public class Certificate : IDisposable

The Certificate type exposes the following members.

Public methodCertificate(X509Certificate2)
Initializes certificate from X509Certificate2 object.
Public methodCertificate(Byte, CertFileType, String)
Loads the certificate from binary data and returns it as Certificate object.
Public methodCertificate(String, CertFileType, String)
Loads the certificate from a file and returns it as Certificate object.
Public methodDispose
Releases the resources associated with the Certificate object.
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodStatic memberLoadFromFileAsync
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodSaveToFile
Saves the certificate into a file on disk.
Public methodSaveToFileAsync

Returns a string that represents the current object.
(Inherited from Object.)
Public methodCode exampleValidate
Checks if the certificate is valid.
Public methodValidate(X509Certificate2Collection)

Public propertyCode exampleSerialNumberString
Gets the serial number of the X.509-formatted certificate as a string.
Public propertyCode exampleSignatureAlgorithm
Gets the information about cryptographic algorithm used to sign the certificate.
Public propertyCode exampleSubject
Gets the subject of X.509 certificate.
Public propertySubjectAlternativeName
Gets the subject's alternative name of X.509 certificate.
Public propertyThrowExceptions
Gets or sets whether the object will throw exceptions on errors.
Public propertyThumbprint
Gets the thumbprint of a certificate.
Public propertyCode exampleValidFromDate
Gets the date the certificate is valid from.
Public propertyCode exampleValidToDate
Gets the date the certificate certificate is no longer valid from.

Certificate class represents a digital certificate in MailBee.

Digital certificate is a statement which uses a digital signature to bind together a public key of an entity with information about this entity. After the trusted organization (also called a certification authority, CA) has verified the entity, it issues the requested certificate to the entity.

Certificates can contain different types of data, such as the serial number of the certificate, the algorithm used to sign the certificate, the name of the CA that issued the certificate, the name and public key of the entity requesting the certificate, and the CA's signature.

EmailAddress and HasPrivateKey are the most important properties of the certificate.

Note Note
To use this class, make sure MailBee.NET Security is licensed (MailBee.NET Objects full bundle does include the license).
Note Note
Starting from .NET Standard 2.0 edition (e.g. .NET Core 2.0 and newer), it's recommended to use system-provided X509Certificate2 and X509Certificate2Collection classes directly. The only case when you'll need Certificate or CertificateCollection is calling SignAndEncrypt(MailMessage, Certificate, CertificateCollection) method. You can use Certificate(X509Certificate2) and FromX509Certificate2Collection(X509Certificate2Collection) methods to wrap X509Certificate2 and X509Certificate2Collection objects with their MailBee counterparts.
This sample loads the certificate from the specified file and displays its fields.
// To use the code below, import MailBee namespace at the top of your code.
using MailBee.Security;

// The actual code (put it into a method of your class).
Certificate cert = new Certificate(@"C:\Temp\certificate.cer", CertFileType.Cer, null);

Console.WriteLine("Email address: " + cert.EmailAddress);
Console.WriteLine("Private key available: " + cert.HasPrivateKey);
Console.WriteLine("Issued by: " + cert.IssuedBy);
Console.WriteLine("Issued to: " + cert.IssuedTo);
Console.WriteLine("Issuer: " + cert.IssuedBy);
Console.WriteLine("Key algorithm: " + cert.KeyAlgorithmString);
Console.WriteLine("Name: " + cert.Name);
Console.WriteLine("Public key: " + cert.PublicKeyString);
Console.WriteLine("Serial number: " + cert.SerialNumberString);
Console.WriteLine("Subject: " + cert.Subject);
Console.WriteLine("Valid from " + cert.ValidFromDate + " till " + cert.ValidToDate);
