x509certificate

Microsoft seems to have created a certification jungle, that is hard to understand. Microsoft X.509 certificate (.cer) Personal Information Exchange (.pfx) Assembly Signature Key Attribute (.snk) Would it be advisable to create an snk file based on pfx or cer? (Not sure if its even possible, and if its possible how is it done?) While an assembly can be signed with a password protected pfx, it doesn't seem to be strong named though, unless it is signed with snk instead. But the snk has no password protection. Which one is safer to use? As I am the only developer in my project, I don't have the

I want to retrieve the Key usage value from the X509 structured certificate , i tried the following code X509* lcert=NULL; lCert=PEM_read(filename); // function will return the certificate in X509 unsigned long lKeyusage= lCert->ex_kusage; When i print the lKeyusage value .. some times i get 128 ... sometimes i get 0 for the same certificate .. Can any one tell me what is the error .? If i am doing wrong please give me some sample code or Correct API .. I think the easiest way is to use a memory BIO: ... X509 *lcert = NULL; BUF_MEM *bptr = NULL; char *buf = NULL; int loc; FILE *f = fopen("your

I am trying to sign an Object in a Java + JSF project. What I have done so far is create my own X509 certificate as well as a CA with XCA and install both of them on Firefox and Chrome. I have been searching for 3 days how could I access it to sign (the typical pop-up asking for select a certificate in case you have more than one installed) but I just cannot find something useful. I have seen multiple times this code line: X509Certificate[] certs = (X509Certificate[]) request.getAttribute("javax.servlet.request.X509Certificate"); but I have no clue about where can I get that request with the

Is there any way to combine a certificate and a key (both received separately as Base64 strings from a service) into a .pfx file using C#/.NET Standard programmatically ? Using a tool is not an option, since I need to automate it. The context: I need to load a certificate and a private key (separate Base64 strings without headers and footers) to a X509Certificate2 object to pass it on to the app from a .NET Standard 1.6 library. The problem is, there is no PrivateKey property in the X509Certificate2 class in .NET Standard! So the only way for me to actually load the private key in a
