Class CardVerifiableCertificate

java.lang.Object

java.security.cert.Certificate

org.jmrtd.cert.CardVerifiableCertificate

All Implemented Interfaces:

Serializable

public class CardVerifiableCertificate
extends Certificate

Card verifiable certificates as specified in TR 03110. Just a wrapper around org.ejbca.cvc.CVCertificate by Keijo Kurkinen of EJBCA.org, so that we can subclass java.security.cert.Certificate. We also hide some of the internal structure (no more calls to get the "body" just to get some attributes).

                                 CVCPrincipal holderReference,
                                 PublicKey publicKey,
                                 String algorithm,

                                 CVCAuthorizationTemplate.Permission permission,
                                 byte[] signatureData)

Constructs a certificate.

Parameters:

authorityReference - authority reference

holderReference - holder reference

publicKey - public key

algorithm - algorithm

notBefore - valid from date

notAfter - valid to date

role - role

permission - permission

signatureData - signed date

Method Detail

getSigAlgName

public String getSigAlgName()

Gets the signature algorithm.

Returns:

an algorithm name

getSigAlgOID

public String getSigAlgOID()

Gets the signature algorithm OID

Returns:

an OID

getEncoded

public byte[] getEncoded()
                  throws CertificateEncodingException

Returns the encoded form of this certificate. It is assumed that each certificate type would have only a single form of encoding; for example, X.509 certificates would be encoded as ASN.1 DER.

Specified by:

getEncoded in class Certificate

Returns:

the encoded form of this certificate

Throws:

CertificateEncodingException - if an encoding error occurs.

getPublicKey

public PublicKey getPublicKey()

Gets the public key from this certificate.

Specified by:

getPublicKey in class Certificate

Returns:

the public key.

toString

public String toString()

Returns a string representation of this certificate.

Specified by:

toString in class Certificate

Returns:

a string representation of this certificate.

verify

public void verify(PublicKey key)
            throws CertificateException,
                   NoSuchAlgorithmException,
                   InvalidKeyException,
                   NoSuchProviderException,
                   SignatureException

Verifies that this certificate was signed using the private key that corresponds to the specified public key.

Specified by:

verify in class Certificate

Parameters:

key - the PublicKey used to carry out the verification.

Throws:

NoSuchAlgorithmException - on unsupported signature algorithms.

InvalidKeyException - on incorrect key.

NoSuchProviderException - if there's no default provider.

SignatureException - on signature errors.

CertificateException - on encoding errors.

verify

public void verify(PublicKey key,
                   String provider)
            throws CertificateException,
                   NoSuchAlgorithmException,
                   InvalidKeyException,
                   NoSuchProviderException,
                   SignatureException

Verifies that this certificate was signed using the private key that corresponds to the specified public key. This method uses the signature verification engine supplied by the specified provider.

Specified by:
