DERInteger class provides no access to the full possible range of values a DERInteger can contain
-------------------------------------------------------------------------------------------------

                 Key: DIRSERVER-1351
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1351
             Project: Directory ApacheDS
          Issue Type: Bug
          Components: asn1
         Environment: any
            Reporter: Brad Davis
            Priority: Minor


ASN.1 encoded DERInteger objects are used for storing keypairs in base64 encoded public key
blocks  such as this one:

-----BEGIN RSA PUBLIC KEY-----
MIGJAoGBAMQgV2gXLbXgesWgeAsj8P1Uvm/zibrFXqwDq27lLKNgWGYGX2ax3LyT
3nzI1Y5oLs4kPKTsMM5ft9aokwf417lKoCRlZc9ptfRbgxDx90c9GtWVmkrmDvCK
ae59TMoXIiGfZiwWT6KKq5Zm9/Fu2Il3B2vHGkKJYKixmiBJRKp/AgMBAAE=
-----END RSA PUBLIC KEY-----

This contains a DERSequence of two DERInteger objects representing the public exponent and
the modulus of the key.  But the modulus is far to large to be represented by 'intValue()',
so there is no way to convert from this into a PublicKey object.
