The X509Certificate class represents an X.509 certificate. This class
defines X.509 properties specified in
RFC2459. After you make a successful
call to SecureSocket.connect(), the server's certificate data is stored as
an X509Certificate instance in the SecureSocket.serverCertificate
property.
Use this class to examine a server certificate after establishing a secure
socket connection. The properties in this class provide access to the most
used attributes of an X.509 certificate. If you must access other parts of a
server certificate (for example, its extensions), the complete certificate
is available in the encoded property. The certificate stored in the
encoded property is DER-encoded.

Variables
read onlyencoded:ByteArray
Provides the whole certificate in encoded form. Client code can decode
this value to process certificate extensions. X.509 certificate
extensions are not represented in the other properties in this class.
Decoding the encoded property is the only way to access a
certificate's extensions.
read onlyserialNumber:String
Provides the serial number of the certificate as a hexadecimal string. The issuer assigns this number, and the number is unique within the issuer's list of issued certificates.
read onlysignatureAlgorithmParams:ByteArray
Provides the signature algorithm's parameters. If there are no signature
algorithm parameters, this value is set to null.
read onlysubjectPublicKeyAlgorithmOID:String
Provides the algorithm OID for the subject's public key.
read onlyversion:UInt
Provides the version number of the certificate format. This property indicates whether the certificate has extensions, a unique identifier, or only the basic fields.
version= 2: Indicates X.509 Version 3 - Extensions are presentversion= 1: Indicates X.509 Version 2 - Extensions are not present, but a unique identifier is present.version= null: Indicates X.509 Version 1 - Only the basic certificate fields are present
