The HttpClientCertificate type exposes the following members.
| Name | Description | |
|---|---|---|
 | AllKeys | Gets all the keys in the NameValueCollection. (Inherited from NameValueCollection.) |
| BinaryIssuer | Gets or sets the certificate issuer, in binary format. |
| CertEncoding | Gets the encoding of the certificate. |
| Certificate | Gets a string containing the binary stream of the entire certificate content, in ASN.1 format. |
| Cookie | Gets the unique ID for the client certificate, if provided. |
| Count | Gets the number of key/value pairs contained in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
| Flags | A set of flags that provide additional client certificate information. |
| IsPresent | Gets a value that indicates whether the client certificate is present. |
| IsReadOnly | Gets or sets a value indicating whether the NameObjectCollectionBase instance is read-only. (Inherited from NameObjectCollectionBase.) |
| Issuer | A string that contains a list of subfield values containing information about the certificate issuer. |
| IsValid | Gets a value that indicates whether the client certificate is valid. |
| Item[Int32] | Gets the entry at the specified index of the NameValueCollection. (Inherited from NameValueCollection.) |
| Item[String] | Gets or sets the entry with the specified key in the NameValueCollection. (Inherited from NameValueCollection.) |
| Keys | Gets a NameObjectCollectionBase.KeysCollection instance that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
| KeySize | Gets the number of bits in the digital certificate key size. For example, 128. |
| PublicKey | Gets the public key binary value from the certificate. |
| SecretKeySize | Gets the number of bits in the server certificate private key. For example, 1024. |
| SerialNumber | Provides the certificate serial number as an ASCII representation of hexadecimal bytes separated by hyphens. For example, 04-67-F3-02. |
| ServerIssuer | Gets the issuer field of the server certificate. |
| ServerSubject | Gets the subject field of the server certificate. |
| Subject | Gets the subject field of the client certificate. |
| ValidFrom | Gets the date when the certificate becomes valid. The date varies with international settings. |
| ValidUntil | Gets the certificate expiration date. |

If a Web browser uses the SSL3.0/PCT1 protocol (the URL begins with https:// instead of http://) to connect to a server and the server requires client certificates, the browser sends the client certificate fields contained in its digital certificate.
For more information about digital certificates, see the document X.509: Public-key and attribute certificate frameworks, available on the International Telecommunication Union (ITU) site at http://www.itu.int.
