Class X509Cert

java.lang.Object

COM.claymoresystems.cert.X509Cert

All Implemented Interfaces:

Certificate

public class X509Cert
extends java.lang.Object
implements Certificate

A single X509 Certificate.

The interface here does not match Sun's certificate interface, and even though that interface is pretty useless, we should still probably implement it.

Constructor Detail

X509Cert

public X509Cert(byte[] ber_)
         throws CertificateException

Create an X509Cert from an encoded value

Parameters:

ber_ - the encoded certificate as a byte[]

Currently this chokes if the cert is poorly encoded. We have to fix that to throw an IOException. TODO

Throws:

CertificateException

Method Detail

getPublicKey

public java.security.PublicKey getPublicKey()

Get the publicKey associated with this certificate

Returns:

the public key

getDER

public byte[] getDER()

Get the encoded form of this certificate

Specified by:

getDER in interface Certificate

Returns:

the encoded form

getIssuerDER

public byte[] getIssuerDER()

Get the encoded form of the issuerName

Specified by:

getIssuerDER in interface Certificate

Returns:

the DER encoded issuerName

getSubjectDER

public byte[] getSubjectDER()

Get the encoded form of the subjectName

Specified by:

getSubjectDER in interface Certificate

Returns:

the DER encoded subjectName

getSubjectName

public DistinguishedName getSubjectName()

Get the subject name as an X509Name

Specified by:

getSubjectName in interface Certificate

Returns:

an object representing the subjectName

getIssuerName

public DistinguishedName getIssuerName()

Get the issuer name as an X509Name

Specified by:

getIssuerName in interface Certificate

Returns:

an object representing the issuerName

getValidityNotBefore

public java.util.Date getValidityNotBefore()

Get the beginning of the validity window

Specified by:

getValidityNotBefore in interface Certificate

Returns:

the beginning of the certificate validity period

getValidityNotAfter

public java.util.Date getValidityNotAfter()

Get the end of the validity window

Specified by:

getValidityNotAfter in interface Certificate

the end of the certificate validity period

getExtensions

public java.util.Vector getExtensions()

Description copied from interface: Certificate

Get the vector of extensions (if any)

Specified by:

getExtensions in interface Certificate

Returns:

the extensions

getSerial

public java.math.BigInteger getSerial()

Get the serial number

Specified by:

getSerial in interface Certificate

Returns:

the serial number

verify

public boolean verify(java.security.PublicKey key)
               throws CertificateException

Check a certificate signature using the specified public key

Returns:

true if the signature checks, otherwise false

Throws:

CertificateException

verifyCertChain

public static java.util.Vector verifyCertChain(CertContext ctx,
                               java.util.Vector certs,
                               CertVerifyPolicyInt policy)
                                        throws CertificateException

Verify a certificate chain.

Parameters:

ctx - the cert context

certs - the certs to start with, ordered root first

Returns:

the canonicalized chain, with spurious certificates trimmed from the front and the root (if necessary) prepended

Throws:

CertificateException
