OpenPGP clear signs a file.

Namespace: DidiSoft.Pgp
Assembly: DidiSoft.Pgp (in DidiSoft.Pgp.dll) Version: 1.7.3.35547

Syntax

C#
public void ClearSignFile(
	FileInfo inputFile,
	FileInfo privateKeyFile,
	string privateKeyPassword,
	HashAlgorithm hashingAlgorithm,
	FileInfo outputFile
)
Visual Basic
Public Sub ClearSignFile ( _
	inputFile As FileInfo, _
	privateKeyFile As FileInfo, _
	privateKeyPassword As String, _
	hashingAlgorithm As HashAlgorithm, _
	outputFile As FileInfo _
)
Visual C++
public:
void ClearSignFile(
	FileInfo^ inputFile, 
	FileInfo^ privateKeyFile, 
	String^ privateKeyPassword, 
	HashAlgorithm hashingAlgorithm, 
	FileInfo^ outputFile
)

Parameters

inputFile
Type: System.IO..::..FileInfo
File to be clear signed
privateKeyFile
Type: System.IO..::..FileInfo
Private Key file
privateKeyPassword
Type: System..::..String
Private key password
hashingAlgorithm
Type: DidiSoft.Pgp..::..HashAlgorithm
Hashing algorithm to be used
outputFile
Type: System.IO..::..FileInfo
Output file

Remarks

Clearsigned messages contain both the original message in clear text and the signature used to verify that the message comes from a trusted sender and has not been changed.

GPG equivalent command: gpg --output outputFileName --clearsign inputFileName

Examples

This example demonstrates how to OpenPGP clear sign a text file.
CopyC#
using System;
using System.IO;

using DidiSoft.Pgp;

class ClearSignFileExample 
{
 public static void Demo()
 {
    // create an instance of the library
    PGPLib pgp = new PGPLib();

    // clear text sign
    pgp.ClearSignFile(new FileInfo(@"DataFiles\INPUT.txt"), 
                      new FileInfo(@"DataFiles\private.key"), 
                        "private key password", 
                        HashAlgorithm.SHA256, 
                        new FileInfo(@"DataFiles\OUTPUT.sig.txt"));
 }
}
