Initializing the KX table
- The first three words of the KX table are initialized:
KX[0] = PI19 + sub-cipher number.
KX[1] = E19 * the key length.
KX[2] = R220 rotated left by the sub-cipher number of bits.
Where PI19, E19, R220 are internal "random" numbers.
- The remaining 253 words of the array are pseudo-randomly filled with:
KX[i] = KX[i-1] + (KX[i-2] ^ KX[i-3]>ᡏ ^ KX[i-3]<យ).
