Certificate Class

Namespace:
GemBox.Spreadsheet.Security
Assembly:
GemBox.Spreadsheet.dll

Represents an X.509 certificate sent to others so that they can verify your digital signature with a public key contained in the certificate.

public class Certificate
Public Class Certificate
Inheritance:
System.Object
Certificate
Remarks

GemBox.Spreadsheet doesn't use System.Security.Cryptography.X509Certificates.X509Certificate2 class to represent a certificate because System.Security.Cryptography.X509Certificates.X509Certificate2 creates a file that holds the certificate with the public key (in various locations on a hard drive) and on some operating systems and platforms that file is not deleted unless System.Security.Cryptography.X509Certificates.X509Certificate2.Reset method is called. This creation of a file prevents usages of certificates in Medium Trust.

Another reason why GemBox.Spreadsheet abstracts a certificate with a Certificate class instead of using System.Security.Cryptography.X509Certificates.X509Certificate2 directly is to enable different implementations of a certificate. For example, either System.Security.Cryptography.X509Certificates.X509Certificate2 implementation from .NET or Org.BouncyCastle.X509.X509Certificate implementation from Bouncy Castle could be used.

Constructors

Certificate(Object)

Initializes a new instance of the Certificate class from the specified source.

The certificate source is an instance of a System.Security.Cryptography.X509Certificates.X509Certificate2.

public Certificate(object source)
Public Sub New(source As Object)
Parameters
source
System.Object

The certificate source that is an instance of a System.Security.Cryptography.X509Certificates.X509Certificate2.

Exceptions
System.ArgumentException

The source parameter is not an instance of a System.Security.Cryptography.X509Certificates.X509Certificate2.

Certificate(String)

Initializes a new instance of the Certificate class from a file with the specified file name.

public Certificate(string fileName)
Public Sub New(fileName As String)
Parameters
fileName
System.String

The name of a certificate file.

Exceptions
System.ArgumentNullException

fileName is null.

Properties

Subject

Gets the subject distinguished name from the certificate.

public string Subject { get; }
Public ReadOnly Property Subject As String
Property Value
System.String

The subject distinguished name from the certificate.

SubjectCommonName

Gets the value of a Common Name attribute from Subject's distinguished name.

public string SubjectCommonName { get; }
Public ReadOnly Property SubjectCommonName As String
Property Value
System.String

The value of a Common Name attribute from Subject's distinguished name.

Methods

Equals(Certificate)

Determines whether the specified Certificate is equal to this Certificate instance.

public bool Equals(Certificate other)
Public Function Equals(other As Certificate) As Boolean
Parameters
other
Certificate

The Certificate to compare with this Certificate instance.

Returns
System.Boolean

true if the specified Certificate is equal to this Certificate instance; otherwise, false.

Equals(Object)

Determines whether the specified System.Object is equal to this Certificate instance.

public override bool Equals(object obj)
Public Overrides Function Equals(obj As Object) As Boolean
Parameters
obj
System.Object

The System.Object to compare with this Certificate instance.

Returns
System.Boolean

true if the specified System.Object is equal to this Certificate instance; otherwise, false.

Overrides
System.Object.Equals(System.Object)

GetHashCode()

Returns a hash code for this Certificate instance.

public override int GetHashCode()
Public Overrides Function GetHashCode As Integer
Returns
System.Int32

A hash code for this Certificate instance, suitable for use in hashing algorithms and data structures like a hash table.

Overrides
System.Object.GetHashCode()

GetRawData()

Gets the copy of raw data of a Certificate.

public byte[] GetRawData()
Public Function GetRawData As Byte()
Returns
System.Byte[]

The copy of raw data of the Certificate as a byte array.

ToString()

Returns a System.String that represents this Certificate instance.

public override string ToString()
Public Overrides Function ToString As String
Returns
System.String

A System.String that represents this Certificate instance.

Overrides
System.Object.ToString()
Remarks

This method should be used primarily for debugging purposes and should be considered volatile (format of its return value might change in future versions).
