Constructor Detail

AttributeCertificate

public AttributeCertificate(byte[] array)
                     throws java.security.cert.CertificateException

Creates a AttributeCertificate from a DER byte array.

Parameters:

array - the byte array containing the DER encoded certificate

Throws:

java.security.cert.CertificateException - if the format of the cert is wrong

AttributeCertificate

public AttributeCertificate(ASN1Object obj)
                     throws CodingException

Creates a AttributeCertificate from an ASN1 structure.

Parameters:

obj - the ASN1 structure that represents the certificate

Throws:

CodingException - thrown if the ANS1 structrue is incorrect

Method Detail

getEncoded

public byte[] getEncoded()

Returns this attribute certificate as as a DER encoded byte array.

Returns:

a byte array holding the DER encoded attribute certificate

decode

public void decode(ASN1Object asn)
            throws CodingException

Decode an AttributeCertificate from an ASN1Object.

Parameters:

asn - the ASN.1 type as ASN1Object

Throws:

CodingException - if there is a problem when parsing the certificate

getVersion

public int getVersion()
