public Class X509V2AttributeCertificate

Implements org.bouncycastle.x509.X509AttributeCertificate.checkValidity.

Implements org.bouncycastle.x509.X509AttributeCertificate.checkValidity.

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

Implements org.bouncycastle.x509.X509AttributeCertificate.getAttributes.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getAttributes.

Return the attributes contained in the attribute block in the certificate.

Returns:X509Attribute[]

an array of attributes.

Implements org.bouncycastle.x509.X509AttributeCertificate.getAttributes.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getAttributes.

Return the attributes with the same type as the passed in oid.

Parameters

oid:String

the object identifier we wish to match.

Returns:X509Attribute[]

an array of matched attributes, null if there is no match.

Implements java.security.cert.X509Extension.getCriticalExtensionOIDs.

Doc from java.security.cert.X509Extension.getCriticalExtensionOIDs.

Gets a Set of the OID strings for the extension(s) marked CRITICAL in the certificate/CRL managed by the object implementing this interface. Here is sample code to get a Set of critical extensions from an X509Certificate and print the OIDs:

X509Certificate cert = null;
try (InputStream inStrm = new FileInputStream("DER-encoded-Cert")) {
    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    cert = (X509Certificate)cf.generateCertificate(inStrm);
}

Set<String> critSet = cert.getCriticalExtensionOIDs();
if (critSet != null && !critSet.isEmpty()) {
    System.out.println("Set of critical extensions:");
    for (String oid : critSet) {
        System.out.println(oid);
    }
}

Returns:Set<E>

a Set (or an empty Set if none are marked critical) of the extension OID strings for extensions that are marked critical. If there are no extensions present at all, then this method returns null.

Implements org.bouncycastle.x509.X509AttributeCertificate.getEncoded.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getEncoded.

Return an ASN.1 encoded byte array representing the attribute certificate.

Returns:byte[]

an ASN.1 encoded byte array.

Exceptions

IOException:

if the certificate cannot be encoded.

Implements java.security.cert.X509Extension.getExtensionValue.

Doc from java.security.cert.X509Extension.getExtensionValue.

Gets the DER-encoded OCTET string for the extension value (extnValue) identified by the passed-in oid String. The oid string is represented by a set of nonnegative whole numbers separated by periods.

For example:

Parameters

oid:String

the Object Identifier value for the extension.

Returns:byte[]

the DER-encoded octet string of the extension value or null if it is not present.

Implements org.bouncycastle.x509.X509AttributeCertificate.getHolder.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getHolder.

Return the holder of the certificate.

Returns:AttributeCertificateHolder

the holder.

Implements org.bouncycastle.x509.X509AttributeCertificate.getIssuer.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getIssuer.

Return the issuer details for the certificate.

Returns:AttributeCertificateIssuer

the issuer details.

Implements org.bouncycastle.x509.X509AttributeCertificate.getIssuerUniqueID.

Implements java.security.cert.X509Extension.getNonCriticalExtensionOIDs.

Doc from java.security.cert.X509Extension.getNonCriticalExtensionOIDs.

Gets a Set of the OID strings for the extension(s) marked NON-CRITICAL in the certificate/CRL managed by the object implementing this interface. Here is sample code to get a Set of non-critical extensions from an X509CRL revoked certificate entry and print the OIDs:

CertificateFactory cf = null;
X509CRL crl = null;
try (InputStream inStrm = new FileInputStream("DER-encoded-CRL")) {
    cf = CertificateFactory.getInstance("X.509");
    crl = (X509CRL)cf.generateCRL(inStrm);
}

byte[] certData = <DER-encoded certificate data>
ByteArrayInputStream bais = new ByteArrayInputStream(certData);
X509Certificate cert = (X509Certificate)cf.generateCertificate(bais);
X509CRLEntry badCert =
             crl.getRevokedCertificate(cert.getSerialNumber());

if (badCert != null) {
    Set<String> nonCritSet = badCert.getNonCriticalExtensionOIDs();
    if (nonCritSet != null)
        for (String oid : nonCritSet) {
            System.out.println(oid);
        }
}

Returns:Set<E>

a Set (or an empty Set if none are marked non-critical) of the extension OID strings for extensions that are marked non-critical. If there are no extensions present at all, then this method returns null.

Implements org.bouncycastle.x509.X509AttributeCertificate.getNotAfter.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getNotAfter.

Return the date after which the certificate is not valid.

Returns:Date

the "not valid afer" date.

Implements org.bouncycastle.x509.X509AttributeCertificate.getNotBefore.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getNotBefore.

Return the date before which the certificate is not valid.

Returns:Date

the "not valid before" date.

Implements org.bouncycastle.x509.X509AttributeCertificate.getSerialNumber.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getSerialNumber.

Return the serial number for the certificate.

Returns:BigInteger

the serial number.

Implements org.bouncycastle.x509.X509AttributeCertificate.getSignature.

Implements org.bouncycastle.x509.X509AttributeCertificate.getVersion.

Doc from org.bouncycastle.x509.X509AttributeCertificate.getVersion.

Return the version number for the certificate.

Returns:int

the version number.

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object.

Implements java.security.cert.X509Extension.hasUnsupportedCriticalExtension.

Doc from java.security.cert.X509Extension.hasUnsupportedCriticalExtension.

Check if there is a critical extension that is not supported.

Returns:boolean

true if a critical extension is found that is not supported, otherwise false.

Implements org.bouncycastle.x509.X509AttributeCertificate.verify.
