- - iaik.x509.extensions.netscape.NetscapeRevocationUrl

```
public class NetscapeRevocationUrl
extends V3Extension
```
This class implements the NetscapeRevocationUrl Extension.
Each Netscape certificate extension is associated with a specific certificateExtension object identifier, derived from:
```
 netscape OBJECT IDENTIFIER ::= { 2 16 840 1 113730 }
 netscape-cert-extension OBJECT IDENTIFIER :: = { netscape 1 }
 
```
The object identifier for the NetscapeRevocationUrl extension is defined as:
netscape-revocation-url OBJECT IDENTIFIER ::= { netscape-cert-extension 3 }
which corresponds to the OID string "2.16.840.1.113730.1.3".
The Netscape Certificate Specification specifies the NetscapeRevocationUrl extension as IA5String that represents a relative or absolute URL that can be used to check the revocation status of a certificate. The revocation check will be performed as an HTTP GET method using a url that is the concatenation of revocation-url and certificate-serial-number, where the certificate-serial-number is encoded as a string consisting of an even number of ascii hexadecimal digits. If the number of significant digits is odd, the string will have a single leading zero to ensure an even number of digits is generated. For example, if the netscape-base-url is https://www.certs-r-us.com/, the netscape-revocation-url is cgi-bin/check-rev.cgi?, and the certificate serial number is 173420, the resulting URL would be:
https://www.certs-r-us.com/cgi-bin/check-rev.cgi?02a56c
The server should return a document with a Content-Type of application/x-netscape-revocation. The document should contain a single ascii digit, '1' if the certificate is not curently valid, and '0' if it is curently valid.
You may specify a particular (relative or absolute) URL directly when creating a NetscapeRevocationUrl extension, or you may use the default constructor and supply the URL by using the setRevocationUrl method, e.g.:
```
 NetscapeRevocationUrl netscapeRevocationUrl = new NetscapeRevocationUrl();
 netscapeRevocationUrl.setRevocationUrl("cgi-bin/check-rev.cgi?");
 
```

- Field Detail
  - oid
```
public static ObjectID oid
```
    The object ID of the X.509 extension NetscapeRevocationUrl.
- Constructor Detail
  - NetscapeRevocationUrl
```
public NetscapeRevocationUrl()
```
    Default constructor. Creates an empty NetscapeRevocationUrl object.
    Use the setRevocationUrl method for specifying a particular (absolute or relative) URL value, e.g.:
```
 NetscapeRevocationUrl netscapeRevocationUrl = new NetscapeRevocationUrl();
 netscapeRevocationUrl.setRevocationUrl("cgi-bin/check-rev.cgi?");
 
```
  - NetscapeRevocationUrl
```
public NetscapeRevocationUrl(java.lang.String url)
```
    Constructs a NetscapeRevocationUrl extension with a specified URL.
    The (absolute or relative) URL is given as a String value, for instance:
    NetscapeRevocationUrl netscapeRevocationUrl = new NetscapeRevocationUrl("cgi-bin/check-rev.cgi?");
    
    Parameters:
    
    url - the revocation URL, as String
- Method Detail
  - getObjectID
```
public ObjectID getObjectID()
```
    Returns the object ID of this NetscapeRevocationUrl extension
    
    Specified by:
    
    getObjectID in class V3Extension
    
    Returns:
    
    the object ID
  - init
```
public void init(ASN1Object obj)
```
    Inits this NetscapeRevocationUrl implementation with an ASN1object representing the value of this extension.
    The given ASN1Object represents the IA5STRING (absolute or relative) URL value.
    The given ASN1Object is the one created by toASN1Object().
    This method is used by the X509Extensions class when parsing the ASN.1 representation of a certificate for properly initializing an included NetscapeRevocationUrl extension. This method initializes the extension only with its value, but not with its critical specification. For that reason, this method shall not be explicitly called by an application.
    
    Specified by:
    
    init in class V3Extension
    
    Parameters:
    
    obj - the NetscapeRevocationUrl as ASN1Object
  - toASN1Object
```
public ASN1Object toASN1Object()
```
    Returns an ASN1Object representing the value of this NetscapeRevocationUrl extension object.
    The returned ASN1Object represents the IA5STRING (absolute or relative) URL value.
    
    Specified by:
    
    toASN1Object in class V3Extension
    
    Returns:
    
    the value of this NetscapeRevocationUrl as ASN1Object
  - setRevocationUrl
```
public void setRevocationUrl(java.lang.String url)
```
    Sets the revocation url.
    The (absolute or relative) URL value is given as String, e.g.:
```
 NetscapeRevocationUrl netscapeRevocationUrl = new NetscapeRevocationUrl();
 netscapeRevocationUrl.setRevocationUrl("cgi-bin/check-rev.cgi?");
 
```
    Parameters:
    
    url - the revocation url, as String
  - getRevocationUrl
```
public java.lang.String getRevocationUrl()
```
    Returns the revocation url.
    
    Returns:
    
    the revocation url value as String
    
    See Also:
    
    setRevocationUrl(java.lang.String)
  - hashCode
```
public int hashCode()
```
    Returns a hashcode for this identity.
    
    Specified by:
    
    hashCode in class V3Extension
    
    Returns:
    
    a hash code for this identity
  - toString
```
public java.lang.String toString()
```
    Returns a string that represents the contents of this NetscapeRevocationUrl extension.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    the string representation
