- Method Detail
  - getCurveName
```
public String getCurveName()
```
    Returns:
    
    the curve name.
  - getEcParameters
```
public org.bouncycastle.jce.spec.ECParameterSpec getEcParameters()
```
    Returns:
    
    the ECParameterSpec.
  - getQ
```
public BigInteger getQ()
```
    Returns:
    
    the Q value of the curve.
  - determineCurveQ
```
protected abstract BigInteger determineCurveQ()
```
    Returns:
    
    the Q value.
  - getHalfN
```
public BigInteger getHalfN()
```
    Returns:
    
    halfN
  - getBitLength
```
public int getBitLength()
```
    Returns:
    
    the length of the curve order and keys in bits.
  - getByteLength
```
public int getByteLength()
```
    Returns:
    
    the length of the curve order and keys in bytes.
  - getByteLength
```
public static int getByteLength(org.bouncycastle.jce.spec.ECParameterSpec ecParameters)
```
    Parameters:
    
    ecParameters - the ECParameterSpec.
    
    Returns:
    
    the length of the curve order in bytes. This is also the length of the (compressed) keys except for a potential extra byte.
