Method Detail

getValue

public org.bouncycastle.math.ec.ECFieldElement getValue()

toASN1Primitive

public ASN1Primitive toASN1Primitive()
Produce an object suitable for an ASN1OutputStream. FieldElement ::= OCTET STRING

if q is an odd prime then the field element is processed as an Integer and converted to an octet string according to x 9.62 4.3.1. if q is 2 m then the bit string contained in the field element is converted into an octet string with the same ordering padded at the front if necessary.

Overrides:
toASN1Primitive in class ASN1Object
Following copied from class: org.bouncycastle.asn1.ASN1Object
Returns:
a primitive representation of this object.
