----------------------------------

    Attachment: patch.txt

Patch adding a new method to allow access to the value as a BigInteger

> 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.
