EccMakeKeys Method

Generate an EC public/private key pair and save as two key files.

Namespace: CryptoSysPKI
Assembly: diCrSysPKINet (in diCrSysPKINet.dll) Version: 23.0.0.30549 (23.1.0.0)
Syntax
Copy
public static int MakeKeys(
	string publicKeyfile,
	string privateKeyFile,
	EccCurveName curveName,
	string password,
	EccPbeScheme pbes = EccPbeScheme.Default,
	string paramString = "",
	EccFormat fileFormat = EccFormat.Default
)

Parameters

publicKeyfile  String
name of public key file to be created
privateKeyFile  String
name of encrypted private key file to be created
curveName  EccCurveName
name of elliptic curve
password  String
password to be used for the encrypted key file.
pbes  EccPbeScheme  (Optional)
(optional) Password-based encryption scheme to encrypt private key [default = pbeWithSHAAnd3-KeyTripleDES-CBC]
paramString  String  (Optional)
Optional parameters. A set of attribute name=value pairs separated by a semicolon ";" (see remarks).
fileFormat  EccFormat  (Optional)
(optional) Format to save file [default = DER binary]

Return Value

Int32
Zero if successful or non-zero error code
Remarks

Valid name-value pairs for paramString are:

count=integerTo set the iteration count used in the PBKDF2 method, e.g. "count=5000;" [default=2048].
prf=hmac-nameTo change the HMAC algorithm used in the PBKDF2 method, e.g. "prf=hmacwithSHA256;" [default=hmacwithSHA1].
rngseed=stringTo add some user-supplied entropy for the key generation process, e.g. "rngseed=pqrrr1234xyz;".
Valid values for hmac-name are {hmacWithSHA1|hmacWithSHA224|hmacWithSHA256|hmacWithSHA384|hmacWithSHA512}.
Example
C#
Copy
// All default settings...
n = Ecc.MakeKeys(pubkeyfile, prikeyfile, Ecc.CurveName.Prime192v1, "password");
// With specialist options...
n = Ecc.MakeKeys(pubkeyfile, prikeyfile, Ecc.CurveName.Prime192v1, "password", 
       Ecc.PbeScheme.Pbe_Pbkdf2_aes128_CBC, "count=3999;prf=hmacWithSha256", Ecc.Format.PEM);
