I am trying to generate a self-signed certificate with OpenSSL with SubjectAltName in it.While I am generating the csr for the certificate, my guess is I have to use v3 extensions of OpenSSL x509.

Its a three step process, and it involves modifying openssl.cnf file. You might be able to do it with only command line options, but I don't do it that way. Find your openssl.cnf file. It is likely located in /usr/lib/ssl

问题 I need to create an Https connection with a remote server then retrieve and verify the certificate. I have established the connection fine: try { url = new URL(this.SERVER_URL); HttpURLConnection con = (HttpURLConnection) url.openConnection(); HttpsURLConnection secured = (HttpsURLConnection) con; secured.connect(); } But it seems getServerCertificateChain() method is undefined by the type HttpsURLConnection . So how do I retrieve the server certificate chain? My understanding is that

Httplistener with HTTPS support

阅读更多关于 Httplistener with HTTPS support

There seems to be a lot of confusing, sometimes conflicting, information with regards to making a .NET HTTPListener HTTPS capable. My understanding is as follows: One's C# code needs an https prefix (for example, https://*:8443 ) in order for the listener to understand that it needs to service SSL requests at this port. The actual SSL handshake happens under the covers and is handled by http.sys (buried somewhere on the Windows machine). The C# code doesn't have to explicitly manage the SSL handshake, because it happens under the covers. One needs to have a "X.509 trusted certificate" on the

阅读更多关于 Creating an X509 Certificate in Java without BouncyCastle?

问题 Is it possible to sanely create an X509 Certificate in Java code without using the Bouncy Castle X509V*CertificateGenerator classes? 回答1: The ability to sign certificates is not part of a standard Java library or extension. A lot of the code that is needed to do it yourself is part of the core. There are classes to encode and decode X.500 names, X.509 certificate extensions, public keys for various algorithms, and of course, for actually performing the digital signature. Implementing this
