Rsa.MakeKeys(String, String, String, Int32, Rsa.PublicExponent, Rsa.PbeOptions, String, Rsa.Format, Boolean) Method

Generate an RSA public/private key pair.

Syntax

public static int MakeKeys(
   string publicKeyFile,
   string privateKeyFile,
   string password,
   int bits,
   Rsa.PublicExponent exponent = Rsa.PublicExponent.Exp_EQ_65537,
   Rsa.PbeOptions pbes = Rsa.PbeOptions.Default,
   string paramString = "",
   Rsa.Format fileFormat = Rsa.Format.Default,
   bool showProgress = false 
)

Public Shared Function MakeKeys (
   publicKeyFile As String,
   privateKeyFile As String,
   password As String,
   bits As Integer,
   Optional exponent As Rsa.PublicExponent = Rsa.PublicExponent.Exp_EQ_65537,
   Optional pbes As Rsa.PbeOptions = Rsa.PbeOptions.Default,
   Optional paramString As String = "",
   Optional fileFormat As Rsa.Format = Rsa.Format.Default,
   Optional showProgress As Boolean = false 
) As Integer

Parameters

publicKeyFile  String

Output filename for public key

privateKeyFile  String

Output filename for (encrypted) private key

password  String

Password for encrypted private key

bits  Int32

Required key modulus size in bits (min 96)

exponent  Rsa.PublicExponent  (Optional)

Exponent [default=65537=F4]

pbes  Rsa.PbeOptions  (Optional)

Encryption scheme to encrypt private key [default=pbeWithSHAAnd3-KeyTripleDES-CBC from PKCS#12]

paramString  String  (Optional)

Optional parameters. A set of attribute name=value pairs separated by a semicolon ";" (see remarks)

fileFormat  Rsa.Format  (Optional)

Format to save file [default = DER binary]

showProgress  Boolean  (Optional)

Indicate progress in console

Return Value

Remarks

Example

string pubkeyFile = "carol_pub.pem.txt";
string prikeyFile = "carol_epk.pem.txt";
int n = Rsa.MakeKeys(pubkeyFile, prikeyFile, "strong-password!", 2048, Rsa.PublicExponent.Exp_EQ_65537,
Rsa.PbeOptions.Pbe_Pbkdf2_aes128_CBC, "count=3000;prf=hmacWithSHA256", Rsa.Format.PEM, true);
Console.WriteLine("Rsa.MakeKeys returned {0}", n);
Debug.Assert(n == 0, "Failed to create RSA key pair");
Console.WriteLine("Created public/private key pair OK");
