public void encode(Asn1MderOutputStream out,
                   int length)

Encode this BIT STRING into the MDER encoding. The length of this BIT STRING must match the given length.

Parameters:

length - This should be 8, 16, or 32, as these are the only lengths MDER supports. However, this is not checked here as it should be able to be checked at code generation time. We only check here that the actual and given lengths match.

Throws:

Asn1Exception

java.io.IOException
