Question

problem generating pgp keys?

Answer 1

+3 A:

RSA and PGP are different.

What you are essentially asking is how do I run my petrol car on diesel? The answer is you can't.

You should look into PGP CommandLine - this allows you to perform PGP commands from the command line.

A:

hi ck, thnx for the reply. the thing is in the pgp desktop in key setting i ve seen internally it is using rsa so i thought to pass keys generated by rsa for encryption and decryption in pgp. but everything went for a toss. k can you please tell me how to generate pgp keys using c#

You should put this in a reply to his answer, not in a separate answer.

Answer 3

+1 A:

using the bouncycastle c# library this is how i generate key pairs.



public void GenerateKey(string username, string password, string keyStoreUrl)
        {
            IAsymmetricCipherKeyPairGenerator kpg = new RsaKeyPairGenerator();
            kpg.Init(new RsaKeyGenerationParameters(BigInteger.ValueOf(0x13), new SecureRandom(), 1024, 8));
            AsymmetricCipherKeyPair kp = kpg.GenerateKeyPair();

            FileStream out1 = new FileInfo(string.Format("{0}secret.asc", keyStoreUrl)).OpenWrite();
            FileStream out2 = new FileInfo(string.Format("{0}pub.asc", keyStoreUrl)).OpenWrite();

            ExportKeyPair(out1, out2, kp.Public, kp.Private, username, password.ToCharArray(), true);

        }

private static void ExportKeyPair(
            Stream secretOut,
            Stream publicOut,
            AsymmetricKeyParameter publicKey,
            AsymmetricKeyParameter privateKey,
            string identity,
            char[] passPhrase,
            bool armor)
        {
            if (armor)
            {
                secretOut = new ArmoredOutputStream(secretOut);
            }

            PgpSecretKey secretKey = new PgpSecretKey(
                PgpSignature.DefaultCertification,
                PublicKeyAlgorithmTag.RsaGeneral,
                publicKey,
                privateKey,
                DateTime.Now,
                identity,
                SymmetricKeyAlgorithmTag.Cast5,
                passPhrase,
                null,
                null,
                new SecureRandom()
                //                ,"BC"
                );

            secretKey.Encode(secretOut);

            secretOut.Close();

            if (armor)
            {
                publicOut = new ArmoredOutputStream(publicOut);
            }

            PgpPublicKey key = secretKey.PublicKey;

            key.Encode(publicOut);

            publicOut.Close();
        }

and it generate private and public keys in armored ASCII format such as.

Answer 4

A:

Hi, thanks for the good methods, was faffing around the web for them since quite a while,

some correction tho...

After a call to

ExportKeyPair(out1, out2, kp.Public, kp.Private, username, password.ToCharArray(), true);

please also call

out1.Close();
out2.Close();

A sample private key generated from the above routine

thanks once again for the above methods.
