                  java.math.BigInteger b)

Method Detail

getQ

public java.math.BigInteger getQ()

fromBigInteger

public ECFieldElement fromBigInteger(java.math.BigInteger x)

Specified by:

fromBigInteger in class ECCurve

decodePoint

public ECPoint decodePoint(byte[] encoded)

Decode a point on this curve from its ASN.1 encoding. The different encodings are taken account of, including point compression for F_p (X9.62 s 4.2.1 pg 17).

Specified by:

decodePoint in class ECCurve

Returns:

The decoded point.

equals

public boolean equals(java.lang.Object anObject)

hashCode

public int hashCode()
