SigSignData Method

Compute a signature value over data in a byte array.

Namespace: CryptoSysPKI
Assembly: diCrSysPKINet (in diCrSysPKINet.dll) Version: 23.0.0.25611 (23.0.0.0)
Syntax
Copy
public static string SignData(
	byte[] data,
	string privateKeyFile,
	string password,
	SigAlgorithm sigAlg,
	SigSigOptions sigOpts = SigSigOptions.Default,
	SigEncoding sigEncoding = SigEncoding.Default
)

Parameters

data  Byte
input data to be signed
privateKeyFile  String
Name of private key file (or a string containing the key in PEM format, or an internal private key)
password  String
Password for the private key, if encrypted
sigAlg  SigAlgorithm
Signature algorithm to be used
sigOpts  SigSigOptions  (Optional)
(optional) Options for ECDSA and RSA-PSS signatures
sigEncoding  SigEncoding  (Optional)
Optional encodings for output [default=base64]

Return Value

String
The encoded signature, or an empty string on error
Example
C#
Copy
string keyFile = "AlicePrivRSASign.p8e";    // Used to sign data
string password = "password";
// Input to be signed: a byte array with ASCII string "abc"
byte[] b = System.Text.Encoding.Default.GetBytes("abc");
string sig = Sig.SignData(b, keyFile, password, SigAlgorithm.Default);
Console.WriteLine("Sig.SignData returns \n'" + sig + "'");
