Constructors Summary
public X509Extensions(org.bouncycastle.asn1.ASN1Sequence seq)
Constructor from ASN1Sequence. the extensions are a list of constructed sequences, either with (OID, OctetString) or (OID, Boolean, OctetString)

        Enumeration e = seq.getObjects();

        while (e.hasMoreElements())

public X509Extensions(Hashtable extensions)

it's is assumed the table contains OID/String pairs.
