InheritanceX509Certificate Inheritance Object

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

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.

Property Detail

encoded

property
encoded:ByteArray  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

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.



Implementation
    public function get encoded():ByteArray

issuer

property 
issuer:X500DistinguishedName  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the issuer's Distinguished Name (DN).



Implementation
    public function get issuer():X500DistinguishedName

X500DistinguishedName class

issuerUniqueID

property 
issuerUniqueID:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the issuer's unique identifier.



Implementation
    public function get issuerUniqueID():String

serialNumber

property 
serialNumber:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

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.



Implementation
    public function get serialNumber():String

signatureAlgorithmOID

property 
signatureAlgorithmOID:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the signature algorithm Object Identifier (OID).



Implementation
    public function get signatureAlgorithmOID():String

signatureAlgorithmParams

property 
signatureAlgorithmParams:ByteArray  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the signature algorithm's parameters. If there are no signature algorithm parameters, this value is set to null.



Implementation
    public function get signatureAlgorithmParams():ByteArray

subject

property 
subject:X500DistinguishedName  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the subject's Distinguished Name (DN).



Implementation
    public function get subject():X500DistinguishedName

Related API Elements

X500DistinguishedName class

subjectPublicKey

property 
subjectPublicKey:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the subject's public key.



Implementation
    public function get subjectPublicKey():String

subjectPublicKeyAlgorithmOID

property 
subjectPublicKeyAlgorithmOID:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the algorithm OID for the subject's public key.



Implementation
    public function get subjectPublicKeyAlgorithmOID():String

subjectUniqueID

property 
subjectUniqueID:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Provides the subject's unique identifier.



Implementation
    public function get subjectUniqueID():String

validNotAfter

property 
validNotAfter:Date  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Indicates the date on which the certificate's validity period ends.



Implementation
    public function get validNotAfter():Date

validNotBefore

property 
validNotBefore:Date  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

Indicates the date on which the certificate's validity period begins.



Implementation
    public function get validNotBefore():Date

version

property 
version:uint  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 11, AIR 3

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 present
  • version = 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


Implementation
    public function get version():uint
