Is there any Cryptographic function which would simulate openssl_sign($data, $signature, $pkeyid); in ASP.NET?
I have a private key which is generated with OpenSSL application (http://www.slproweb.com/products/Win32OpenSSL.html) in .pem format and I need to sign piece of string with that private key, but
I can't get any info, so, please help..
First of all thanks a LOT. Obviously this is the way to go but I can't use the command to generate the pkcs12.
When I try to run that it just tells me the various options, do you have any suggestions? ;)
On what step do you run into the problem?
If it's on step 3, you just need to enter your company details (or you can even left those fields blank):
If it's on step 4, you just need to enter the password and repeat it after that (but keep in mind that you will not see it on the screen as you type it):
Aha! :9 I tried to run "openssl.exe pkcs12 -export ...." as it turns out you start openssl and then supply the commands. Thanks for clearing things up!

I got a solution, so if anyone ever will be in a same situation, here is a procedure:
public string CreateSignature(string signatureString) { SHA1CryptoServiceProvider sha1 = new SHA1CryptoServiceProvider(); X509Certificate2 cert = new X509Certificate2(MapPath("~/App_Data/P12File.p12"), "password"); RSACryptoServiceProvider rsaCryptoIPT = (RSACryptoServiceProvider)cert.PrivateKey; ASCIIEncoding encoder = new ASCIIEncoding(); byte[] binData = encoder.GetBytes(signatureString); byte[] binSignature = rsaCryptoIPT.SignData(binData, sha1); return Convert.ToBase64String(binSignature); }CatZ

I tried this is MVC2 application
X509Certificate2 cert = new X509Certificate2(MapPath("~/App_Data/P12File.p12"), "" );
causes compile error
The name 'MapPath' does not exist in the current context
X509Certificate2 cert = new X509Certificate2(HttpContext.Current.Server.MapPath("~/App_Data/P12File.p12"), "" );
causes compile error
The name 'HttpContext' does not exist in the current context
How to use this method in MVC2 application controller ?

Hi Kipo ,
Can you please tell me what we we need to pass as "signatureString" parameter in the "CreateSignature" function?
Thanks,
Kusum
