public KCcmBlockCipher(IBlockCipher engine)

Base constructor. Nb value is set to 4.

public KCcmBlockCipher(IBlockCipher engine, int Nb)

Constructor allowing Nb configuration. Nb is a parameter specified in CCM mode of DSTU7624 standard. This parameter specifies maximum possible length of input.It should be calculated as follows: Nb = 1 / 8 * (-3 + log[2]Nmax) + 1, where Nmax - length of input message in bits.For practical reasons Nmax usually less than 4Gb, e.g. for Nmax = 2^32 - 1, Nb = 4.
