public void initialize(int keySize, java.security.SecureRandom secureRandom)
keySize
as input. It provides a simple use of the GMSS for
testing demands.
A given keysize
of less than 10 creates an amount 2^10
signatures. A keySize between 10 and 20 creates 2^20 signatures. Given an
integer greater than 20 the key pair generator creates 2^40 signatures.
keySize
- Assigns the parameters used for the GMSS signatures. There are
3 choices:secureRandom
- not used by GMSS, the SHA1PRNG of the SUN Provider is always
usedpublic void initialize(KeyGenerationParameters param)
