Field Detail

DEFAULT_KEY_SIZE

public static final int DEFAULT_KEY_SIZE

The default bit length of the prime p (1024 bits)

Constructor Detail

SSVElGamalKeyGenParameterSpec

public SSVElGamalKeyGenParameterSpec()

Construct the default parameters. Choose the bit length of the prime p as DEFAULT_KEY_SIZE.

SSVElGamalKeyGenParameterSpec

public SSVElGamalKeyGenParameterSpec(int keySize)
                              throws InvalidParameterException

Construct new parameters from the given bit length of the prime p. If the length is invalid, the default length is chosen.

Parameters:

keySize - the bit length of the prime p (>= 512 bits)

Throws:

InvalidParameterException - if the key size is less than 512 bits.

Method Detail

getKeySize

public int getKeySize()

Returns:

the bit length of the prime p
