Field Detail

DEFAULT_SIZE

public static final int DEFAULT_SIZE

The default bit length of the discriminant (768)

MAX_SIZE

public static final int MAX_SIZE

The maximal bit length of the discriminant (16384)

Constructor Detail

IQDSAParamGenParameterSpec

public IQDSAParamGenParameterSpec()

Construct the default IQDSA parameter generation parameters. Choose the bit length of the discriminant as DEFAULT_SIZE.

IQDSAParamGenParameterSpec

public IQDSAParamGenParameterSpec(int size)

Construct new IQDSA parameter generation parameters from the desired bit length of the discriminant.

If the bit length of the discriminant is < 2, the DEFAULT_SIZE is used as bit length. If the bit length is > MAX_SIZE, MAX_SIZE is used as bit length.

Parameters:

size - the bit length of the discriminant (>= 2, <= MAX_SIZE)

Method Detail

getSize

public int getSize()

Returns:

the bit length of the discriminant
