Field Detail

### f

    protected org.bouncycastle.math.ec.ECFieldElement f

Constructor Detail

### X9FieldElement

    public X9FieldElement(org.bouncycastle.math.ec.ECFieldElement f)

### X9FieldElement

    public X9FieldElement(java.math.BigInteger p,
                          ASN1OctetString s)

### X9FieldElement

    public X9FieldElement(int m,
                          int k1,
                          int k2,
                          int k3,
                          ASN1OctetString s)

Method Detail

### getValue

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

### toASN1Object

    public DERObject toASN1Object()

  Produce an object suitable for an ASN1OutputStream.

        FieldElement ::= OCTET STRING

  1. 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.
  2. if q is 2m 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.

  Specified by:
    `toASN1Object` in class `ASN1Encodable`
