Re: question about exponent, key length and all other RSA parameters not configurable

hi jeffrey, i was wondering if there was a way to import my private key into my application to use to decrypt without exposing it? Can I use the methods provided in the link you provided? Can I use key containers? Do you have any experience with this? On Sun, May 23, 2010 at 8:22 PM, Jeffrey Walto

OpenSSL is closer to Java than C# or Crypto++. So where you see Java, thisnk OpenSSL. Cryptographic Interoperability: Keys http://www.codeproject.com/KB/security/CryptoInteropKeys.aspx Cryptographic Interoperability: Digital Signatures http://www.codeproject.com/KB/security/CryptoInteropSign.aspx

Hi, I'm a newbie when it comes to RSA, the last time I learned it was in school over 7 years ago in one lecture. Maybe I'm missing something but I will try to explain my problem again. A former co worker generated a public and private key for our group. (I think he used PGP but not sure). So I hav

Hi, I'm trying to get the same result with the c# RSACryptoServiceProvider class that 'openssl.exe rsautl ' gives me. The c# class wants more properties set before you can encrypt a message. How can I obtain the parameters that 'openssl.exe rsautl' implements. For example the exponent, q
