrivate(); final StringWriter s = new StringWriter(); try (JcaPEMWriter w = new JcaPEMWriter(s)) { w
